What Causes Unmountable Boot Volume Windows 10 Error?

Before we get into the solution, let’s define the unmountable boot volume error in Windows and how it occurs.

The boot volume is a hard disc partition that holds the boot data as well as the Windows operating system.

If you get the “Unmountable boot volume” error, you won’t be able to enter Windows and will be stuck in a blue screen of death (BSOD).

This problem occurs when your computer’s operating system fails to load correctly, resulting in a blue screen of death (BSOD).

The unmountable boot volume in Windows is an example of a “stop code,” which is a specific error message that identifies the issue encountered by Windows.

The following are some of the most common causes of the Unmountable boot volume error.

Major Windows 10 Update: The error is frequently encountered after installing a major Windows update.

Allowing a major Windows 10 update to install, according to some users, causes the “Unmountable boot volume” problem.

Corrupted system files: The most common causes are a corrupted file system or corrupted Windows files.

When one of the files that keep your system running is damaged, it can lead to several issues.

One of these problems is the inability to boot into Windows, which causes the error “Unmountable boot volume”.

Malware, human error, or a program could all be to blame for the corruption.

Wrong BIOS settings: While an incorrectly set BIOS could cause this error, it’s uncommon unless you’ve updated the BIOS yourself.

Some computer professionals enjoy tinkering with the BIOS feature in Windows. However, if you don’t know what you’re doing, this could go wrong.

Hard Disk and RAM failure: Fortunately, this error message does not always indicate that your hard disc is failing.

How to Fix Unmountable Boot Volume Errors?

As previously stated, you will not be able to debug this issue in the same way that you would debug other, minor issues.

Fortunately, there are solutions to this problem, which are detailed below. Now we’ve looked at some of the possible causes, it’s time to get down to action and start debugging.

Unmountable boot volume Windows 11 or Windows 10 errors can be resolved by attempting any of the available solutions, ranging from restarting the computer to reinstalling Windows.

There are more solutions than causes to this problem, so you’re bound to find one that works.

By following our instructions, you can resolve the “Unmountable boot volume” issue on your Windows 10 or 11 machine.

1. Restart Your Computer

Restarting a computer will resolve all minor issues with a device on any operating system. As a result, we must try that instance in this case as well.

Like other blue screen warnings, the unmountable boot volume issue is usually not a cause for concern if it occurs only once. Windows will occasionally experience some short-term glitches that will never cause you to panic.

If you get a blue screen with an unmountable boot volume error while working, restart your computer and try again.

The system can detect temporary issues and immediately repair your computer the next time you boot it up. You should be clear if the problem does not reappear.

2. Boot PC in Safe Mode

If restarting the computer does not resolve the issue, the next step in fixing the Unmountable Boot Volume error is to attempt to boot the computer in Safe Mode.

By rebooting your computer and holding down the F8 key repeatedly until the Advanced Boot Options box shows in Windows 10, you can go to Safe Mode.

Holding down the Shift key while selecting the Restart option in Windows 11 will launch Safe Mode. Once in Safe Mode, verify that your machine has properly booted.

3. Boot from Windows Installation Disc

In this step, we’re attempting to boot the PC from the Windows installation media USB because we can’t start Windows normally.

We are hoping you have the same USB. Otherwise, you’ll have to use a different PC to create a Windows installation on a USB drive or DVD.

You’ll be able to use Windows diagnostic tools if you boot from a separate device. Keeping a boot drive is always a good idea.

Windows 10 installation media is required to repair installation files or to perform a clean reinstallation of Windows 10.

Fortunately, the Windows 10 Media Creation Tool simplifies the process of creating Windows 10 installation media. Similarly, the Windows 11 Media Creation Tool is available.

Connect your installation media to your computer and boot from the USB or DVD after you’ve finished creating it.

To accomplish this, you’ll most likely need to change the boot order on your computer, which you can do in the BIOS/UEFI settings.

This Windows installation media is required to complete the other troubleshooting steps listed below.

4. Use the Windows Automatic Repair Feature

Allow Windows to begin booting from the USB drive. The Install Now screen will be displayed.

If you don’t want to reinstall Windows, choose to Repair your Computer in the bottom-left corner. You can use a Windows 10 installation disc to gain access to a variety of repair tools here.

On the next screen, select Troubleshoot to see a list of Advanced Options. Select Startup Repair and Windows 10 as the target operating system (or Windows 11).

Windows will then perform an automated repair, which should resolve your issue. After the installation is complete, exit the installation media and try to restart your computer normally.

If Windows still displays an unmountable boot volume error, proceed to the next step.

5. The Master Boot Record or GPT Repair

The Master Boot Record (MBR) or GPT stores information about the location on your hard disc where Windows is installed and aids in its proper startup.

An unmountable boot volume warning may appear if MBR becomes corrupted. Simply restoring the master boot record will resolve the “Unmountable boot volume” problem.

All you need is a copy of the Windows installation disc and follow the instructions below.

To repair the MBR, reboot from your Windows 10 installation USB and select Repair your computer > Troubleshoot.

On the Advanced Options window, select Command Prompt. To repair the MBR, type the following command into the Command Prompt:

bootrec /fixmbr

Wait for it to finish before attempting the following instructions one at a time to try additional repairs.:

bootrec /fixboot

bootrec /scanos

Wait for this command to finish before entering the next command.

bootrec /rebuildbcd

To exit the Command Prompt, type exit, and press Enter, followed by a restart of your computer.

6. Execute the CHKDSK Command

If the automated repair and MBR repair did not solve your problem, you should run chkdsk.

This useful Command Prompt application allows you to inspect your hard drive for issues that may be causing the unmountable boot volume warning.

To open a Command Prompt from the recovery menu, follow the steps outlined above by booting from the Windows installation media, then enter the following command:

chkdsk /r c:

The /r flag locates and repairs any bad sectors on your hard drive. If you leave this field blank, Chkdsk will only report any problems it finds.

For the procedure to scan your Windows disc, you must furnish C: (the most common location for it). Replace C: with D: or another letter if you have a different drive name.

When the system reboots, chkdsk may prompt you to run it again. If it does, press Y to confirm and restart the computer.

You might have to wait a while because this takes time. When it’s finished, reboot to see if the problem has been resolved.

7. Perform an SFC Scan

Another important utility that can be used as a last-ditch Command Prompt solution SFC, or System File Checker, looks for and attempts to repair corrupted Windows system files.

If none of the other suggestions have worked, this is worth a shot. Return to the Command Prompt on your recovery drive and enter the following command:

sfc /scannow

Wait for the procedure to complete. It will notify you if anything has been resolved.

After it completes, reboot and try to load Windows again, just as we did with the other commands.

8. Check the Hardware Parts

If you’ve followed all the steps above and still get an unmountable boot volume error every time you boot up, your problem is more serious.

You have two more options for a solution.

To begin, there’s a chance you’re dealing with a hardware issue. Your storage disc may have become corrupted, is failing, or has a faulty connection.

If you’re certain, open your computer (a desktop is easier than a laptop) and double-check that the hard drive connection is securely connected. Check to see if there is any clicking noise.

This issue could also be caused by faulty RAM, so make sure it’s properly installed.

Whether or not the connections appear to be in good working order, you should run some motherboard diagnostic tests to see if a component is malfunctioning.

Replacing it should solve your problem, but if you are unable to change the components yourself, you will need to seek the assistance of a computer specialist.

9. Uninstall Previous Windows Updates

If you encounter the “Unmountable Boot Volume” problem after installing an incremental or feature update, you can undo it.

Select Uninstall Updates from the Windows Recovery Environment. Then, to uninstall the most recent quality update and roll back the most recent incremental update, select Uninstall the most recent quality update.

If that fails, select Uninstall the most recent feature update to remove the most recent major Windows 10 feature upgrade.

You can use Windows System Restore and System Image Recovery options to restore your machine to a previous state.

You’ll need a previous restore point or a system image backup to use them.

10. Reinstall Windows 10

After you’ve ruled out hardware, your Windows installation may be corrupted in a way that the aforementioned methods can’t repair.

In this case, reinstalling Windows is your only option. This is inconvenient and time-consuming, but it is mitigated by having a backup.

As we did in the previous steps, boot the computer from the installation drive and select the Install Now option.

To perform a clean installation of Windows 10, follow the on-screen instructions.

Conclusion

We’ve discussed a few options for dealing with an unmountable boot volume stop code in Windows 10 and 11.

Your computer’s ability to run Windows 10 or 11 can be seriously hampered by the Unmountable Boot Volume problem.

You can successfully fix this error and get access back to your machine by using the troubleshooting steps provided.

Because file corruption is the most common cause, running the aforementioned scans from a Windows recovery disc should generally resolve the problem.

In the worst-case scenario, you may need to have your hardware repaired or reinstall Windows.

Keep in mind to periodically backup vital data, keep your system updated, and take safety measures to avoid unexpected power outages. It is suggested that you get expert help if you experience persistent problems.
