Long story short. Something bombed out with my computer while I was using it yesterday and I'm now no longer able to start it. I've tried using Startup Repair 3 times with no joy. So I'm going through the process of repairing. I'm at the command 'del C:\boot\bcd, and I'm getting the message "The request could not be performed because of an I/O device error". Please help! I'm desperate to get this computer up and running again, I have multiple important files on it.
