Causes of the problem
One of the most common reasons why the BIOS does not see the usb flash drive is the wrong Boot Mode.
Modern laptops and personal computers have two modes: UEFI and Legacy. As a rule, the first mode is activated by default. If the bootable flash drive was written for the second mode, which is currently disabled, then you will see this error.
The second reason why the BIOS does not see USB is an incorrectly written installation flash drive. The fact is that many users write the Windows installer to a USB flash drive, just copy the ISO image. You can’t do that. Thus, you will NOT make the USB flash drive bootable. Even worse is when files are SIMply copied to a USB flash drive.
Activating the correct boot mode
If everything is clear with the Incorrect recording of the bootable flash drive, then setting the correct boot mode may be an unfamiliar procedure for many. Let’s take a concrete example to figure out how to change the boot mode.
Today you can find at least three types of BIOS. And do not look at whether you have an old BIOS or a new one, the menu items may differ from those that will be indicated below, however they always have approximately SIMilar names and nestings.
If the BIOS does not see files on the flash drive, then you can change the boot mode as follows:
- Open the BIOS (restart the computer and press the “Delete” key during its restart).
- Find and open the “BOOT” tab.
- Find the “Boot List Option” and change its value to the opposite.
- Exiting BIOS, applying changes made.
BIOS does not see a bootable USB flash drive: what to do
Today we will look at:
Today, Windows installation is most often carried out with the introduction of specially prepared flash drives, which have almost completely replaced optical disks. The process of installing the operating system itself is NOT anything complicated, but it often happens that the old BIOS does not see the bootable USB flash drive.
In this topic, we will tell you what reasons can lead to this malfunction and what to do if the BIOS does not see the USB flash drive.
Disable Secure Boot
It may be that the boot drive you are using only supports Legacy mode. In this case, it may be that the BIOS does not see the usb flash drive due to the enabled Secure Boot mode.
To find out if this mode is enabled, open the search window by pressing the WinR keys, and then enter MSInfo32. In the corresponding windows you can read whether this function is enabled or disabled.
Disabling Secure Boot is very SIMple. Below is an example for Asus laptops:
- Enter BIOS.
- Open the “Boot” tab.
- Find the “Secure Boot” field and click on it.
- Set the “OS Type” to “Other OS”.
If you have an HP laptop, then this mode is deactivated a little differently: in the BIOS you need to go to the “System Conficuration” tab, where you can disable this option.
We hope our material helped you figure out what to do if the BIOS does not see the USB flash drive and why this can happen. Leave your questions on this topic below, and we will help you quickly solve them.
Why the laptop does not see the bootable USB flash drive?
Usually, with the correct connection of removable media, users do not have problems, and the equipment functions normally. However, in some cases, the laptop may SIMply not recognize the connected equipment. In this case, it is worthwhile to carefully diagnose the system and find out the source of the malfunction. Most often, problems can occur for the following reasons:
- Using the wrong drive format. It is worthwhile to clarify the compatibility when choosing and buying in advance; if necessary, you can purchase a special adapter for pairing equipment. But, as a rule, there are no problems in Windows.
- Mechanical damage to the flash drive as a result of shock or water ingress. If the integrity of internal components is violated, removable media will not be recognized by the system.
- Malfunctions in the computer’s operating system can disable some of the capabilities, including recognition of connected equipment.
- Defeat software by virus applications when downloading files from unofficial sources.
- System BIOS failure can also disable detection.
- Incorrect user settings. In some cases, the human factor may serve as a prerequisite.
Try to troubleshoot yourself if possible. Often the problem is solved by restarting the computer and closing unnecessary programs.
Important! If the problem cannot be identified, or it is too complex, it is worth contacting a specialized service center for help. DO NOT throw away the warranty, it will provide you with free help in diagnostics and troubleshooting.
The laptop does not see the bootable USB flash drive
The main use of computer technology is to process, store and move information in various formats. Over time, data becomes more and more, so special media are being developed for storing them. One of these devices is a USB flash drive, which provides fast storage and the ability to move data from various equipment.
How to view a USB flash drive if the laptop does not see it?
If you are faced with a situation where the laptop does not recognize the USB flash drive, you should read the instructions and re-tune the work, and then reboot the system. If this does not help, you can refer to the BIOS settings. To do this, you need to use the following plan and perform SIMple manipulations:
- Unplug your laptop or enable it to restart.
- When the main boot menu and a sound signal appear on the screen, press the F10, F9, Del key (depending on the device model) to enter BIOS.
- Find the “boot method” among the proposed options.
- Use the arrows to select this section and activate the value “load from flash drive”. In this case, all files and documents stored on the media will be loaded automatically.
- Open the desktop, go to the menu and operation parameters, make sure the connection is correct and check the quality and ability of various functions.
There are other ways to view data from external media. For example, you can download data to disk using a special program through a computer, and then open all data on a laptop.
Important! In some cases, it is necessary to install special applications to restore work. If the data was not valuable, buy a new drive or Change its format by transferring the information to another computer electronically.
For fast and comfortable work and loading various data, use the following tips:
- DO NOT use a USB flash drive without antivirus enabled.
- Do not trust the drive to unauthorized persons, each technique must have one user.
- Delete unnecessary databases periodically.
- Monitor the equipment condition, perform preventive diagnostics, cleaning and troubleshooting.
Before contacting a service center for port repairs or purchasing a new flash drive, there are several software-based troubleshooting methods to try. You should start with the BIOS:
- Reboot your laptop.
- When the system starts, start pressing Delete to enter the BIOS (maybe another key, look for your laptop model).
- Find the item “USB Configuration” (usually found in the “Advanced” section, but the names may be different).
- Check the “USB Controller” parameter. It must have the status “Enabled”.
- Press F10 to close the BIOS, saving the new configuration.
If you can’t find the options you want, try resetting the BIOS to factory settings. by default, the USB controller is enabled. To reset, go to the “Exit” section and select “Load Setup Defaults”.
The laptop does not see the USB stick. DOES NOT read or open. Why
If the laptop does not see the USB flash drive, then the first thing you need to do is determine the source of the problem. If the USB flash drive is not detected on another laptop, then the problem is in the drive itself. If the laptop does not detect any removable drives, then the problem is clearly in it. In both cases, the reasons can be both hardware and software in nature:
- Incorrectly installed USB drivers.
- Software glitch.
- Mechanical damage.
7 (812) 953-94-11, 7 (921) 984-75-12 (Kamennoostrovsky prospect, 42, Petrogradskaya)
The most unpleasant thing is mechanical damage. If the flash drive is not readable on any computer, and the software methods for correcting the error DO NOT help, it is possible that the plug contact has come off or the controller is damaged. A SIMilar problem can Nastich and the USB port of the laptop: if He does not find any connected devices, it is better to take him to the specialists.
Regarding the USB port, there is one more point: if you connect several devices at the same time (Using a USB hub), then the laptop’s power supply may not have enough power. Try disconnecting all devices and connecting only the USB flash drive. sometimes it helps.
Device Manager and Disk Management
If the USB settings are correct in the BIOS, but the laptop still DOES NOT read the USB flash drive, you can try working with the storage device drivers. When you first connect a drive (this also applies to a camera flash drive), its drivers are installed in the system. If the media is not ejected correctly, the next connection may fail. To fix it:
- Open the “Management” tool by right-clicking on the “Computer” icon.
- Go to “Device Manager”.
After rebooting and reconnecting the flash drive, the mass storage drivers will be installed again. Check additionally in the “Device Manager” item “Disk devices”. If you see your drive when you open it, but the Ego conductor does not open, then you can try to eliminate this error as follows:
- Click WinR.
- Write “diskmgmt.Msc”.
- Find the USB drive (if it appears in the “Device Manager”, then it should be here too).
- Right-click on it and select the “Make active” function.
If the partition is already active, try replacing the drive letter. Right-click on the drive again and select “Change letter”. Specify access by a different letter and save changes.
Changing the file system
What if none of the above helps? Check the file system of the flash drive. If it is FAT32, then problems with detection may be related to file system conflicts. To eliminate this factor, you need to format the media to NTFS. Unfortunately, if the laptop does not see the USB flash drive at all, then it will NOT work to change the file system, so the method is suitable only if the drive is detected, but the information from it cannot be read.
- Run Command Term (Administrator rights required).
- Enter the command like “convert drive_letter: / fs: ntfs” (no quotes needed).
This command allows you to change the file system without formatting, that is, deleting data. But this only works when converting from FAT32 to NTFS. However, if you are using Windows, then this is exactly the change you need.
If software troubleshooting methods do not help, then the cause should be looked for in mechanical damage to the flash drive or laptop connector. It is not recommended to try to repair the device yourself. it is safer to immediately contact the service.
What to do if the laptop does not see the USB flash drive
Before contacting a workshop for repairing a connector or purchasing a new USB flash drive, you can try several ways to programmatically correct the error. You need to start with the BIOS:
- Restart your laptop;
- During system boot, press Del to enter BIOS (sometimes another button, you need to look for a specific model);
- Look for the “USB-Configuration” menu (usually located under “Advanced”, but the names are often different)
- Find out the status of the “USB-Controller”. This item must be included;
- Save and exit BIOS.
If you cannot find the required parameters, you can try resetting the BIOS to factory settings. the external connection controller is active by default. To do this, enter the “Exit” menu and find “Load Setup Defaults”.
How to find the reason
If the laptop does not recognize the USB flash drive, then first you need to find out the cause of the problem. If the USB drive is NOT recognized on another computer, then the reason is directly in the USB drive. If the laptop does not see any external drives, then the reason is definitely in it. One way or another, the breakdowns are of a software or hardware nature.
If the storage device is NOT readable on any laptop, and software recovery methods DO NOT correct errors, then most likely the plug contact is loose or the integrity of the controller is broken. The same malfunction may appear in the USB connector of a laptop: if it does not see any external devices, the only correct solution is to contact a specialist.
Regarding the USB connector, there is one more nuance: if several devices are connected at once (using a HUB), then the laptop’s power supply sometimes lacks power. Disconnect all devices and insert only one drive. in some cases this helps.
Disk Management and Task Manager
If the USB settings are correct in the BIOS, but the laptop still DOES NOT recognize the media, try to fix the drivers of the USB flash drive you are using. When the storage device is connected for the first time, the OS installs the Appropriate Drivers. If the equipment is not removed correctly, during further operation, malfunctions are possible. To install the driver:
- Go to the “Management” menu, clicked on the “Computer” icon;
- Open the “Device Manager”;
- Select “USB Controller”.
- Remove device from the list.
After restarting and connecting the drive, the driver will be reinstalled. This can be checked in Device Manager by opening Devices. If the equipment is in the list but cannot be opened by Explorer, you can try to fix the error like this:
- Use the WinR button combination to open Run;
- Enter diskmgmt.Msc;
- Find the USB flash drive (if it is in the “Device Manager”, then this menu should also be present)
- Right click on the icon and find the item “Activate”.
If the partition is still inactive, replace the drive letter. Right click on the storage device again and find “Change letter”. Install another and save.
Why the laptop does not see the USB flash drive
The most common storage device problems:
- Flash drives not formatted.
- Dirty USB port.
- Autorunner viruses.
- Operating system crash.
- Insufficient voltage in the network.
- The USB connector is turned off or burned out.
- Difficulty with sections.
- Incompatibility of different file systems.
- Incorrect driver installation.
- Mechanical damage.
The laptop does not see the USB flash drive
Flash drives are the undisputed favorites among storage devices. But problems with their use are encountered regardless of the manufacturer and the installed version of the operating system. As a rule, this is expressed in the fact that the laptop does not see the USB flash drive.
File system setup
If none of the above works, check the media file system. If FAT32 is installed, then the malfunctions are associated with the presence of different file systems. You can fix this problem by formatting the storage device to NTFS. But, if the computer does NOT recognize the hardware at all, then it will NOT work to change the file system, so this option is only suitable if the device is detected, but the data cannot be read.
- Open the Run menu;
- On the command line write convert drive letter: / fs: ntfs.
This will allow you to install the file system without using formatting, that is, it will save the information. But this will only work when you switch to NTFS. But, if using Windows. Then this change is required.
If the software ways to fix the error DO NOT help, then the reason is mechanical failure. It is NOT advised to try to repair the equipment yourself. it is best to immediately contact the specialists.
AMI BIOS setup
The key combinations for entering AMI BIOS are the same as for Award BIOS.
If you have an AMI BIOS, follow these SIMple steps:
Go to BIOS and find the “Advanced” sector.
Go to the “Boot” tab and select the “Hard Disk Drives” section.
Move the item “Patriot Memory” to its place (“1st Drive”).
The result of your actions in this section should look like this.
In the “Boot” section, go to “Boot Device Priority” and check. “1st Boot Device” should exactly match the result that was obtained in the previous step.
If everything is done correctly, go to the “Exit” tab. Press “F10” and in the window that appears. enter.
Award BIOS setup
To enter Award BIOS, press F8 while the operating system boots. This is the most common option. There are also the following entry combinations:
- Reset (for Dell computers)
Now let’s talk about how to properly configure the BIOS. In most cases, this is exactly the problem. If you have an Award BIOS, do this:
- Go to BIOS.
- From the main menu, use the arrows on the keyboard to go to the “Integrated Peripherals” section.
Check that the switches of the USB controllers are in the “Enabled” position, if necessary, switch yourself.
Go to the “Advanced” section from the main page and find the item “Hard Disk Boot Priority”. It looks like the one shown in the photo below. Pressing “” on the keyboard, move to the very top “USB-HDD”.
As a result, everything should look as shown in the photo below.
Switching back to the main window of the “Advanced” section and set the “First Boot Device” switch to “USB-HDD”.
Return to the main window of your BIOS settings and press “F10”. Confirm the selection with the “Y” key on the keyboard.
BIOS does not see the bootable USB flash drive: how to fix
In general, there is nothing better for installing the OS on your computer than a self-made bootable USB flash drive. You will be 100% sure of it. In some cases, it turns out that the media itself is made incorrectly. Therefore, we will look at several ways how to make it for the most popular versions of Windows.
In addition, you need to set the correct parameters in the BIOS itself. Sometimes this may be the reason for the absence of a drive in the list of drives. Therefore, after we figure out how to create a USB flash drive, we will consider three more ways to configure the most common BIOS versions.
What to do if the BIOS does not see the bootable USB flash drive
Modern laptops are getting rid of CD / DVD drives one by one, becoming thinner and lighter. Together with this, a new need arises for users. the ability to install an OS from a flash drive. However, even with a bootable USB stick, not everything can go as smoothly as we would like. Microsoft specialists have always liked to throw interesting tasks for their users. One of them is that the BIOS may SIMply not see the media. The problem can be solved with a few consecutive actions, which we will now describe.
USB flash drive with Windows 7 installer
In this case, we will Use Windows USB / DVD Download Tool.
- First, head over to Microsoft and download the utility from there to create a bootable flash drive.
- Install it and start making a flash drive.
- Using the “Browse” button, which will open Explorer, specify the location where the ISO image of the OS is located. Click on “Next” and proceed to the next step.
In the window with the choice of the type of installation media, specify “USB device”.
Next, the process of creating a drive will begin.
This method is suitable for Windows 7 and later. To write images of the second systems, use our instructions for creating bootable flash drives.
In the following instructions, you can see ways to create the same drive, but not with Windows, but with other operating systems.
Logging into UEFI is the same as entering BIOS.
This advanced version of the BIOS has a graphical interface and can be operated with the mouse. To set the boot from removable media there, follow a series of SIMple steps, namely:
On the main window, immediately select the “Settings” section.
In the selected section with the mouse, set the “Boot Option # 1” parameter so that it shows the USB flash drive.
Now, Armed with a properly done bootable USB stick and knowledge of BIOS settings, you can avoid unnecessary worries when installing a new operating system.
