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

One of the most dreaded things to see on Microsoft Windows system is the Blue Screen of Death. In this instance, I had a computer show the Blue Screen of Death upon booting claiming:

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

This error can either be caused by a problem with an IDE cable or the BIOS in which case you just replace the cable or reload the fail-safe default settings in the BIOS. However, most of the time this error is caused by some sort of problem with the volume.

To fix this problem you will need:

  • A copy of the Windows Installation Disc
  • About 1.5hrs of time

Fixing the problem:

  1. Boot up your computer to the Windows Installation Disc (You may need to press a button like F12 to see the boot menu)
  2. When the Windows Welcome Screen loads press the R key on your keyboard
  3. Once you get to the command prompt type chkdsk /r then press Enter
  4. When the check disk is complete you will be returned to the command prompt
  5. Type fixboot and press Enter
  6. When the fixboot is complete, type Exit and press Enter
  7. Your computer should reboot and your problem should be gone.
