Well I too what recommend something with the disk..
I guess you could unconnect the Drives from the IDE cable, and then start your computer and let it load windows. Shut down correctly, then reconnect the cables.
When the computer restarts, try hitting the Del key, or if you know what key enters you to your bios, and see if it recognizes them.
Not very practicle, but maybe youll get lucky :/ - something similar happened to my friend.
