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.

Customer has a laptop that no longer starts.

Before I saw it, I thought it would be another corrupt registry problem.

when I got to the laptop, I could see it was partly starting xp, and then would blue screen of death, with the error: “unmountable_boot_volume”.

So I decide to boot from bartPE, but I found I couldn’t do a fixboot command. Customer didn’t have the original XP installation CD, so I had to take it back to the office.

I then removed the HDD, connected it to the office PC, and backed up all the important data.

While that was happening, I did some research, and I found that a chkdsk /f , followed by a fixboot should fix the problem.

So I do the chkdsk /f e: (it took a while), but the fixboot e: command returned: fixboot is not recognized as an internal or external command … etc

OK, it looks like I’ll need to boot to the recovery console to complete this.

So I plug the HDD back into the laptop, start it (expecting to see the BSOD), and the PC boots normally 🙂

OK looks like I don’t need to do the fixboot after all. Cool!
