Reboot and select proper boot device error

Last night my computer froze and gave me a BSOD, and when I tried to simply restart it, it would get to the windows splash screen and BSOD again. Then after trying a few things to fix it, its giving me the 'Reboot and select proper boot device etc'. Ive checked command prompt and it is showing my HDD as the 100 meg system partition that W7 makes when installing, but I cannot access the rest of the drive.

Took the HDD out and to a mates place so I could get anything i needed off it before I just wiped the drive completely, and his computer did the same thing after a few minutes.

From that I assume it was a virus of some sort, and for me I can lose what I have on the HDD without caring too much, however he has things not backed up on his HDD that he really needs to recover.

Has anyone had this problem and been able to recover the data somehow?

A simialr problem happened to me and i fixed it by putting in the windows 7 disc and do a repair twice, doiing it twice fixed it dont no y and i lost no data at all
