stop 0X000000ED unmountable_boot_volume

PC wouldn’t start. It gave a blue screen of death (BSOD) with the following error:

STOP 0x000000ED unmountable_boot_volume

I thought: this is not looking good.

I booted from a bartPE CD, but using windows explorer, it would just wait for 2 minutes before timing out

Using a command prompt and entering: “dir C:” returned nothing (no error, but no contents either)… very unusual.

I was starting to think the hard drive was totally corrupt.

Next, I tried chkdsk C: /F

It found and fixed a few errors… and after that, C: was visible again… And the PC booted relatively normally.

After that, I had some time to tune the PC… and it needed it, as it was very slow to start. Besides the usual need for a defragment, deleting temp files, and rubbish startup programs, the customer also had multiple antivirus and spyware applications, as well as some minor infections.

Once I was finished, the PC was running at a speed I was happy with.

    Note: I was called back a few weeks later for the same reason. Looks like the hard drive is about to fail (although SMART didn’t report any problem!)

    I have the same error message with an added problem. The startup continues to time out even if I try and start in SAFE Mode. I can’t seem to get to a prompt screen. I have tried all options on F8 and only get to the error message screen using F10 and then selecting no to running the recovery; or hitting the ESC key somewhere along the way. I’m not sure how to get to a point where I can do a chdsk or anything else. Any suggestions?

    Use another PC to create either a bootable Bart PE CD, or a bootable UBCD4Win CD

    Thanks for the reply. Is there a procedure to create the cd’s described, I’m not familiar with how to do this. Also, if I create from a computer running XP Professional will it work for XP Home which is on the computer having issues?

    I can’t explain the procedure here… read the respective websites, and read the documentation.

    If you still can’t understand how to do it, then you need to call a computer professional.

    to run a chkdsk, it doesn’t matter if you make the CD from XP home or XP pro.
