Unmountable boot device

IBM Thinkpad

Specs: Windows XP, 256
My laptop keeps restarting itself. It won't even get into Windows before I get a blue screen saying UNMOUNTABLE_BOOT_DEVICE. Plus some other stuff. After this it starts over, and is on an infinite loop. I've tried starting up in the "Last Previous Configuration that Worked" and in Safe Mode but they both do the same thing. You can see a video of the situation in the first link. You can see a picture of that blue screen in the second link.. Yes the quality isn't great but if you squint you can read it and if you set the video on loop you get the idea of whats happening.... Any ideas?

My guess is a hard drive problem. If you have a hard drive diagnostic run it. Otherwise download one from the IBM/Lenovo site.

A memory problem is another posibility.

Memory test

There is a version to create a bootable floppy diskette and/or an ISO for creating a CD.
Run it overnight and any failures are unacceptable.

Bootup to your Windows CD or a boot CD. Pick the Repair option from the initial Windows install menu, (before it asks you to confirm you read the license). Pick the Command prompt option. Pick 1 (C partition), then run chkdsk /r or /f. Let that run, you may be fine but you should backup your data. Your drive may be going bad.

Excellent advice from dondreak. The chkdsk /r option is a very good test of the drive, but be aware that it can take hours on a large drive.

All your help is appreciated, what I finally ended up doing was almost exactly what you said. I ran chkdsk /p and then fixboot from the recovery console. I used the instructions found here:

That seemed to do it. Computer is back up and running!
Thanks.
