If you are two facing problems related to Unmountable Boot Volume error, which is not allowing you to log in to Windows 10, then don’t worry, in this guide, we will tell you how you can fix this problem.

This Windows stop code error is indeed a headache. And since you cannot log into Windows, you cannot even troubleshoot it as you usually do.

But, this problem can be solved with the right approaches and methods. Before we start with the breakdown of how you can fix this problem, let’s take a look at what Unmountable Boot Volume actually is so that you get a better idea about this problem:

Unmountable Boot Volume:


The section in your computer that holds Windows is known as “Boot Volume.” This problem happens when the computer can not properly load Windows, leading to a death screen in blue. 

A “stop code” is the customized error message identifying the issue that Windows has run into. In such a situation, it’s the unmountable volume stop code for the boot.

Try Rebooting Your System And Check If It Happens Again:

Like other Blue Screen notifications, if you just see it once, the unmountable boot volume error isn’t really a problem.

Windows often run into a temporary glitch, in which you never have a problem again. 

When you see the blue screen with unmountable boot volume error when operating, restart your PC and try logging in again.

If the error hasn’t returned for some time you should be relaxed.

Create Windows 10 Installation Media:

As you are not able to log in to Windows as you usually do. So, using another machine, you will have to create a Windows installer on a USB drive or DVD.

This will allow you to access troubleshooting apps on Windows by booting from another system. 

Fortunately, now you can easily create Windows 10 Installation Media with the help of Windows 10 Media Creation Tool.

When the installation media is created, link it to your system and boot via DVD or USB. To do this you probably need to change the order of the boot on your Computer.

Try Using Windows Automatic Repair:

Try Using Windows Automatic Repair

Wait for a while until the Windows is loaded from your USB, then click Next. An Install Now screen will appear. 

But, since you are not considering reinstalling Windows, you will select the Repair Your Computer option. 

To get a list of Advanced Options, click Troubleshoot on the following page. Select  Startup Repair and pick the goal OS: Windows 10 (or the version you are using). 

Windows will run an automated fix from here, which we hope will take care of your problem.

Exit the installer once it’s done, and try booting your computer normally.

As The Last Resort Try SFC Scan:

As a last resort solution for Command Prompt, you can try another effective way. System File Check (SFC), it will find corrupted Windows File in your system and will help you eliminate them.

Still Not Getting The Result? Try Test Hardware And Reinstall!

Still Not Getting The Result

After trying all the above-mentioned options, the problem of unmountable boot volume is still not solved, then you must be facing some other serious problem.

But, don’t worry, you are still left with two options that can solve your issue:

The first problem you might have is a hardware problem. Systems’  storage file could have been corrupted, or does not have a proper connection.

If you are sure, open your computer and check to ensure a safe connection to the hard drive cable.

Malfunctioning RAMs can also cause this problem sometimes, so ensure the RAM sits properly. 

You should run some diagnostic study to confirm if a component is dying if you check the connections and everything looks fine.

Replacing this should fix your problem, but if you can’t swap the components yourself, you’ll need to talk to an experienced computer technician.

Your Windows installation may be corrupted after the hardware has been ruled out in a way that the above-mentioned method can not fix.

In such cases, reinstalling Windows is your only option. It’s a pain and it takes a lot of time, but if you already have a backup, it’s not as bad.
