How to fix unmountable boot volume error?

I got an unmountable boot volume error and my system won’t start properly. What does this mean and how can I fix it? Looking for easy steps to resolve it.

That error usually means Windows can’t read your system drive properly, often due to file system corruption. The quickest fix is to boot into Advanced Startup (restart and press F8/Shift+Restart), open Command Prompt, and run chkdsk C: /f /r—this scans and repairs disk errors. If that doesn’t work, try bootrec /fixmbr and bootrec /fixboot. I’ve seen chkdsk fix it most of the time, but if it keeps coming back, your hard drive might be failing, so backing up data early is a good idea.

Unmountable Boot Volume error is typically a result of corrupted system files or disk problems. Reboot your PC and boot into recovery mode, after which you run CHKDSK /r and SFC /scannow via Command Prompt. You can also try Startup Repair. In case the issue continues to exist, verify your hard drive cables or think about substituting the disk.
