Boot Legacy and EFI, Secure Boot
The most common reason that a bootable flash drive is not visible in the Boot Menu is a mismatch in the boot mode, which is supported by this flash drive in the boot mode set in the BIOS (UEFI).
Most modern computers and laptops support two boot modes: EFI and Legacy, while often only the first is enabled by default (although it happens the other way around).
If you write a USB drive for Legacy mode (Windows 7, many Live CDs), and only EFI boot is enabled in the BIOS, then such a flash drive will not be visible as a bootable one and you will NOT be able to select it in the Boot Menu.
Solutions in this situation can be as follows:
- Enable support for the desired boot mode in BIOS.
- Burn the USB flash drive differently to support the desired boot mode, if possible (for some images, especially NOT the newest ones, only Legacy boot is possible).
As for the first point, most often it is required to enable support for Legacy boot mode. This is usually done on the Boot tab in the BIOS (see How to enter the BIOS), and the item you need to enable (set to Enabled mode) may be called:
- Legacy Support, Legacy Boot
- Compatibility Support Mode (CSM)
- Sometimes this item looks like an OS selection in the BIOS. THOSE. The item name is OS, and options for item values include Windows 10 or 8 (for EFI boot) and Windows 7 or Other OS (for Legacy boot).
Additionally, when using a bootable USB flash drive that only supports Legacy booting, you should disable Secure Boot, see How to disable Secure Boot.
On the second point: if the image being written to the USB flash drive supports booting for both EFI and Legacy mode, you can SIMply write it differently, and not change the BIOS settings (however, images other than the original Windows 10, 8.1 and 8 may still require disable Secure Boot).
The easiest way to do this is using the free Rufus program. it makes it easy to choose for which type of boot the drive should be written, the main two options are MBR for computers with BIOS or UEFI-CSM (Legacy), GPT for computers with UEFI (EFI loading).
details on the program and where to download. Creating a bootable USB flash drive in Rufus.
Note: if we are talking about the original image of Windows 10 or 8.1, you can write it in the Official way, such a flash drive will support two types of boot at once, see Windows 10 bootable flash drive.
BIOS does not see bootable USB flash drive in Boot Menu. how to fix
Guides for installing Windows from a USB flash drive or just booting a computer from it include SIMple steps: install boot from a USB flash drive in BIOS (UEFI) or select a bootable USB flash drive in the Boot Menu, however, in some cases, the USB drive is not displayed.
This manual details the reasons why the BIOS does not see the bootable USB flash drive or it does not show it in the boot menu and how to fix it. See also: How to use the Boot Menu on a computer or laptop.
Additional reasons that the flash drive is not displayed in the Boot Menu and BIOS
In conclusion. some more nuances, which, in my experience, are not fully understood by novice users, which causes problems and the inability to boot from a USB flash drive in the BIOS or select it in the Boot Menu.
- In most modern BIOS versions, in order to install a boot from a USB flash drive in the settings, it must first be connected (so that it is detected by the computer). If it is disabled, it is not displayed (connect, restart the computer, enter the BIOS). Also Considering that “USB-HDD” on Some older motherboards is not a USB stick. Read more: How to set boot from a USB flash drive to BIOS.
- In order for the USB drive to be visible in the Boot Menu, it must be bootable. Sometimes users SIMply copy the ISO (the image file itself) to a USB flash drive (this does not make it bootable), sometimes they also manually copy the contents of the image to the drive (this works only for EFI boot and only for FAT32 drives). Perhaps it will be useful: The best programs for creating a bootable USB flash drive.
It seems that everything. If I remember any other features related to the topic, I will definitely add the material.
Booting from a USB stick on older computers
On older BIOS versions, it is also possible to boot from a USB stick. For example, to boot from an old Acer laptop, press the F2 key at startup. Got into the BIOS of the Acer laptop, go to the “BOOT” menu.
Next, go to “Boot Device Priority” and put your boot device in the first place.
Now after saving, your Acer laptop will boot from the flash device. This old BIOS configuration is installed on most Acer notebooks. Therefore, with other legacy Acer notebook models, the setup will be SIMilar.
USB drive for UEFI computer
If you buy a new computer or laptop now, then it will definitely support UEFI BIOS. There are many benefits to using the new UEFI BIOS, so the bootable flash drive must be UEFI capable.
If you create a bootable USB drive for Windows 7, 8.1 using MediaCreationTool, the UEFI system will support it. And with the Windows USB / DVD Download Tool for Windows 7, this option will not work.
Consider the option of creating an installation flash drive with support for UEFI systems for Windows 7. To do this, download the Rufus program on the website https://rufus.Akeo.Ie. Please insert the USB stick before starting the program. After launching the Rufus utility, select the Windows 7 image. You can do this by clicking on the DVD disc icon. The program window will look like this.
If all the points match, as shown in the figure, then feel free to press the Start button. Then the recording of files will start.
After writing the files, you can use the flash drive to install Windows on a UEFI system. Rufus can also be used for systems with a regular BIOS. A notable feature of the Rufus program is the fast speed of writing the image to the drive.
After reading this material, you can create bootable USB drives for Windows and Linux-like operating systems. And you will not have such questions as: why does the BIOS have my flash drive or why Windows does not support the UEFI system.
Configuring BIOS to boot from a USB drive
Let’s look at an example of booting a UEFI BIOS from a USB drive. For example, we will use MSI motherboard. A58M-E33, which has the latest UEFI BIOS. To enter the UEFI BIOS settings of the A58M-E33 motherboard, you must press the F11 key when starting your laptop or desktop computer. You will see a boot menu in which you need to select a flash drive, in this case it is “KingstonDataTraveler 2.0PMAP”.
You can also set in the option so that the flash drive is loaded immediately from the BIOS. To do this, press the Delete key while loading. You will be taken to the UEFI BIOS main menu.
Then go to the “Settings \ download” menu and put the flash drive in the first place, as shown in the figure below.
Your system will now boot from the selected flash device. But if your PC or laptop has UEFI and the system does not see the bootable USB flash drive, then the image is incorrectly recorded, or the “Safe boot” mode is enabled (for how to fix, see the section below “How to configure UEFI to.”).
If the BIOS does not see the bootable USB flash drive how to install
Flash drives have now become an indispensable tool for storing and transferring information to a PC. Most personal computer users use flash drives to install Windows or Ubuntu. This is due to the fact that you do not need to write the image to disk, but you need to carry out the installation directly from the flash drive.
In addition, most laptop and computer manufacturers, such as Acer and Lenovo, now make desktops and laptops without optical drives, further popularizing bootable Windows installations. When installed in this way, many laptop and desktop users have situations where the BIOS does not see the bootable USB flash drive. In this article, we will try in detail to figure out how to write an image to a USB flash drive, as well as deal with BIOS settings for the correct installation of Windows and Ubuntu.
If you are faced with the fact that when you restart your PC, your flash drive is not detected, then the first step is to make sure that the flash drive is really bootable. The fact is that just copying files onto it is not enough.
over, if you have an “absolutely working” bootable flash drive, since you have already installed the system from it many times, then we have to disappoint you: currently there are several types of boot systems and a flash drive running on one NC will not work on another. For success in this case, the system needs to be rewritten in a different way.
Therefore, the main part of the article contains detailed instructions on how to properly write a bootable USB flash drive using various software. The following article contains recommendations for configuring different types of BIOS.
Correctly creating a bootable USB stick for Ubuntu 15
For Ubuntu 15, you need to download the UNetbootin utility from https://unetbootin.Github.Io. Launched the program, you must select the options as in the picture below and click OK.
After that, downloading and writing files to the bootable flash drive will begin, in this case it is drive D.
In the final window, you will be prompted to restart your computer or laptop and boot from the USB flash drive.
Correct creation of a bootable USB flash drive for Windows
- Windows 7;
- Windows 8.1;
- Windows 10,
- Ubuntu 15.
To create a bootable USB flash drive for Windows 7, you need to download a licensed image. You can download it on the Official page www.Microsoft.com/ru-ru/software-download/windows7. To write an image to a USB flash drive, you need a proprietary Microsoft Windows USB / DVD Download Tool, which can be downloaded at www.Microsoft.com/en-us/download/windows-usb-dvd-download-tool. After installing the utility, you can start creating a bootable USB flash drive. After starting the utility, a window will appear in which you must specify where the image is located.
After clicking Next. You will be taken to the device selection window for recording an image.
In this window, click the USB device button. After which you will proceed to the selection of the flash drive.
After selecting the required USB flash drive, click the Begin copying button. The process of copying the installation files to the USB flash drive will begin. Also, be careful, as all previously stored files on the USB drive will be erased.
The inscription in the last window “Status: Backup completed” will mean that your bootable flash drive is ready.
To install Windows 8.1, you need to download the official MediaCreationTool utility at http://windows.microsoft.com/en-us/windows-8/create-reset-refresh-media. Launched the utility, you will be taken to the OS version selection window, in which you need to select the language, version and bitness of the operating system.
In the next step, you need to select a Windows recording device. In our case, this is a “USB flash drive”
The next step will give you the opportunity to choose a USB flash drive.
After that, the next step will be to download and write files to the drive. As with the previous example, all data on the flash drive will be erased.
The last window will notify you that the installation drive is ready.
To make a bootable flash drive for Windows 10, you need to download the MediaCreationTool utility from this page: www.Microsoft.com/en-us/software-download/windows10. If you run the Windows 7 or 8 utility, the program will offer you two options: update or create installation media. You need to choose the second option.
The step of creating a bootable drive will be SIMilar to the example for Windows 8.1.
How to configure UEFI so that the computer sees a bootable USB flash drive
There are some peculiarities of installing Windows 7 or XP on Windows 8 or 10 PCs. The latest versions (8 and 10) are configured for UEFI and GPT partition table, while the previous ones used MBR disk partition.
UEFI introduces a new “Safe boot” feature to ensure system boot security. New level of security blocks booting from external devices such as USB stick and CD drive.
Therefore, even if you make an exceptionally correct bootable USB flash drive, it will still NOT appear in the boot menus when you restart your PC or laptop.
To eliminate this cause, you can do the following:
- Make sure that your USB bootable flash drive is configured to work with UEFI (how to make such a USB flash drive correctly. described above).
- Disable “Safe boot”, and change “Boot Mode” to “CSM / Legacy BIOS Mode”.
Working with bootloader settings requires experience, and we do not advise beginners to perform such actions. We also recommend that you save all important data in advance, as they may be lost.
To disable Safe boot, follow these steps:
- Restart your computer or laptop and enter BIOS.
- Go to the “BIOS Settings” page.
- In the BIOS security settings, set the “Safe boot” option to “Disable”.
- Change the “Boot Mode” option to “CSM (Compability Support Mode) / Legacy BIOS” or “CSM Boot”. Possible different options.
- Make sure USB is the first in the Boot Order settings.
- Exiting BIOS with saving changes “Save and exit”.
Check if the computer sees the connected USB flash drive in “Disk Management
Start the disk management utility in one of the following ways:
- Start. Run (Win R), enter the command diskmgmt.Msc. Press Enter
- Control Panel. Administrative Tools. Computer Management. Disk Management
In the disk management window, note whether the flash drive appears and disappears when it is connected and disconnected from the computer.
Ideal. if the computer sees the connected USB flash drive and all partitions on it (usually one) are in a “good” state. In this case, it is enough to name it with the right mouse button, select “Make partition active” in the context menu, and, possibly, assign a letter to the flash drive. this will be enough for the computer to “see” the USB disk. If the section is faulty or deleted, then in the status you will see “Not allocated”. Try to name it with the right mouse button and, if such an item is found in the menu, select “Create a SIMple volume” to create a partition and format the flash drive (the data will be deleted).
If the label “Unknown” or “Not initialized” is displayed in the disk management utility for your flash drive and one partition is in the “Not allocated” state, this may mean that the flash drive is damaged and you should try data recovery (more on this later in the article). Another option is also possible. you have created partitions on a USB flash drive, which are NOT fully supported for removable media in Windows. Here the instruction can help you How to delete partitions on a USB flash drive.
How to remove drivers for all USB devices
- Turn off the computer and Disconnect all USB storage devices (and not only) (flash drives, external hard drives, card readers, webcams, etc. The mouse and keyboard can be left on, provided that they have a built-in card reader.
- Turn on your computer again.
- Download the DriveCleanup utility http://uwe-sieber.De/files/drivecleanup.Zip (compatible with Windows XP, Windows 7 and Windows 8)
- Copy the 32-bit or 64-bit version of drivecleanup.Exe (depending on your Windows version) to the C: \ Windows \ System32 folder.
- Run Command Timeline as Administrator and type drivecleanup.Exe
- You will see the process of removing all drivers and their entries in the Windows registry.
When the program finishes, restart your computer. Now, when you insert the USB flash drive, Windows will install new drivers for it.
Update 2016: It is easier to perform the operation to remove mount points for USB drives using the free USBOblivion program, as described above in the section on non-working flash drives in Windows 10 (the program will work for other versions of Windows as well).
If the flash drive does not see Windows XP
The most common situation I encountered when calling to configure and repair computers, when a computer with the Windows XP operating system installed on it did not see the USB flash drive (even if it sees other flash drives), was caused by the fact that the necessary updates were NOT installed to work with USB drives. The fact is that many organizations use Windows XP, often in the SP2 version. Updates due to restrictions on internet access or poor performance of the system administrator, and were not installed.
So, if you have Windows XP and the computer does not see the USB flash drive:
- If SP2 is installed, update to SP3 (during the update, if you have Internet Explorer 8 installed, uninstall it).
- Install all Windows XP updates, regardless of which Service Pack is used.
Here are some of the fixes for working with USB flash drives released in the Windows XP update:
- KB925196. fixed errors when the computer does not detect a connected USB flash drive or iPod.
- KB968132. Fixed bugs when, when connecting multiple USB devices in Windows XP, they ceased to function normally
- KB817900. The USB port stopped working after removing and reinserting the USB flash drive
- KB895962. USB flash drive stops working when the printer is turned off
- KB314634. the computer sees only old flash drives that were connected before and does not see new ones
- KB88740. Rundll32.Exe error when inserting or removing a USB flash drive
- KB871233. the computer does not see the USB flash drive if it has just been in sleep or hibernation mode
- KB312370 (2007). USB 2.0 Support on Windows XP
By the way, despite the fact that Windows Vista is almost never used anywhere, it should be noted that installing all updates should also be the first step when a SIMilar problem occurs.
Windows USB troubleshooter
I recommend starting with this, the safest and easiest way: recently, on the official website of Microsoft, its own utility for fixing problems with connecting USB drives, compatible with Windows 10, 8 and Windows 7, appeared.
After running the utility, all you need to do is click Next and see if the problems have been fixed. During the error correction process, the following items are checked (descriptions taken from the troubleshooter itself):
- USB device may NOT be recognized when connected via USB due to the use of high and low filters in the registry.
- USB device may NOT be recognized when connected via USB due to damaged top and bottom filters in registry.
- USB device does not print. This is most likely caused by a print failure or other problem. In such a case, you may NOT be able to disconnect the USB printer.
- I cannot remove the USB storage device using the Safely Remove Hardware function. You may receive the following error message: “Windows cannot stop Universal Volume device because it is being used by programs.” Quit running any programs that might be using this device, and then try again. “
- Windows Update is configured so that drivers are never updated. If updated for drivers is found, Windows Update cannot automatically install them. For this reason, USB device drivers may be out of date.
In case something has been fixed, you will see a message about it. It also makes sense to try reconnecting your USB drive after using the USB troubleshooter. You can download the utility from the official Microsoft website.
The computer does not see the USB flash drive. what to do?
In this manual I will describe all the ways I know to solve this problem. The most SIMple and, at the same time, the most effective methods in most situations when the computer does not see the USB flash drive, reports that the drive is NOT formatted or gives other errors. There are also separate instructions on what to do if Windows writes that the disk is write-protected, How to format a write-protected USB flash drive.
There are many reasons why you may face the fact that the computer does not see the USB flash drive. The problem can manifest itself in any version of the operating system from Microsoft. Windows 10, 8, Windows 7 or XP. If the computer does NOT recognize the connected USB flash drive, this may manifest itself in several variations
- The computer writes “insert disk” even when the flash drive was just connected
- The icon of the connected flash drive and the connection sound just appear, but the drive is NOT visible in the explorer.
- Writes what needs to be formatted, since the disk is NOT formatted
- A message appears stating that a data error has occurred
- When you insert a USB flash drive, the computer freezes
- The computer sees the USB flash drive in the system, but the BIOS (UEFI) does not see the bootable USB flash drive.
- If your computer writes that the device is NOT recognizable, you should start with this instruction: USB device is NOT recognizable in Windows
- Separate instruction: Failed to request a USB device descriptor in Windows 10 and 8 (Code 43).
If the methods that are described at the beginning will not help “cure” the problem, go to the next. until the problem with the flash drive is resolved (unless it has serious physical damage. then there is a possibility that nothing will help).
Perhaps, if the described below does not help, another article will come in handy (provided that your flash drive is not visible on any computer): Programs for repairing flash drives (Kingston, Sandisk, Silicon Power and others).
- Check your computer for viruses. they can serve as a prerequisite for inappropriate behavior of USB devices
- Check the Windows registry, namely the HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer key. If in this section you see a parameter named NoDrives, delete it and restart your computer.
- Go to the Windows registry key HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control. If the StorageDevicePolicies parameter is present, remove it.
- In some cases, a complete blackout of the computer helps. You can do this as follows: Unplug the flash drives, Turn off your computer or laptop, Unplug from the outlet (or Remove the battery if it’s a laptop), and then, while the computer is off, press and hold the power button for a few seconds. Then release it, reconnect the power supply and turn it on. Oddly enough, it can sometimes help.
Further SIMple steps
Try to go to the device manager and see if your device appears as unknown, or in the “Other devices” section (as in the screenshot). the drive may be called there by its real name or as a USB storage device.
Click on the device with the right mouse button, select Uninstall, and after deleting it in the device manager in the menu, select Action. Update hardware configuration.
Perhaps this action will already be enough for your flash drive to appear in Windows Explorer and be available.
Among other things, the following options are possible. If you connect a USB flash drive to your computer via an extension cable or USB hub, try connecting directly. Try plugging into all available USB ports. Try turning off your computer, disconnecting all extraneous devices from USB (webcams, external hard drives, card readers, printer), leaving only the keyboard, mouse and USB flash drive, then turning on the computer. If after that the flash drive works, then the problem is in the power supply to the USB ports of the computer. perhaps there is not enough power from the PC power supply. A possible solution is to replace the power supply or purchase a USB hub with its own power supply.
Windows 10 does not see a USB flash drive after updating or installing (it will work for Windows 7, 8 and Windows 10)
In this case, the free USBOblivion utility can help, which removes from the Windows registry all information about previously connected flash drives and external hard drives. Before implementing the program, I recommend creating a Windows 10 restore point.
Disconnect all flash drives and other USB storage devices from the computer, run the program, Check out the Perform a real cleanup and Save the undo reg file, then click the Cleanup button.
After cleaning is complete, restart your computer and connect the USB flash drive. with a high probability, it will be detected and become available. If there is, then try also to go to the device manager (through the right click on the Start button) and Follow the steps to remove the USB drive from the Other devices section and then update the hardware configuration (described above). You can download the USBOblivion program from the Official developer page: www.Cherubicsoft.com/projects/usboblivion
But, in relation to Windows 10, another option is also possible. Actual incompatibility of USB 2.0 or 3.0 drivers (as a rule, then they are displayed with an exclamation mark in the device manager). In this case, the recommendation is to check the availability of the required USB drivers and chipset on the official website of the laptop or PC motherboard manufacturer. At the same time, I recommend using the official sites of the manufacturers of the devices themselves, and not the sites of Intel or AMD to find such drivers, especially when it comes to laptops. Also, sometimes updating the BIOS of the motherboard helps to solve the problem.
Reinstalling USB devices in Windows Device Manager
If none of the above has helped yet, and the computer does not see any flash drives at all, and not just one specific one, you can try the following method:
- Go to Device Manager by pressing WinR keys and entering devmgmt.Msc
- In Device Manager, open the USB Controllers section
- Remove (right click) all devices named USB Root Hub, USB Host Controller or Generic USB Hub.
- In Device Manager, select Actions. Update Hardware Configuration from the menu.
After reinstalling USB devices, check if the USB drives on your computer or laptop are working.
How to use DMDE
Solving the problem using the USBOblivion utility
The Windows registry may contain old information about USB flash drives previously connected to the PC. Due to this information, when connecting a new drive, a conflict may arise in the system. In this situation, cleaning of these records is required. The third-party application USBOblivion will help in this case. It can be used if the problem appeared after installing the updated “operating system”. Let’s move on to specific steps:
- We go to this official resource of the utility and click on the button with the underlined Download arrow. Click on Download to download the program archive
- We unpack the archive into a folder with the rest of the PC programs and run the file corresponding to the bitness of your system. In our case, the system is 64-bit. Open the file with the bitness that is on your system
- We take out all the flash drives from the USB connectors. We put a checkmark next to all the items at the very bottom of the window, including real cleaning, saving the undo file for the registry and restarting the “operating system”. Click on “Cleanup”. Check all the items below and click on “Cleanup”
- Allowing junk makes changes to your system. Click on “Yes” to allow the application to make changes to the system
- First, the program will create a restore point on your PC and close the “Explorer”, and then it will start cleaning the registry from unnecessary files associated with USB connectors. We are waiting for the completion of the procedure. The program will first create a restore point on your system
- When the item “Completed” is displayed, and the “Cleanup” button becomes clickable again, this will mean that the program has finished the cleaning procedure. We click on “Exit”, connect and check the USB flash drive. When the “Cleanup” button becomes clickable again, it means that verification and cleaning is complete
How to work with USBOblivion
If the reason is a conflict of names of several devices
If you hear the usual operating system signal when connecting a USB flash drive and see that there is a USB icon in the Windows tray, but the USB flash drive does not appear in Explorer, there may have been a name conflict for several devices (the same letters are set for them). To remedy the situation, follow these steps:
- Launch the Run menu using R and Win and write the key diskmgmt.Msc. click on OK to execute the code. In the Run window, run the command diskmgmt.Msc
- Find your problem drive in the Disk Management interface. If you can’t find it right away, pull the drive out of the slot and reinsert it into the slot. And the line that first disappeared after disconnecting and then reappeared corresponds to the USB flash drive. Recognize its condition right away. the fourth column should contain the value “correct”. Only in this case, we proceed to further actions. Find your drive in the list and make sure it works
- Right-click on the flash drive and look at the context menu. Perhaps your USB drive was SIMply put into a passive state for some unknown reason. In this case, the action “Make this section active” will be clickable. just click on it and check access to the flash drive. If the option is not clickable (pale shade), click on the next line “Change letter”. Go to change the letter of the carrier
- In the small window, click on “Change”. Under the field, click on the “Change” button
- In the next dialog box, Expand the list with letters and put the symbol that has NOT yet been used for any disk or other drive on this PC. Click on OK. Select a new drive letter from the drop-down menu
- Removing and then reinserting the USB flash drive and looking at the result.
Automatic diagnostics and fixing problems with flash drives through a utility from Microsoft
The situation can be corrected by a special application from Microsoft for troubleshooting various problems related to flash drives and USB outputs:
- We follow this link, which leads to the official Microsoft page for downloading the required utility. Click on the blue “Download” button and open the file through the download panel in the browser or using the “Explorer”. Download a tool to diagnose problems with flash drives on the Microsoft website
- Click on “Next” in the lower right corner of the utility to start diagnostics. Click on “Next” to start the diagnostic process
- We are waiting for the completion of the procedure. it will take some time. Wait for the system to find problems and try to fix them
- As a result, we get a report after the search. A tool to list the problems found. In order for the tool to try to solve them on its own, you need to name the fault by the link and, if necessary, perform one or another of the steps described in the wizard. If no problems are identified, the phrase “Element is missing” will appear opposite the items. Here we just click on “Close” and move on to other methods. Review Diagnostic Tool Reports After Verification
Insert disc message
After connecting the flash drive and PC, the message “Insert disc” may appear on the display. What if the media is already inserted? A notification in the dialog box appears if there is a conflict of drivers. try reinstalling them first in the “Device Manager” (the procedure is described in detail in the section on outdated “firewood”. the “Update configuration” option).
Insert disc message appears if there is a driver conflict
If that doesn’t work, remove all USB device drivers using DriveCleanup, which you can download from this official developer site. When you do the cleaning, just insert the USB flash drive again. its driver should automatically install.
Use DriveCleanup to completely remove USB drivers from your device
Such an error may also be due to a problem with the port. try inserting the USB flash drive into a different connector. If the situation is the same, then the matter is still in the drivers.
If drivers are missing or out of date
If the flash drive does NOT appear in Explorer at all, try to update the flash drive drivers. through the standard system window “Device Manager” or third-party utilities. We’ll cover the first method:
- Right-click on the “Start” icon and select the dispatcher. You can also quickly launch its window through the “Search” panel. Click on “Device Manager” in the context menu of the “Start” key
- The item for a flash drive is in one of three menus: “Other devices”, “USB controllers” or “Disk devices”. We found the USB stick in the last section. It’s easy to recognize your drive. the line will contain the name of its manufacturer. We have Transcend. Find in one of the lists the item dedicated to the hardware of your flash drive
- Right-click on the line with the flash drive hardware and launch the update in the context menu. Click on “Update Driver”
- We select automatic update from the extended wizard window. Run automatic search and installation of driver updates
- We are waiting for the search for available upgrade files on the network to complete. If there are any, the dispatcher will immediately download and install them. Wait while the built-in tool tries to find an available driver update on the network
- If the updated on official sources is not available, a notification will appear about the relevance of the current flash drive drivers. Click on “Close”. You may see a message stating that the current drivers are already installed
- Let’s try another update method. right-click again on the flash drive in the manager and select delete. I confirm that we want to remove the device. The drive will disappear from the list almost immediately. Confirm the delete action in the gray box
- DO NOT take out the USB flash drive, click on the menu with a list of actions and click to start updating the PC configuration. Our media will appear in the list again. You can also just take out and reconnect the USB flash drive. it should automatically install its drivers in the system. Open “Explorer” and check if the content is available. After uninstall, update the configuration of all hardware
If the problem persists, you may need to update the “firewood” for all USB chipsets. If you still have a driver disc that came with the motherboard, use it. If there is no such tool, download the upgrade from the official website of the manufacturer of either the motherboard or the PC itself. You can also use a special third-party utility to update the system drivers, for example, the DriverPack application.
Recovering data from a flash drive that the computer does not see
If in the “Disk Management” window your flash drive is in the “Not recognized”, “Not initialized” state, and the section “Not allocated” itself, this means that the data on the drive has been damaged. Even if the drive itself is displayed, but its contents are not, this does NOT mean that the files have completely disappeared from the flash drive. You can try to recover files. Such third-party free utilities will help with this:
- DMDE. repairs efficiently and does not require installation.
- HDD Raw Copy Tool. makes sector-by-sector analysis and a copy of the media.
- Virtual CloneDrive. creates an image in img format, suitable even for drives with a size of 500 GB or more.
- Recuva is more suitable for recovering photos, audio and materials. Unfortunately, she cannot handle text documents and installers.
- Photorec. uses atypical aLGorithms, restores not only photos, but also other types of files.
If none of the utilities has restored your files, Contact the PC repair service center. specialists there are professionally involved in recovering files from drives. Maybe they can help you.
