Windows 7: HELP Windows 7 Breaks BIOS after Installation

In that case it could be boot code on the HDD blocking boot.

What happens if you attach the HD to another PC? Will the PC boot it's own OS with the same HD plugged in?

Can you access the problem HD to rescue your files and run a HD Surface and File Check with PW CD?

If so try booting again in the problem PC and if it won't boot anything including PW CD, put it back in other PC to wipe the HDD with Diskpart Clean Command
