Yeah, I somehow fixed it by replacing my C:\windows\system32\config\system and another file also called system, they were 404kb and about 6 Megs with the one I had on my computer (computer one, with computer 2 being the one I'm trying to fix).
I tried booting it up after this and it didn't work(computer 2). However on the computer on which I'd gotten the files (computer 1) I had to re-activate windows (because I attached a hard drive on it and that made the accountants and M$ angry?) But, then I went into recovery console on computer 2 that and did nothing, changed directories a few times then got out and booted normally, the computer worked just fine.
How could this be?!
