Reader Question:
“Hi Wally, I’m looking for an answer to this question. I upgraded my computer from Windows 7 professional to Windows 10 Professional. Now, I’m seeing blue screen errors saying Unmountable Boot Volume. I can’t find a solution to this problem.“- Christine E., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Microsoft’s activation statistics show that Windows 10 was activated 75 Million times in the first month of its release. But as with any software, there are problems that might appear in some cases. Here we will tell you how to solve the unmountable boot volume issue.

Problem

The unmountable boot volume error appears and Windows 10 Professional fails to boot normally.

Cause

The unmountable boot volume error can be caused by:

A faulty hard drive.
A corrupt boot partition.
Corrupt Windows files.

Solution

Here are some ways to solve the unmountable boot volume error:

Boot Your Computer With The Windows 10 DVD/USB

You can do this easily if you already have a bootable Windows 10 DVD or USB on hand. If you don’t, then you can download one using the Media Creation Tool.

Make sure to download the correct version of Windows 10. You will need to know which Windows 10 version to download. You can find that information on this page. If you’re using Windows 10 Pro then select Windows 10 Professional.

Automatic Startup repair

Boot your computer using the Windows 10 DVD or USB
You should see the Windows Setup screen. Click Repair your computer as shown in the image below.
Click the Troubleshoot tile
Click the Advanced Options tile
Click Automatic Repair and wait for the process to complete.

Use The SFC /SCANNOW Command

The SFC command can be used to replace corrupt and missing system files. Here’s how to use it:

In the Command Prompt window, type sfc /scannow > Press Enter
You can also try using the chkdsk /r command in addition to the sfc /scannow command.

If all else fails then try using the Windows Recovery options to reinstall Windows.
