Unmountable Boot Volume BSOD Fix

If you turn on your PC and come across a BSoD stating UNMOUNTABLE_BOOT_VOLUME, don't panic! or attempt to reformat your computer. This is very common issue when running windows OS, and not so very hard to fix. The most common cause of this problem (base on my experience) is improper shutdown .

To resolve this issue, you need an original or untouched copy of windows XP, and  configure the computer to boot from the CD-ROM or DVD-ROM drive and follow this steps.

1. Insert the Windows XP bootable CD into the computer.
2. When prompted to press any key to boot from the CD, press any key.

3. Once you see a welcome screen, press R key on your keyboard. This will bring you into recovery mode with a DOS prompt.

4. Now type chkdsk /p and press Enter. This will launch a utility that will scanned for File System errors.
5. After the process is done, type FIXBOOT and press Enter and hit Y to choose Yes
6. Remove the Windows CD
5. At the command prompt Type EXIT and press the Enter key to reboot your computer.

And your system should now boot normally. This worked for me in most cases.
