Ok folks, here is the thing. A laptop I'm working on got infected with a bad virus and was only able to boot into safe mode. Pretty soon the infection got so bad that it wouldnt even do that. Whenever I try to boot (in safe mode or normal) it loads for a minute or so and then the BSOD pops up saying UNMOUNTABLE BOOT DRIVE. I have tried using an external hdd to see if I could make it boot off of that (like a live cd) Nothing, all I get is a black screen with a blinking line in the upper left hand corner. I have checked on a couple of different systems to make sure that I created the boot disk properly. I did. I made sure that the laptop could boot from usb devices and I even made sure that it booted to the usb device. Now I'm stuck.

So here is my question:
1) Is there any way to back up the data on the laptop if I cant boot and using a live cd dosent work?
2) Any other suggestions on stuff I could try to fix this?

I ran into this error for one of my clients yesterday, and you should be able to repair the drive by running CHKDSK. Do you have your original Windows CD? If you boot to it first, then load the recovery console, you can run CHKDSK /R at the command line and it should repair your issue.

Also, the percentage may drop back down to 50% occasionally as it runs, I researched this and it is based on the tests that are running in the background, and the process should take about 45 minutes to an hour. DO NOT interrupt it though, it will finish eventually!

FWIW: Unmountable Boot Volume errors...are pretty old-hat and have no necessary connection with malware.

Your diagnosis may be wrong, you may just have a bard hard drive.
