UNMOUNTABLE_BOOT_VOLUME

Introduction :
The computer at home recently ran into BSOD with the error message “UNMOUNTABLE_BOOT_VOLUME“. Not quite sure what was the root cause. The machine boots till the bootup screen halfway and the BSOD appears with the error message :

STOP 0×000000ED (0xaaaaaaaa,0xbbbbbbbb,0xcccccccc,0xdddddddd) UNMOUNTABLE_BOOT_VOLUME

After some digging, found an KB article by Microsoft that suggested some remedy instructions. I took the second option because I was pretty sure the physical cabling was not the culprit.

Enviroment :
Microsoft Windows XP service pack 2

Installation / Usage :
Method 2: Damaged File System

If this is the case, restart the computer to the Recovery Console, and then use the chkdsk /r command to repair the volume. After you repair the volume, check your hardware to isolate the cause of the file system damage.

To do this, follow these steps:

1. Start your computer by using the Windows startup disks, or with the Windows installation disk if your computer can start from the CD drive.
2. When the Welcome to Setup screen appears, press R to select the repair option.
3. If you have a dual-boot or multiple-boot computer, select the Windows installation that you want to access from the Recovery Console.
4. Type the administrator password when you are prompted to do this.

Note If no administrator password exists, press ENTER.
5.??? At the command prompt, on the drive where Windows is installed, type chkdsk /r, and then press ENTER.
6.??? At the command prompt, type exit, and then press ENTER to restart your computer.

If this procedure does not work, repeat it and use the fixboot command in step 5 instead of the chkdsk /r command.

After the CHKDSK (short for Checkdisk) program runs the recovery, it will show some statistics. If everything ran properly then just type exit and the computer will reboot and boot into Windows. Remember to remove the startup disk/windows installation disk from the drive.
