Step 1 – Fixing Corrupted Boot Volume

First of all, this first step of this troubleshooting guide is for those who are getting this problem on their Windows Startup because if your Operating System’s Boot Volume got corrupted, then there is no way you can start your computer normally without fixing it.

If you are having this issue while working on windows then you can feel free to skip this whole step and move to the next one listed down below.

To fix the Corrupted Boot Volume of your computer, there are two different ways what you can try to make it fixed and the first one, using Startup Repair Utility Tool by taking the help of your Windows installer Setup Disc or USB, and in case when the problem isn’t get fixed by startup repair, then you’ll need to follow the instructions for fixing the Boot Volume manually by using the Command Prompt.

The First Method – This feature is very useful and effective Windows Repairing tool and the main work this feature do is to repair your Windows when something prevents your Windows from starting, or in a normal language, I can say it just restore the boot volume files when your Operating system is having some problem to boot itself.  You Can Click On This Link To See >> “Startup Repair – What It Is And How To Use It?”

Or otherwise, you can move to the next solution if you’re having this problem in the middle of your running Operating System.

Step 2 – Fixing Corrupted Windows Files

90% this issue starts just because of some corrupted files of your Windows OS. Mainly when that file starts to get in the process, you got this error appears on your computer’s screen and yes I know, it happens a lot while doing some important work on our computer.

So Let’s See the List of Solutions What Now You’ll Need to Follow In Order To Fix Your Computer:

  3. Windows Registry Got Corrupted – Registry is the main key for your whole windows working and performance, due to poor computer system maintenance, you may experience Registry issues and later on lead to various computers error, including this Unmountable Boot Volume error.

To fix the registry issue you’ll need to buy some best in class registry cleaner to repair and clean the bad values from the registry database. All the working Registry Cleaner are only available in the paid version but before spending your money, first, I want you to fix the registry issue by using your windows command prompt because most of the times this problem get fixed by just putting a single command in the CMD and then you don’t even have to buy anything.

Use SFC /SCANNOW To Repair Windows –  Sfc Scan is a great command run by CMD which can help you to repair your Windows by just typing a single command in the Windows Command Prompt. Now you’ll just have to type the command on CMD and sit back until the scan completes and it will repair most of your Windows files including the registry database.

  • Open CMD, as an administrator.
  • Then type the command “Sfc /Scannow” and hit enter. Make sure you don’t close this CMD window until the verification gets 100% completed.
  • Restart your computer and test it, if the blue screen was gone, then that’s good, if don’t, then I think now you should need to buy a Registry Cleaner for your OS.

If you don’t have any registry tuner or cleaner in your computer, then install a best in class cleaner in your PC to get the perfect performance and an error free system’s lifespan.

According to my experience here are two top best-rated software’s which you can use to make thing back to normal in your computer system:

Step 3 – Error Fixing By Changing A Bios Setting

Mainly, this step is only for those users who have this problem while installing Windows on their computer or laptop. If you do having this kind of condition on your side too, then this little trick will definitely help you out to solve this Unmountable_Boot_Volume problem from your PC.

  • I can’t say 100% but almost 90% users did found this trick useful and I hope this will also work for you too. And to do that, first, you’ll need to hit the Del or F2 key on the keyboard again and again, right after when you start your computer system. If your computer is Powered ON right now then you’ll need to Turn it OFF and then again Turn it ON to do the Del or F2 key pressing procedure because you can only do that when your computer’s first Black Wallpaper Type Screen appears on the startup.
  • When you successfully get into the BIOS Menu, then now you’ll have to search for the setting called “SATA mode” or “SATA configuration”.
  • After when you find the setting, now you’ll need to change it to “AHCI” Mode.
  • At last, you’ll just have to save the settings and restart your computer and that’s it. After that, try to install your Windows again in your computer and I hope this time you positively install the operating system without getting any BSOD errors.

If the setting is already in IDE mode then you can also try another mode to fix this error, or otherwise just move on to next step.

Step 4 – Fixing Fault By Troubleshooting Hardware

If any single solution procedure from above doesn’t work for you, even re-installing windows, then it’s 100% possible that it is a hardware related fault and just like I said, this Unmountable Boot Volume error is related to the storage device and now you’ll have to troubleshoot all of the storage device connected to your computer.

Sometimes it’s also quite possible that your computer’s BIOS are corrupted too and to troubleshoot all those hardware what I’m talking about, there are 4 possible things what you can still try to identify the current hardware failure, and what you’ll need to repair. Those are –

  1. Try to full format your Primary Storage Devices like your HDD or SSD and then install the perfect Operating System on your computer.
  2. Try to replace your HDD’s or SSD’s SATA cable, which is normally connected to the motherboard from your Storage Device. >>Click Here To Check Out The Price Of New SATA Cable @Amazon
  3. Use some another HDD or SSD in your computer.
  4. At last, update your Computer’s or Laptop’s BIOS.
