I have a Dell dv6700 laptop that keeps bringing up the operating system not found error.Its running windows vista. While I was in Iraq our interpreters computer did it, he had a different machine but my buddy and i cant remember what we did to his so we can do it to mine. I think I have the recovery disk but it doesnt want to take any of my backups. This problem has been pissing me off for a while now any help will be aprreciated.
