Unknown Hard Error - Startup Repair is checking your system..

[rgsilent]

I got a Blue Screen saying nothing except Unknown Hard Error on windows 7. So I restarted the computer and when I booted Seven, windows first popped up with a message saying windows is loading files and then Startup Repair popped up saying

Startup repair is checking your system for problems.

It completed once and restarted but same thing happened again. And now startup repair keeps going on and on.

Can someone help me out?

I'm through the same comp using windows xp on a dual boot so I don't think hardware is acting up.

This is the thread on BSODs I kept having on the seven:

Bump...reinstalled both Operating Systems after I started getting ntoskrnl.exe not found. Ended up losing 260GB of data. Ah, well..
