STOP 0x000000ED UNMOUNTABLE_BOOT_VOLUME error message in Windows XP

One of the most popular BSOD or Blue Screen of Death is the unmountable boot volume message with stop code 0x000000ED. This is usually cost by a corrupted boot.ini or possible bad hard drive. To resolve this you will need the OS CD of Windows XP. 


How to Fix Unmoutable Boot Volume using the Recovery Console
1. Change the boot setting of computer. Let it boot from CD first.
(BIOS can be access most of the time by pressing F2 or Del when you first powered on your computer. Put CD ROM as the first on the order of your boot sequence).


2. Put Windows XP CD to your CD drive and when you see the message "Press any key to boot from CD...." Hit any key right away so that it will load the OS CD. You only have like 3-5 seconds to do it. If it did not read the CD then reboot your computer and try it again.

3. Once the cd is finished loading you will see this screen. Press 'R' to enter Recovery Console.


4. Below is the screen of Recovery Console.


Choose where you have windows installed. In this case we only have one option. Type '1' and press enter then you will be asked to enter administrator password. Usually the password is the administrator account that you have on your computer or you can just leave it blank if you don't have password. Hit enter once you've enter your password and it will go back to C:\WINDOWS>.

5. At the prompt type 'chkdsk /r' and hit enter. It will run for a while depending on the size of your harddrive. Once its done type 'exit' and let your PC do a normal reboot and see if it would still get that error.

6. If you still have the same problem you can try using 'fixboot' in the recovery console. (NOTE: Don't do fixboot if you have PC Restore or OS Recovery on your harddrive because it may no longer load if you do a fixboot)

If these two didn't resolve the issue you can also try to repair your computer using windows XP CD or just do a reinstall of your OS. One possibility also is you have a bad hard drive.
