What to do if the laptop does not boot

Inactive hard disk partition

This situation is not common, but you still need to talk about it, otherwise the article can be said to be truncated. Let’s give an example, after which you will understand what’s what.

Let’s say you have several Windows operating systems installed on your computer, which are installed on different hard drives. If you assign incorrect attributes to hard disk partitions, then you will have problems loading a particular version of Windows.

To check or fix this, you can use the Acronis Disk Director boot disk to change the attributes of the partitions. So, download and burn the Acronis Disk Director boot disk and boot from it. How to do it? Insert the disc into the drive, restart the computer, and it will boot from the disc that is in the drive. But before that, check your boot priorities. There should be a CDRom, as in a Windows installation. We already talked about this in this article above.

When the program loads, pay attention to the flags that are on the hard disk partitions.

laptop, does, boot

In the image above, we can see that the checkboxes are on the second partitions of the hard drive. You need to make these checkboxes on the first sections. We got to practice;). You need to click on each first partition of the hard disk with the right mouse button and select “Mark as active”.

A message should appear where you click “OK”. This is what it looks like after the whole procedure:

Now it remains to click on the “Run” checkbox, wait for the operation to complete and restart the computer. Remember to remove the disc from the drive.

System Restore

First of all, you can use the function that is in the installation disc “System Restore”. I will give an example of a Windows 7 system, but if you have a different system, then this is not a reason to think that you cannot do it on your system. The names of the buttons may differ, but the principle remains.

So, for this procedure, we need a Windows installation disc or its image (you can download it on the Internet). If you do not have the opportunity to download the image or do not have a disk, then write to me at useroffcom@gmail.com or contact your friends who have already installed Windows on their own.

If you do not have a working floppy drive or it does not exist at all, then the article “Creating an installation USB flash drive for Windows 7” will help in creating a bootable USB flash drive.

When you have a Windows distribution kit available, insert it into the drive and restart your computer. If the BIOS is configured for installation, then you will see the line:

When it appears, press any key.

In the event that it is not there or Windows boots as usual, then it is necessary to perform manipulations in the BIOS. Namely, set the priorities of the download. Usually, the hard drive is set in the BIOS settings, since it is on it that your Windows is installed.

In order for the computer to start booting from the disc that is in your floppy drive, you need to go into the BIOS and specify CDRom as the first device to boot. I already talked about this above, if you have not read this moment, then it’s time to do it.

So, you pressed any key, now a window will appear where you click “Next”.

In the next window you need to click “System Restore”.

This will search for installed systems. If you have one system installed, then, accordingly, there will be one operating system in the list. Select it and click “Next”.

Often at this stage, a message may appear in which you will be prompted to restore the system. If this message is displayed on your screen, then click “Fix and restart”. After that, try to log into your account.

If the message does not appear, then in the next window you select your system and click “Next”.

After that, a window will appear where you can choose how to restore the system.

Startup repair. automatic solution to the problem.

System Restore. you can use this method, but provided that this function has been enabled.

System image recovery. if you have a Windows image to recover.

Command Prompt. You can revive Windows with specific commands. Further, this method will be considered.

Now click “Startup Repair”. Now you need to wait a little for the utility to try to automatically find the problem and solve it.

Basic solutions when Windows refuses to boot

The topic that I want to discuss in this article is very popular and to tell about it in detail so that you understand how and what to do is not so simple. But still, I will try to describe possible ways of what to do if Windows 7 does not boot on a laptop or computer. We will also find out why this could happen ?! The task is not an easy one for us, namely, to correct the current situation, but there is no need to be afraid. Just follow the clear instructions and you will be fine! Some points may be suitable for other operating systems, but the emphasis will be on Windows 7.

Dear reader, if you really want to solve the problem, then I strongly recommend that you read the article completely, and then draw some conclusions. I cannot tell you about all the nuances in one paragraph.

Windows may need to be reinstalled

This option should be considered when you tried to revive Windows, but all attempts did not share results.

I will not dwell on the installation of Windows in detail, since I wrote about this on my blog:

I also recommend watching the video if you are installing Windows for the first time here.

Here is a quick guide: since you do not have access to the desktop, go to the BIOS, look for the Boot or Advanced BIOS Features tab, or search for yourself. Then already in it we find the line “1st Boot Device”, set the CD-ROM value. What have we done? And what we did is that now the computer will boot from the disk that is installed in your CDRom, and not from the hard disk when it boots. After switching on, when the inscription “Press any key” appears on a black background, press any button and get into the Windows installation wizard. Then follow the instructions on the screen.

You can read more about how to boot from disk in my article: “How to set boot priorities in BIOS”.

I decided to tell you about the installation at the very beginning, because if you were going to reinstall Windows, then perhaps this is some kind of sign to implement it))). But as I said at the very beginning, we will now try to bring your Windows back to life without reinstalling it.

System recovery via command line

So, if the above recommendations did not help, then now we will restore the system using the command line. To open this window, click “Command Prompt”.

Then enter Bootrec and press Enter.

A list of commands that can be used in this utility will appear, now you need to enter: Bootrec.exe / FixMbr and press Enter.

Now enter Bootrec.exe / FixBoot and then hitting Enter. Next, exit the utility by typing exit and pressing Enter. Now you can try to boot into your account, as the restoration work is over.

You can also try updating the boot code by entering the bootsect / NT60 SYS command. Then exit with the Exit command.

If the above commands did not help you, then go to the command line and enter Bootrec.exe / RebuildBcd. With this command you will scan your hard drive to find the systems installed on it.

When the scan is finished, a list of installed operating systems on your hard drive will appear. To add it to the boot list, press Y and Enter. After successful completion of the operation, type Exit and press Enter.

So, we figured it out with the command line. In principle, this should help to get your system to boot.

Safe Mode and Last Known Good Configuration

This is a must try! Restart the computer, press the F8 key continuously.

Attention! Entering Safe Mode is slightly different in Windows 8, so it’s best to follow the link below for all the details. In the list that appears, we are interested in the item called “Last Known Good Configuration (optional)”. Select and press Enter.

How to enter Safe Mode on different systems:

What to do if the information above did not help you? We repeat the actions described in the previous paragraph, but choose “Safe Mode”.

Then you can make a choice: fix the problem due to which Windows 7 does not boot manually, or try to do it in semi-automatic mode. Usually I do everything manually, for example, if Windows does not boot after installing the drivers, then I uninstall the drivers and try to boot. I think you understand that the manual method requires more knowledge from you, so Windows offers you another option, which I will describe below.

If everything boots, go to the Start menu, Control Panel, System and Security. In the “Support Center” tab, click on the words “Restore the previous state of the computer”. See the Start System Restore button? Great, so you’ve come to the right place.

Now click it and follow the instructions.

Next, you will need to select a restore point. In my case, I am asked to select a point on the 23rd, and now the calendar is on the 29th. Therefore, you need to click on “Search for affected programs” to find out what actions you will need to take after recovery.

So, you have familiarized yourself with the affected software during System Restore and now you can close this window. After closing the window, click “Next”.

If you were unable to enter Safe Mode to restore Windows, then don’t despair. Below we will analyze another method.

Note: at the very beginning, when Windows 7 was just coming out, there was one strange glitch, which you may have. When you turn on the computer, a welcome screen follows and a black screen appears. As I remember, there seemed to be an arrow, but nothing else was visible. The treatment is very simple. go into safe mode and restart your computer as usual. After that, I managed to log into my account without any additional manipulations with Windows.

Hardware problems, BIOS and viruses

HDD. If your system unit, or rather the hard drive, makes suspicious sounds: clicks or tapping, then there is a chance that you need to replace the hard drive. To make sure of this, you need to open the lid of the system unit, turn on the computer and listen to the hard drive. Also check the hard drive wiring. It is possible that the wires are disconnected and the computer cannot see the hard drive.

If you suspect that there is a problem with the hard drive, then you need to copy all important data to another medium. Otherwise, you may lose them altogether.

BIOS. Go to BIOS settings and put the hard drive in the first place so that it starts booting from it. Above, we analyzed an example when we exposed a CDROM, and do the same with a hard disk. Just do not forget to save the changes in the BIOS by pressing the F10 key.

The second way. you will not believe it, but it really works! Just go into the BIOS and, without changing anything there, exit, saving the changes, which in fact were not there (by pressing the F10 button). I personally once fixed a laptop to friends, and when they asked me how I did it, my answer was: “Magic and nothing else “. So try it, all of a sudden it turns out to be much easier than you think.

Viruses. Sometimes viruses prevent Windows from booting. If there are viruses on your computer, then you need to check the entire disk for viruses. Here are the articles that will be useful to you: “Checking for viruses” and “Will the antivirus withstand the blow or lose concentration?”.

Of course, if you check your hard drive for viruses, then you will need to disconnect it and connect it to another computer, since in your case Windows will not boot. Or you can use special boot programs with which you can scan your computer for viruses even if you cannot boot your Windows. Here are a couple of them: Kaspersky Rescue and Dr.Web® LiveDisk.

Attention! There are cases when after installing updates Windows 7 stopped loading! Therefore, you can try to uninstall the recent updates that were installed before the Windows boot problem appeared.

Important! If you see a specific error on your screen, then I recommend using the search in Google or Yandex. You can enter into the search not only the error code, but also the words that are used in it. Thus, you will save your time searching for the problem and its solution.

Important! If the system unit emits squeaks when it is turned on, then it is necessary to determine the problem by this squeak. Ask how? Here is an article for you on this topic: “Why does the computer beep when turned on and what are BIOS signals”.

That’s all I wanted to say. The article turned out to be great, and I sincerely hope that at least one of the methods I have described helped you.

He says a lot, but there is some useful information for you:

If the laptop won’t turn on

Hello dear laptop owners!

If the laptop does not turn on, you should carefully inspect the case. If during the check in the warehouse, everything worked fine, and problems began at home, you probably did not encounter such a sad factor as a factory defect. But more on that later. As part of today’s article, I want to tell you about the tactics of “home” diagnostics of a laptop and, of course, we will try to eliminate the simplest breakdowns.

Laptop does not turn on. What does it mean?

Let’s start with the most frightening symptom. the laptop won’t turn on. There are no signs of life, despite the not sickly efforts of users. Indeed, it is very scary when your laptop refuses to turn on. What does this mean. First of all, check the battery! It is possible that the battery has run out quickly, so the motherboard is not receiving the power it needs. In such cases, it is recommended to connect the laptop to a charger. Press the power button and if the device comes to life, then the problem is solved, if not, then read on.

It is possible that the problem lies in the battery itself. Although lithium is a quality material, it can quickly lose its properties. Connect the charger to your laptop and remove the battery. If everything is ok, the car will start without any problems. You just have to replace the battery. This usually happens due to prolonged downtime of the laptop in the warehouse. The product is stale and, accordingly, deteriorates.

Let’s assume your desktop battery is good. Why won’t my laptop turn on? Let’s check the power supply, perhaps because of it your laptop is not receiving power, therefore, the battery is not charging. A small power indicator is always present on a PSU of this type. Connect the power supply unit to the network and if the LED lights up, it means that the device is working properly. You can check its performance using a simple voltmeter. The voltage at the input must be at least 20 V, therefore, the multimeter must be switched to position 20. Then we look at the indicator, if the deviation is small, then the power supply unit is working properly.

If possible, power up a spare power supply and test the machine on it. If the laptop still does not turn on, then it smells like kerosene!

If the laptop does not turn on, check the power button mechanism. The procedure is very unpleasant, especially for those who are afraid to disassemble computer cases. It is possible that the mechanism itself was damaged during assembly. By the way, if the button is pressed tightly, then you are probably faced with just such a case. In general, you will have to open the case and check what is wrong (If the laptop is new or under warranty, then I advise you to take it to the SC). At last, check again if the power supply and battery are working.

The worst thing is when a new laptop does not turn on even with a working battery and power supply. The motherboard of a laptop also cannot “live forever”, keep this in mind. It is very difficult to eliminate power breakdowns on the motherboard, especially if you do not have the necessary experience and knowledge. With such a problem, it is better to contact service centers. Any breakdown on the motherboard is complicated by the fact that all the components on it are “tightly” soldered (but not always). Due to such a solid assembly, you will not be able to replace the processor or video chip, unless, of course, something of this is out of order. In such cases, it is customary to buy a new motherboard, which will certainly inflict an unpleasant blow on your ! In any case, such breakdowns must be repaired under warranty.!

Now let’s move on to more “typical” problems. If the laptop does not turn on well, the system works slowly, then I recommend opening the case again. This time, look for the problem not with the power button, but with the dustiness of the motherboard and cooling system. Remove the battery carefully, disassemble the case and wipe the board with a dry cloth. Do not use force to avoid damaging the motherboard. Be sure to clean and lubricate the cooler! It will be difficult to get to it, so you can arm yourself with a vacuum cleaner. By the way, check the condition of the thermal paste on the processor and video chip, if it is dry, replace it.

Software level problems

Laptop won’t boot, what should I do? It is not uncommon for users to see only a black screen instead of the familiar Windows Welcome screen. Sometimes it happens the other way around, the system boots up normally, after which everything goes out. Usually, the problem lies in the operating system itself. The malicious program has stuck deep in the registry, or the user himself has tricked something.

The culprit for the appearance of a black screen may be a crooked video card driver. Such complaints certainly arise from owners of outdated video cards. Installing the latest drivers on outdated hardware does not always add performance. In most cases, it turns out the other way around. By the way, besides the black screen, you can stumble upon the blue screen of death. It displays a bunch of inscriptions, among which you should find the error code and drive it into the search engine. This way you will find out what happened to your car.

Loops, matrix, VGA cables

The laptop is noisy, but won’t turn on, giving out a black and lifeless screen. Obviously, the problem again lies in the video card. The video chip flew or the loop connecting the motherboard and the video card refused to work. By the way, don’t be surprised if any other cable or connector gets damaged. It will be possible to check this only in specialized service centers.

A dark screen may occur due to sensor issues. Naturally, the display will be black, but the laptop itself will work. Try connecting your laptop to a separate monitor or TV via VGA. If everything works, then you will need to replace the display matrix. Yes, and check if the VGA cable you intend to use works. Try replacing it with a different one if nothing is displayed on the new monitor.

A couple of times I got questions about what to do if a dark display with a bunch of incomprehensible characters and encodings appears instead of the loading screen. Naturally, the laptop does not boot, and the user starts to panic. Unfortunately, there is no universal solution to such questions, except to use a search engine. Just type in the error code or any other information from this screen, and good old Google will tell you what to do. Believe me, you are not the only one on the planet who faces such mistakes.

Laptop won’t boot or turn on? Now this problem should recede into the background. And do not hesitate to seek help from experienced users who probably know how to proceed specifically in your case. Good work!


There are several options for the reasons for the error on the Windows 10 INACCESSIBLE_BOOT_DEVICE blue screen. Sometimes this is just a bug when updating or resetting the system, sometimes it is a consequence of changing the structure of partitions on the hard disk. Less commonly, physical problems with the hard drive.

If in your situation Windows 10 does not start with this particular error, you will find detailed steps to fix it, starting with simple ones and ending with more complex ones, in the article: How to fix the INACCESSIBLE_BOOT_DEVICE error in Windows 10.

Windows 10 won’t start

Questions about what to do if Windows 10 does not start, constantly reboots, a blue or black screen at startup, reports that the computer does not start correctly, Boot Failure errors are some of the most frequently asked by users. This article contains the most common errors that prevent your Windows 10 computer from starting and how to solve the problem.

When fixing such errors, it is always useful to remember what happened to the computer or laptop just before that: Windows 10 stopped starting after updating or installing antivirus, perhaps after updating drivers, BIOS or adding devices, or after an improper shutdown, a dead laptop battery, etc. P. All this can help to correctly identify the cause of the problem and fix it.

Attention: the actions described in some instructions can lead not only to fix Windows 10 startup errors, but in some cases also to the fact that they will get worse. Take these steps only if you are ready for it.

“The computer did not start correctly” or “Windows does not seem to boot correctly

The first common variant of the problem is when Windows 10 does not start, but instead first (but not always) reports some error (CRITICAL_PROCESS_DIED, for example), and after that. a blue screen with the text “The computer has not started correctly” and two options for actions. restarting the computer or additional parameters.

Most often (with the exception of some cases, in particular, INACCESSIBLE_BOOT_DEVICE errors), this is caused by damage to system files due to their deletion, installation and removal of programs (often antiviruses), the use of programs to clean the computer and the registry.

You can try to solve such problems by repairing corrupted files and the Windows 10 registry. Detailed instructions: The computer does not start correctly in Windows 10.

Boot Failure and An operating system wasn’t found errors

Another common variant of the Windows 10 startup problem is a black screen with the Boot failure error text. Reboot and Select Proper Boot device or insert boot media in selected boot device or An operating system wasn’t found. Try disconnecting any drives that don’t contain an operating system. Press CtrlAltDel to restart.

In both cases, unless it is the wrong order of the boot devices in the BIOS or UEFI and the damage to the hard disk or SSD, a corrupted Windows 10 boot loader is almost always the cause of the startup error. Steps to help fix this error are described in the instructions: Boot Failure and An operating system wasn’t found on Windows 10.

The Windows 10 logo appears and the computer shuts down

The causes of the problem when Windows 10 does not start, and the computer turns off itself, sometimes after several reboots and the appearance of the OS logo, is similar to the first described case and usually occurs after an unsuccessful automatic startup fix.

Unfortunately, in this situation, we cannot get into the Windows 10 recovery environment available on the hard drive, and therefore we need either a recovery disc or a bootable USB flash drive (or disk) with Windows 10, which will have to be done on some other computer ( if you do not have such a drive).

For details on how to boot into the recovery environment using an installation disc or a USB flash drive, see the Windows 10 recovery disc. After booting into the recovery environment, we try the methods from the section about “The computer has not started correctly”.

Black screen when starting Windows 10

The problem when Windows 10 won’t start and instead of the desktop you see a black screen has several options:

  • When, judging by everything (for example, by the OS welcome sound), in reality everything starts, but you see only a black screen. In this case, use the Windows 10 Black Screen instruction.
  • When, after some action with disks (with partitions on it) or an incorrect shutdown, you first see the system logo, and then immediately a black screen and nothing else happens. As a rule, the reasons for this are the same as in the case of INACCESSIBLE_BOOT_DEVICE, try using the methods from there (the instructions indicated above).
  • Black screen, but there is a mouse pointer. try the methods from the article The desktop does not load.
  • If after turning on neither the Windows 10 logo nor even the BIOS screen or the manufacturer’s logo appears, especially if before that you already had problems starting the computer the first time, the following two instructions will be useful to you: The computer does not turn on, The monitor does not turn on. I I wrote them quite a long time ago, but in general they are still relevant now and will help you figure out exactly what the matter is (and it is most likely not in Windows).

So far, this is all that I managed to organize from the most common problems for users with the launch of Windows 10 at the current time. Additionally, I recommend that you pay attention to the article Restoring Windows 10. perhaps it can also help with solving the described problems.

Hello Dmitry. The problem is this. I noticed that the laptop on Windows 10 began to slow down in the game. Disconnected it via the button. After a while I turned it on. It starts up to the lock screen and then the cycle begins. At the same time, it reacts to responses. But it does not even let me into the password input field. Broke his head what’s the trouble. Tried rolling back the system did not help.
Does not start up in safe mode.
There are no flash drives to roll back Windows.
Here on YouTube I found a video with my problem. Help me please

READ  How to connect HDMI to a TV from a laptop

The first time I see this as in the video.
And how did you roll back the system? You write that you did not help, it means that you somehow managed to do?
If suddenly not, then still try somewhere to create a bootable USB flash drive with a 10 (this can be done even on a phone), boot from it, and on the second screen at the bottom left, click “System Restore”, and then use restore points.

Hello. I have such a situation: after the second warranty repair of the mini PC, Windows 10 does not boot. the first time you turn it on, the system boots up, but after

0.5 minutes everything freezes and. silence. And the next time you turn it on, the message “Intel UNDI, PXE-2.1 (build 083)” appears, etc. At the same time, the SSD is visible in the BIOS and has priority among boot devices. The first repair happened due to the fact that the PC stopped turning on for no apparent reason. Any advice? thank.

You should see what you had there and what was repaired. Simply, according to the description, there may be different options, starting with accidentally “badly connected the cables” ending with “changed the power supply to one that is already becoming unusable”.
But just in case: in the BIOS, in the priorities, you can select not SSD but Windows Boot Manager? If yes, select it.

Good afternoon. I recently changed Windows 10 login on laptop. Previously, when turned on, the logo and entrance immediately appeared, but now for some reason a blue screen, and on it: Select the operating system 1) Windows Recovery Environment 2) Windows 10 and slightly lower Change the default settings. How to fix it?

Go to Windows 10, there press the WinR keys on your keyboard, type msconfig and press Enter. On the “download” tab, delete the unnecessary item.

Updates were being installed, my son accidentally turned off the laptop, then I tried to turn it on and we had a problem with the PC. It was launched incorrectly, it rebooted a lot, and when we clicked “Restart” it did not help in any way. help us please!

There, on the screen about the incorrect launch, there should be an item “Advanced options” and there are recovery options using recovery points or even a system reset.

Good day. I decided to upgrade to Windows 10, installed it, and started installing drivers. After installing all the drivers, it rebooted. The PC showed the Windows logo and froze on a black screen with spinning circles. And after the usual shutdown, it turned on normally. I thought that because of the drivers, I installed Windows again and pressed restart. the problem is the same. What to do?

Can’t wait? In theory, some update tasks can be performed.
Do I understand correctly that there is a problem when restarting, there is no problem when shutting down?

Yes, only on reboot. over, after an unsuccessful reboot, the PC refuses to show the slave. table. At each next restart, it hangs at the stage of “circles”
P. S installed Windows 7 and the problem went away

Thank you so much! It helped, otherwise I was going to reinstall

Hello Dmitry! After reboots after different updates, the processor buzzes under load, the screen is black and a window with resolution numbers runs across the monitor screen. You need to wait from 15 minutes to an hour until the system unit calms down, then the startup is normal. What’s the matter. what’s wrong.
Windows 10.motherboard old BIOS 2010
You have to wait after turning off the computer from 15 to an hour

Hello. Does this happen at shutdown? If so, try disabling Fast Startup https://remontka.pro/fast-startup-Windows-10/

Hello, such a misfortune has happened. After cleaning the PC, Windows 10 refused to start. At first I thought that the loading priorities were lost and set it as before. it did not work. When loading, it writes something in the spirit of “load wondows file” (as when installing Windows) and throws it into the menu with the choice “continue logging into Windows 7 (?) Or start system restore.” As a result, I was able to start only by prioritizing Windows Boot Manager, but now booting from the start instead of the usual 10 seconds takes 25 (the system took a very long time to boot). There are two disks in the computer, on the second one there is no Windows, and even images are not there. Google didn’t help, hope for your advice

It may turn out that the second disk does not have Windows, but there is a boot loader for Windows, which is on the first disk on a hidden partition. It’s hard to say without seeing the situation, but given the fact that when Windows Boot Manager is loaded, it is possible that this is exactly the case.
Also, in theory, regardless of the choice of Windows Boot Manager or the correct disk, the boot should take the same amount of time, so it seems that this is something else. And in what, not knowing what exactly you were doing, I do not know.

Hello, I have a problem like this:
The day before, I used a PC, everything was fine, after turning it back on the next day, the PC stopped playing Windows. After a long download, a black screen appears. Tried many restorations and nothing helped. help

After disconnecting by a long hold, for a few seconds, the power button (on a black screen) and then turning it on again does not start either?

Such a problem, the laptop has Windows 10. When turned on, for no reason at all, it began to slow down very much. The screen turns on for 10 minutes to the desktop for the same amount and then there is silence, all the icons on the desktop are immersed. I have an auto launch of Opera, the laptop was loaded all night, but it did not start anything. Does not respond to any clicks, but the mouse moves perfectly, it is impossible to call any services (task manager).
What could be the problem, tell me.
I was thinking about food. It only works when charging is on. Could he just lack energy? Although it used to work fine under the same conditions.

Doesn’t look like food according to your description.
Looks more like either a full system hard drive partition (or hard drive problems) or malware.

Kind time of the day, see I have such a problem so that I don’t do anything, it doesn’t help, the computer was turned off urgently, after restarting Windows, it showed an error code 0x0000001, then I pressed continue logging in, after which I got a blue screen like on your first photo about “The computer has not started correctly” or “It seems that Windows has not started correctly”, But! after the end of the reboot process, the computer does not reboot but simply turns off, when you select to enter the safe mode, the same thing, I can not enter the BIOS, what should I do? help me please)

Is there an item in the recovery environment (blue screen with actions) to enter the UEFI settings? If there is, then it should lead to BIOS. There should also be an item for using restore points, and the command line will allow you to check the disk for errors, since it may be they.

I do not have this, I first have a blue screen by mistake that I wrote to you above, and there are three points, 1) press enter to try again, 2) press F8 to access the boot options, 3) press F9 to choose another operating system, when I press f8, it knocks out a menu in which no matter what I press, the system is turned off again, but thanks to the Windows which is the second, I can enter the system, so one worker does not want the second (

I’m afraid, without seeing the situation with my own eyes, I don’t even know what to advise. There may be problems with the bootloader, but I’m not at all sure about this.

I can take a photo for you, just tell me where to take it off?

BIOS does not start: what to do and how to “revive” the microsystem

The basic I / O system is the beginning of the electronic life of a computer. In the event of a hardware or software malfunction of the BIOS microchip, a safe start of the computing device simply becomes impossible. Despite the extreme degree of reliability of the specified element of the computer system, software failures in the basic microsystem (in view of many factors!) Still take place. In most cases, the problem “BIOS does not start: what should I do?” is allowed by an elementary replacement of the CMOS battery, otherwise a comprehensive diagnostic plan is required, and only after identifying the cause of the malfunction, make a repair (correct!) algorithm of actions. details in the article!

Why the BIOS suddenly stopped starting: a little about all the reasons

Let’s get down to specifics, because the “won’t start” situation may look different:

  • When you press the “on” button, nothing happens. a black screen and silence.
  • The computer turns on, the screen flickers with a black void (no active). you hear the noise of the fans and the system speaker beeps (BIOS speaker).
  • The computing device starts, some message is displayed on the screen. the buttons do not react, except the restart works.
  • The system boots too quickly (and, safely!), But you cannot get into the BIOS.

There is another interpretation of the voiced problem, when a novice user does not correctly understand what exactly is happening and at the same time asks the question, how can I enter the BIOS at all? Let’s start with the last one

This “electronic opportunity” has a rather long list of “causes and effects”, nevertheless, it is possible to single out the main symptoms of a malfunction, namely, to identify in the shortest possible time the real culprit of the “silent celebration”.

  • With a probability of 99.9%, the power supply has failed. Naturally, replacing a component with a known good power supply unit will correct the situation towards “The problem is resolved!”.
  • The power button is out of order. replacing the switching element or checking the wire for mechanical damage (obvious breakage, deformation of the wire, oxidation of contacts, etc.), of course, with its subsequent restoration (soldering, cleaning).
  • Dust contamination of the inside of the computer case (especially important for portable computer equipment. laptop). it is necessary to clean all the components of the motherboard from dust, as well as the supplied modules and strapping equipment. Do not forget to clean the air intake grilles and other structural elements of the enclosure.

How to enter basic computer settings

Depending on the BIOS version (s), as well as the design features of the computer, access to the basic settings may be radically different from the methods that are considered standard.

For example, in most PC modifications, the BIOS is entered by pressing the “F2” or “Delete” function button. over, activation of one of these buttons is carried out directly at the time of starting the computer system at its initial stage. By the way, there is a special technique for calling the main BIOS menu. repeatedly pressing the corresponding button with an interval of two clicks per second.

There are other “tactile schemes” for entering the BIOS. some manufacturers supply their devices with special mechanisms, push-button or lever type, when activated, the user enters the service menu of the basic microsystem. However, there are also more exotic buttons. touch. However, the essence of the listed keys and service gadgets is the same. calling the BIOS Setup menu.

As for the “high-speed resistance” to the moment of entering the basic menu of computer settings, there are several options for solutions:

  • Enter the BIOS menu via Windows OS. use this link to learn how to do this.
  • Try calling BIOS using other service keys, for example, “F8”.
  • Finally, you can get into the basic settings using the rescue disk “System Restore” or a distribution kit with Windows.

Not a quick introduction: small BIOS and big consequences

Indeed, everything depends on a small microcircuit, which contains a set of microprograms in its memory, and in the aggregate is the basic microsystem of a computer! A very rare electronic ailment found in our time. damage to the main BIOS entry of the system (not to be confused with temporary data stored in CMOS memory!). this is a “dead” motherboard. That is, the motherboard becomes completely useless, since it is devoid of a triggering control element.

A partial BIOS failure of a microchip can be accompanied by an incredible number of surprises, both hardware and software. In general, the beginning of all computing beginnings is a small microcircuit with a certain set of programs. The degree of efficiency of the computer used depends on how correctly you configure the BIOS, directly affecting the overall operational life of the computing device as a whole. If for you, dear reader, all of the above has become news, then it makes sense to think: “Do I follow the manufacturer’s critical instructions regarding operating rules?”.

The computer turns on, but the monitor screen is “full of black secrets

As a rule, problems with starting a computer system are always accompanied by a specific sound signal, the tonality and sound sequence of which has its own decryption code.

To solve the described problem, you can also try to change the computer’s power supply, but to a greater extent, this “PC behavior” indicates that the BIOS has detected a faulty component in the system: one of the memory sticks (RAM) is out of order, the hard drive is broken, or the processor temperature has reached a critical level. In the latter case, it is necessary to replace the thermal paste and check the cooler of the cooling system for serviceability.

Otherwise, user actions should be as follows:

  • Disconnect all peripheral devices (printer, fax, webcam, external storage devices, etc.).
  • Remove all RAM modules.
  • Disconnect hard drives.
  • Switch to another graphics mode. change the video circuit from integrated to discrete, or switch to an integrated video chip if you used an external video card.

If an empty continent starts up, throw one at a time from the previously disconnected components and carefully monitor the reaction of the microsystem as a whole. In any case, if the BIOS starts up, then you have already achieved a positive result.!

By the way, do not forget that a black screen can be the result of a failed monitor. Laptops are often damaged by the integrity of the connecting cable, which is constantly subjected to dynamic load when opening / closing the display cover. In the latter case, it is better to contact a laptop repair service center. Both in the first and in the second case, to check the truth of the assumption, you can always try to connect an external monitor to the VGA connector.

What was installed or connected to the computer

Think about the latest changes first. Perhaps you connected a new device, cleaned your computer, installed a program, or updated drivers? These changes could have taken place without your intervention. For example, Windows 10 automatically installs system and driver updates without getting user permission.

  • If you disassembled the computer case and disconnected the devices, reconnect them again. An additional symptom indicating a hardware problem will be one or more beeps during boot.
  • Disconnect all external devices from the computer if they were recently connected. Disconnect external storage devices, printers, phones, or any other devices. Disconnect from the computer network and turn off WI-FI, this may be the cause of the failure.
  • If Windows won’t load due to recently installed programs or drivers, boot into Safe Mode and uninstall them.

If you have activated the functionality of restore points, you can roll back to the last working configuration or perform an automatic system restore.

Computer power supply

  • The most common cause of the problem with the system loading may be the lack of voltage in the network. Or, the voltage may not be sufficient to start. Check the lights on your computer or laptop after connecting to power. Frequently burnt outlets or cheap surge protectors can make poor contact with the power plug.
  • In the case of a computer, you must also check the power connection of the monitor. Some system units have an additional power switch on the rear panel. Make sure it is in the up position.
  • The reason for the lack of power may be a problem in the cable, power supply of the laptop, computer or monitor. Each power supply has a power limit. If you connect a powerful processor, video card, several hard drives to a computer with a 150 watt power supply, it will not boot. If your monitor is connected to power through the system unit, try connecting it directly.

Incorrect BIOS setup

A problem in loading the operating system can be caused by a change in the operating mode of the hard disk: IDE, AHCI. Change the BIOS operating mode: Legacy, UEFI, CMS (Compatibility Support Module).

Another reason could be choosing the wrong boot media or choosing to boot over the network. An additional symptom of this problem will be an error message with the words “No bootable device”.

Failure to update the BIOS on time or using the wrong firmware can render your computer completely inoperative and require you to reset the BIOS to default settings.

Installing multiple OS or hard drive from another computer

If you connected the disk to another computer to install the OS, or installed several systems on this computer and cannot boot one of them, use Automatic Boot Recovery. An additional symptom of this problem will be an error message with the words “no operating system found”.

What to do if Windows 10, 8, or 7 won’t boot

In this article, we will look at the reasons why the system may not boot and how to fix them. Once you turned on your computer and Windows refused to boot, don’t you know what to do? There are a lot of reasons why Windows won’t boot, let’s look at some of them. Don’t panic as modern Windows 10, 8, and 7 have many tools to help you recover from a system boot crash.

Long system boot, crash during boot

If the OS boot is interrupted in different places with different errors, or the system starts only after a few unsuccessful attempts, there is a high probability that there is a problem with the hard drive. An additional symptom may be extraneous sounds (knocking, grinding) emitted by the hard disk.

In this case, you need to urgently back up important data and replace the hard disk of your computer. You can also diagnose or repair bad disk sectors, but after creating a backup.

Laptop won’t turn on. black screen

There are many factors that can cause this problem on your computer. Therefore, before proceeding to solving the problem, you need to clearly determine what is the reason that our laptop does not turn on. If the screen does not turn on, and no indicators even light up, then the reason may turn out to be even more commonplace than one might think. Perhaps your laptop is working, but only the outlet is out of order. In this case, we will try to reconnect the laptop to a different outlet. If after this the problem remains unresolved, then the reason for not turning on the laptop may also be a damaged power cable. In this case, the solution to the problem is to buy a new cable, or we send it for repair for restoration.

The reason for the black screen can also be damage to the laptop display. For example, the display matrix, for some reason, may be damaged and not respond to switching on. But if this is really the problem, then all other parameters must necessarily function. the power-on indicators will light up, and the fans will begin to cool the system. To make sure that the reasons are in the laptop display, after starting the computer, we can simply connect the laptop to any monitor or TV using an HDMI, VGA or DVI cable. If the picture appears, then there is a 100% malfunction in the display.

BIOS problems

A person’s inquisitiveness is very great. Even if the laptop works stably and performs its basic functions, over time it becomes very interesting to us, and what is hidden in the settings of our device. If you touch a laptop, then the “holy of holies” settings of any computer are hidden in its BIOS. In the event that you do not know what BIOS is and what it is intended for, then it is better to skip this item and never change the settings in it. And if, nevertheless, it so happened that you went into the BIOS, changed something there and after that the laptop does not turn on and writes some messages at startup, then there is only one solution. it is best to reset the BIOS settings to the factory settings.

In order to reset the hardware settings of your laptop, you need to return to the BIOS (the method is individual for some manufacturers), then find the “Load Setup Default” option in it and press Enter. Then press F10 and Enter again. The laptop will reboot and reset the BIOS settings to their original settings. If the reason that the laptop did not turn on was in the BIOS, then these measures will solve the problem and you will be able to use your PC again.

Fans are making noise, but the laptop screen is not working

In the event that we start our computer, the fans are noisy, all signs of turning on the PC occur, right down to the power-on indicator lights, but the laptop screen does not turn on, then, again, there may be several reasons. The first cause of a non-working screen might be a software problem, such as the BIOS or a malfunctioning operating system. We have already considered the solutions to this problem, but, along with software problems, breakdowns of laptop components may also occur. In this case, the laptop starts up completely, but we will not see any indication of the device’s operation on the screen.

The reasons for this may be a faulty display matrix that does not work. We examined this problem a little higher and we cannot do without contacting a service center for repair. Another problem could be a faulty video card. If the image is not displayed on the screen of the device, then there must be some reason, and in laptops and desktops, in this case, the most common cause is a malfunction of the video system. And in especially difficult cases, the inability to turn on the display in a laptop during bootup causes damage to the motherboard.

What to do if your laptop won’t turn on

Despite the huge variety of gadgets that surround us every day, a laptop is still very important for us.

Almost every one of us has a laptop, and if not, then most likely you have a regular desktop at home. Today we decided to analyze a fairly common problem that can cause panic for many of us. This problem lies in the fact that at one point, we decide to turn on our laptop, and it refuses to start. There can be a huge number of possible options, but here are the most common ones.

  • We turn on our laptop, but it does not show any signs of life, the indicators do not light up, the screen remains black, coolers and other components do not turn on.
  • It also happens that we press the power button, the indicators light up, but nothing happens. The operating system does not boot, components, including cooling fans, are also silent.
  • It may be that after switching on, the indicators lit up and even the coolers began to work, but the operating system never boots.

Let’s take a look at the most common ways to solve this problem.

Turns on, shows a splash screen or writes something and hangs

Remember what happens when we turn on our laptop? The first thing we can remember, apart from the proprietary Windows screensaver, is the manufacturer’s screensaver. Before turning on, we see a splash screen with a logo from the developers, which, at times, we do not pay attention to. But sometimes it can happen that we remember for a long time the brand that developed and sold our laptop to us. This happens when, when turned on, our device simply freezes at this very logo and refuses to boot further.

At the same time, many of us can clearly understand that even in order to enter the BIOS to change or restore settings, it is necessary to wait for this logo to load. But what could be the problem if the laptop freezes at the stage of loading this screensaver and hangs? In this case, most likely your hard disk is damaged and cannot boot the system installed on it. In this case, it is best to either replace the hard drive or contact a service center to restore it.

Constantly reboots or shuts down

If we have problems of any nature with our computer, be it a laptop or a desktop, then it is very important to understand its nature. We considered options when our laptop either does not turn on at all, or shows some signs of life, but the display does not respond to switching on. But what if we start our laptop, it turns on and outwardly everything is in order, but after a while it either reboots or turns off altogether!

In this case, the most likely problem may be improper cooling of the system or processor, or even the video system. But, despite the fact that at first glance this problem looks like a hardware problem, it can also be caused by a software failure.

Writes that it is impossible to start from the boot device

What if the laptop won’t turn on and says it can’t start from the boot device? At the same time, this may turn out to be a minor problem or a headache for us. If our laptop boots from the hard drive where the operating system is installed, and in response we receive a similar message, then most likely our hard drive is not working properly.

But if we have already delved into the BIOS settings, then we could change the boot source in it, so our computer can boot from the source that is not on the PC. In this case, there may be a problem with the download. If we try to start a laptop from a USB flash drive or reinstall the system from USB, but a message appears about the impossibility of such an operation, and, most likely, the flash drive is faulty or the USB port in the computer is damaged.
