Windows System Won’t Start On Laptop

Damaged or missing HAL.Dll file

In the case when the computer turns on, but the operating system does not load in normal mode, the reason may be in damaged HAL.Dll components (a corresponding notification may be shown on the screen).

In this situation, you need to boot the system in safe mode, call the command console and write the following line in it:

  • C: \ windows \ system32 \ restore \ rstrui.Exe (then press the Enter key and restart).

RAM conflicts

Now let’s see what to do if the computer won’t boot and a blue screen appears instead. As already mentioned, this most often indicates problems with drivers and RAM. Drivers Don’t touch it yet, but let’s look at the “RAM”.

The proposed solution to the issue of if the computer does not boot is mainly designed for stationary PCs. In this situation, you should remove all memory sticks, and then insert them one by one and check the load. Perhaps one of them is the link that causes the failures. This can be observed when trims from different manufacturers are added.

windows, system, start, laptop

If the system is able to somehow boot, using the same safe mode, the “RAM” should immediately be checked with the Memtest86 utility, which will help to identify the true cause of the problems.

The computer turns on, but the operating system does not start: Possible causes and solutions to the problem

Unfortunately, sometimes you can find quite serious problems with turning on computers and starting operating systems, although at a certain moment there was NO sign of trouble. It happens that the computer does not turn on at all, but most often the computer turns on, but the operating system does not start. It is in such situations that the discussion will go on. Consider questions related to why the computer does not boot, and what to do in such situations. There are several universal solutions here.

Possible Viral Infection

Unfortunately, viruses can also cause such situations. What if my computer won’t turn on? Ways to solve this particular problem boil down to using a powerful Antivirus scanner, which could check for threats even before starting the OS itself.

Among the whole variety of antivirus software, it is worth mentioning separately disk utilities, which start directly from an optical media or USB-device, have their own boot records and even a graphical interface like Windows. One of the most powerful tools is Kaspersky Rescue Disk. Its use can guarantee almost one hundred percent detection of viruses, even those hiding in RAM.

BOOTMGR bootloader problems

It is believed that the most common problem when a computer turns on but the operating system does not start is a damaged Windows boot manager (Boot Manager). In this case, the system just writes that there is no system partition (it simply does not see the hard drive).

You can fix this problem if you start from the boot disk and go to the command line in the recovery console, to call which you should press the “R” key. Next, you must first use the check disk command, and then fix (restore) boot records.

The whole sequence looks like this:

  • Chkdsk c: / f / r;
  • Bootrec.Exe / FixMbr;
  • Bootrec.Exe / FixBoot.

After entering commands, punctuation marks are NOT put, but the enter key is pressed. If for some reason the execution of THESE commands did NOT have a positive effect, as an option, you can use a complete rewrite of the boot sector, which is performed by the Bootrec.Exe / RebuildBcd command. If the hard drive is not physically damaged, this should work, as they say, one hundred percent.

Some third-party utilities can also be used. The most suitable program seems to be a tool called MbrFix, which is included in the Hiren’s Boot CD. After calling it, for example, for Windows 7, provided that this particular system is installed, and only on one disk (there is no partitioning), the following should be written:

  • Mbrfix.Exe / drive 0 fixmbr / win7.

This saves the user from having to make changes to the boot records, and the boot will be restored.

Problems accessing the NTLDR file

When a message appears that this component is not present in the system, the boot commit is applied first, as in the previous case.

However, if the result is not achieved, you will need to copy the original file to the root of the system partition. For example, if it is a disk “C”, and the drive is “E”, the command will look like this:

  • E: \ i386 copy ntldr C: \ (after copying the system will boot without problems).

The system does not see the hard drive

Now the worst situation is when the computer does NOT boot. Causes and solutions may be related to the hard drive.

Winchester can have both software and physical problems, although sometimes this is not even the case. The problem can be completely trivial: in the BIOS settings, the priority of booting from a removable device, for example, from an optical disk, which is currently in the drive, but is NOT the system one, is set in the BIOS. It should simply be removed and reloaded.

On the other hand, another problem that the computer does NOT start (the system does not start) may be due to the damaged bootloader and the corresponding sector records. The solution to this situation will be said a little later. But in the simplest case, you can try to recover disk data using Recovery utilities.

Sometimes changing the settings of the primary input / output system BIOS also helps. Here you need to find the section related to configuring the hard drive, and in the SATA configuration parameters deactivate the use of the AHCI mode.

Finally, the hard drive can also have purely physical damage, and here you cannot do without outside interference.

The computer turns on, but the operating system does not start: reasons

Among all the possible situations when failures occur at the boot stage, there are several typical cases.

There are three options here:

  • A black screen appears;
  • BSoD blue screen occurs;
  • The operating system starts, but cannot fully boot.

In the first case, when the computer does NOT start (boot does not turn on), messages may appear on a black screen indicating physical or software problems. In the simplest case, when nothing serious is happening, the system may report that, for example, there is no keyboard (for stationary PCs). The simplest solution would be to connect it and reboot.

If the computer turns on, but the boot does not start, and instead warnings about software failures or missing files appear on a black screen, there can be many reasons for this system behavior. Among them, first of all, one can distinguish problems with the hard drive, damage to the operating system (accidental or deliberate removal of system components or registry entries), exposure to viruses, incorrect boot sector entries, RAM conflicts, etc. By the way, if a blue screen pops up, this is more related to the “RAM” or recently installed device drivers, which cause conflicts no longer in the software, but at the physical level.

What if the computer does not boot and the operating system does not start for the above reasons? There are several solutions depending on the situation. To an uninitiated user, they may seem rather complicated, but in certain situations, only they can be used to reanimate the system. Therefore, you will have to spend both time and effort.

Using the installation disc

Many users clearly underestimate the help that an installation or boot disk with a system image can provide in solving problems associated with situations when the computer turns on, but the operating system does not load.

Firstly, almost any kit includes a so-called recovery console, with which you can eliminate many software failures, and secondly, you can use the command term here. This, by the way, is the most effective method. Further it will be clear how it works.

Let’s try to start

Faced with the impossibility of loading the Windows operating system, for a start it is worth restarting the computer a couple of times, because the problem may be one-time. If that does not help, then try disconnecting the computer from the power supply for ten seconds. In this case, you need to de-energize the uninterruptible power supply, if one is connected, and if we are talking about a laptop, then remove the battery.

It also does NOT hurt to temporarily disconnect external equipment: mouse, keyboard, printer, removable disks, wireless modules, etc. If the reason lies precisely in external devices, connecting each of them in turn will help to find the culprit.

Of course, the problem can not always be solved with the simplest manipulations, which means that you will have to start analyzing the text of the error message that appeared during computer startup.

Restoring Windows 10 boot

Using the Windows 10 recovery tool, you need to open the menu of additional boot methods (pressed after turning on the computer F8) and go to the “Troubleshooting” section.

The chance to have time to press the required key (more precisely, the combination of F8 and Shift) is great if the system is installed on an MBR hard disk and the fast startup option is disabled. For fast system SSD drives, you will have to try to press quickly. well, or you will need another bootable media.

In any case, you will need Windows 10 Installation Media. In our experience, a Windows 10 rescue flash drive can often help restore your System. It is worth considering that the system image must be the same bit as Installed on your PC. In addition, if you are using a bootable USB flash drive, it must be with the FAT32 file system.

Alternatively, you can use the MS DaRT 10 (Microsoft Diagnostic and Recovery Toolset for Windows 10) download utility package. You can download it from the official Microsoft website. Windows 10 images available for download from Microsoft.

Tens launch recovery options

The Recovery Options section (Advanced Options screen) contains five subsections:

  • System Restore. When this option is selected, the standard rstrui.Exe utility is launched, the purpose of which is to roll back the system to one of the saved checkpoints.
  • System image recovery. Launches the Windows Deployment Wizard from a native OS backup.
  • Startup recovery. Fixes errors in boot files and partitions.
    Command line. Allows you to run various system utilities.
  • Go back to the previous build. Rolls back to a previously installed version of the OS in case it was updated to Windows 10.

Windows Won’t Boot? Practical advice on how to fix everything

Due to software failures or failure of SEPARATE components of the computer, Windows may stop starting altogether. CHIP will tell you how to restore the boot of the operating system.

The problem of failing to boot Windows is quite common, despite the fact that Windows 7 and Windows 10 are very reliable operating systems and rarely crash. Of course, equipment plays a huge role in this, which is very diverse for home systems, and in budget solutions has a low fault tolerance factor.

In most cases, errors in loading the OS are either to blame for the users themselves, who, for example, performed an incorrect shutdown of the PC or accidentally deleted a system file, or the hard disk on which a bad area was formed on the boot sector.

CHIP invites you to use our tips to solve the problem with Windows loading and restore system performance.

Using Windows 10 bootable media

Connect the media to your computer, reboot, set this disk first in the BIOS settings and boot from it. After downloading, select the system language. If Russian is selected, click “Next”.

Next, you will be prompted to proceed to the installation or recovery of Windows. Click System Restore. On the Select Action screen, click Troubleshoot.

Repair utilities

The reason for almost all the problems with loading Windows discussed in this article can be bad sectors of the hard disk (bad blocks). Even if, with the help of one of the manipulations discussed in the article, the operating system was brought back to life, and it does not place it to check the working condition of the hard drive.

This can be done using the free MHDD application (can be downloaded here), which can be run directly from a bootable USB flash drive. In the program menu, select from the list the channel to which the hard disk with the OS is connected, indicated its number. Then you can view the data of S.M.A.R.T, a kind of “medical record” of the hard drive (F8 key), or start scanning sectors for errors (F4 key), after allowing their correction. “Remap | ON “.

If there are a lot of problem sectors, then the procedure can take hours and even a day. Considering that bad blocks tend to be concentrated at the beginning of the hard drive, it will be easier to move the OS partition away from the problem area. an indent of 2 GB will be enough.

For this purpose, a boot disk with a free partition editor MiniTool Partition Wizard FE is suitable. In the program menu, you need to use the operation “Partition | Move / Resize “.

No boot disk found?

The appeared error message “No bootable device” and its many variations (“No Boot device found”, “Invalid boot device”, “Non system disk or disk error”, etc.) Indicates that the computer did not even start to start operating system, because it does not see the boot sector or even the hard drive.

To understand whether there is a problem at the software or hardware level, just go to the BIOS in the already familiar section “Boot device priority”. If the hard drive (HDD) is not visible among the proposed options, then the problem is hardware related. Perhaps the power or power data cable of the hard drive has come off, or the drive has completely outlived its.

If the computer normally recognizes the hard drive, the reason is programmatic and lies in the Master Boot Record (MBR). it is damaged or missing. The situation is solved very simply.

Having booted from the installation disk, it is enough to execute just one command in the recovery console:

Bootrec / fixmbr

Returning a copy of the system file

Absence in the system Some fundamental system files, primarily drivers with the SYS extension, are often found in Windows 7 and 10. The most effective way to solve the problem is to return the loss to its place by finding a copy of it on the Windows installation flash drive, borrowing it from another computer with the same OS version or simply by searching on the endless expanses of the Internet.

If you have a second computer at hand, then you will need a LiveCD with an OS to search, download and copy files, and not requiring installation, for example, Kaspersky Rescue Disk.

One of the most convenient options is the Puppy Linux operating system, which will be up and running in less than a minute. This OS includes drivers for the most common models of network cards, which means that it will NOT be difficult to access the Internet.

The exception is the system registry files: System, Software, SAM, Security and Default, which are stored in the folder “C: \ windows \ system32 \ config”. Of course, you will NOT be able to replace copies of them from another computer, so the only option is to roll back to a restore point if it was made in due time.

Bootloader may be damaged

If you see a message with the text “BOOTMGR is missing” on the screen, then the Windows boot loader is damaged or missing. To solve the problem, you need a Windows installation disc.

Burn the image to a CD or USB flash drive. The official utility from Microsoft Windows USB / DVD Download Tool will help you with this.

Reboot the PC and press the function key in the first seconds of boot to open the BIOS. In different PCs, these can be different keys, for example ESC, F2 or F6. Pressing the F8 key in Windows 10 will bring up a menu of special boot options, including in Safe Mode. If that did NOT work, hold down the Shift key on reboot.

So, if you managed to get into the BIOS, go to the “Boot device priority” section and use the “” or “PgUp” keys to designate the USB drive as the first boot device. Then boot from the Windows installation flash drive (read how to create it here) and select the “System Restore” menu item. From the list of installed operating systems (if there are several), select the one you need and click on the “Next” button.

In the appeared window of “system recovery options” we are interested in two items: “System startup recovery” and “Command line”. The first option will automatically eliminate the problem with starting the operating system, and if it fails, you will have to turn to the services of the second.

At the command prompt, type:

“Bootrec / rebuildbcd”

Press “Enter” and agree to make changes to the boot configuration data by alternately pressing the “Y” and “Enter” keys. After that, it remains only to create a new boot sector using the “Bootrec / FixBoot” command and restart the computer.

The reasons

Since the release of Windows 10, this problem has appeared much more often than on 7 or 8 versions of the OS. There are an order of magnitude more support requests and messages on specialized forums. “Windows 10 computer won’t start after upgrade.” With such headings, posts often appear on Microsoft forums and specialized resources. With the release of new updates, such messages are becoming more and more.

The problem when the system does not start after installing the Windows 10 update occurs for several reasons:

  • Impact of third-party applications;
  • Damage to the integrity of the registry and system files;
  • Incompatibility between drivers and hardware;
  • Finally, Troubled update.

I can say that the problem arising from the updated is rather rare (except for the latest October Update ’18).

System takes a long time to start

Problem: After the update, Windows 10 64/32 bit does NOT start for a long time

Reason: Conflict with third-party software Problem update.

The solution to the problem of third-party software is described in the “Black screen” option.

Try to remove the Problematic update and prevent it from being downloaded using a special utility from Microsoft.

  • To get started, open Programs and Features, through Control Panel or through Windows Settings.
  • Click on “View installed updates”.
  • Select the last update after which the problem occurred (if you do not know which one, sort by installation date and remove updates installed on the day of the error).
  • Then reboot the system.

A utility from Microsoft will help to hide the “Problematic” update. “Show or hide updates”. You can download it from this link http://download.Microsoft.com/download/F/2/2/F22D5FDB-59CD-4275-8C95-1BE17BF70B21/wushowhide.Diagcab.

  • After downloading, run the utility;
  • At the stage of selection, select “Hide updates”;
  • And then select the update that you DO NOT want to receive anymore.

But the best way is to completely disable the updated on Windows 10. How to do it, we wrote in our article “How to disable Windows 10 updates”

Windows update brings stability and fixes for bugs and bugs. But sometimes, after updating Windows 10, the system does not start. In this article, we will analyze the ways to solve this problem and tell you about the reasons for its occurrence.

If the laptop does not start, a black screen indicating it “off”, still did not light up and load, but the noise from your “iron friend” is heard. This means that you simply do not have Initialization. That is, the computer seems to turn on, gives signs of life (namely: it turns on and makes noise “cooler”), the indicators light up “caps” and inclusions and. Everything. Nothing else. The fan is spinning wildly, “a computer” hangs and does NOT move from a dead center.

What could it be? There are several reasons for this. The first is perhaps the least pleasant. Lack of “gland”. To be more precise. Processor or RAM. That is, of course, the data “spare parts” are, but are out of order. favorable reason for your own correction. Broken BIOS. In this case, you need to reinstall it and try to turn on the computer. By the way, if the laptop does not start, do not try to replace its constituent parts yourself. likely to be left without portable equipment completely.

Restart at boot time

If the laptop does not start. HP, Asus, Acer or any other (regardless of the manufacturer). During loading of the operating system, or rather, the OS constantly reboots even before you can contemplate your desktop or even words “greetings”, there are quite a few problems here. The most common. These are viral attacks. But there may be some failures and malfunctions. If this problem overtook you, then the simplest solution is. Reinstalling the operating system. Just put clean “Windows” to a formatted hard drive, and all startup problems will be resolved. Of course, if you are an amateur “dig deeper” at the root of the failure, you can try starting in safe mode and look for what exactly is the matter in order to bypass the process “demolishing Windows”.

Benefits of laptops

For starters, it might be a laptop. It is a compact device that can replace a stationary PC. This is quite convenient for those who have a lot of space in the apartment. Laptop even with the largest diagonal Takes up a small amount of desk space.

Another plus. These are opportunities. In terms of power, portable computers are NOT inferior to stationary Brothers, sometimes even surpass them. Anyway, you must agree that a laptop is more convenient and practical. We wanted to watch a movie while lying on the couch. You are welcome! I wanted to sit at the table. No problems! Quality “laptops” no worse than stationary computers. But sometimes a problem can arise. The laptop does NOT start. Let’s see why this can happen and how to deal with it.

Is there food?

Another reason why the laptop does not start. This is the lack of battery power and, as a result, the lack of power supply to the equipment. So before going to the service center, first, make sure that your outlets are in full working order. Thus, before you sound the alarm, try connecting your laptop to different power outlets in the house.

Alternatively, insert the battery into your laptop and let it recharge for a bit. The fact that power is supplied is usually indicated by a special indicator light. If it doesn’t burn. The battery is defective. But the laptop can work without it, only from the network. So DON’T panic right away.

There is sound, pictures comments

It also happens that the laptop does not start. A black screen appears immediately after you see signs of BIOS loading. With all this, the sound comes from the computer. Typical Windows boot noises and music are heard. In this case, the behavior of the computer indicates that it is highly likely that you have problems with the video card. Most likely, it is simply broken or damaged. What should be done in this case? Of course, change “spare parts”. With a great desire and appropriate skills, you can carry out this fascinating procedure yourself. Still, it’s not worth the risk. Computer malfunctions, “healed” inept hands, can lead to the death of technology finally and irrevocably.

Why does the laptop not start, what should I do? List of possible faults

So, about 8 years ago, they actively broke into the world “laptops”. They immediately began to be in active demand. Therefore, before discussing why the laptop does not start, let’s talk about the advantages of this technique.

DOES NOT start under “music

It may also happen that the laptop does NOT start, but there are still reactions to manipulations. This is already a good sign. It’s not about technology, you don’t have to buy a completely new laptop. Usually a pretty encouraging sign. Characteristic “beeping” during the first seconds of switching on.

What are they signaling? In general, there is a huge amount of literature in which all “beeps” and the reasons for their appearance in the absence of a full start of the computer. So if you turn on your portable equipment, and she you “squeaks”, there are two ways out: read a book or take it to a service center. You can also contact your friends who have already had to deal with a similar nuisance.

Viruses

So, your laptop won’t start. What to do? If you worked safely on your own “by car” for a long time, with all this, options with a lack of electricity, batteries and a malfunction of any computer hardware have already been excluded, then, most likely, the problems are caused by viruses.

Virus attacks are known to have taken place at all times of the existence of the PC. Hackers and other ill-wishers are ready to go to great lengths to obtain information and damage it. So, different “trojans” able to bring the computer to a state “white heat”, in which you will lose control of your operating system. In addition, viruses can erase information. Absolutely any. Personal files of different content are susceptible to attacks, but primarily when “disease” computer system files are affected. In this simple way, some important details of your “operating systems” can easily be wiped off the face of the earth. As a matter of fact, after important files are deleted, then the first time you restart the system, you will encounter the fact that the laptop does not start. “Black screen of death”. This is the name of the picture, when only a black screen opens before the user when the computer boots. In the best case, a cursor will appear, which you can use on the monitor.

What to do if your laptop does not start due to virus attacks? First you need to try to clean your computer from pests. This can be done using Special antivirus programs. In addition, Windows Restore can help you with this task. Asus laptop or any other does NOT start. Does not matter. Viruses DO NOT bypass any computer.

If you don’t want to once again figure out how to cure a computer system, you can simply update it. That is, reinstall. Format your hard drive and install a brand new OS. That being said, make sure you have a good antivirus program this time around. Also, be very careful when downloading certain files from the Internet. DO NOT visit questionable sites.

There is no reaction

So, let’s consider a rather rare, but very sad reason that the laptop does NOT start. You try to turn on your little one “iron friend”, and He does not react to your actions at all. That is, an absolute vacuum. No noises, sounds of switching on, Squeaks, squeals, rustling and clicks. Only silence.

If you asked yourself a question: “Laptop does not start, what to do?”. And faced with a complete lack of reaction of this technique to all your vain attempts to turn it on, then make sure that the laptop is in good condition. Of course, this will not be as easy as in the case of a stationary PC, but it is necessary to find out what is the reason “of death”. Taking the laptop to the service center. There they will definitely tell you if your “laptop“.
