Thank you for posting this "How to". My husband closed my son's laptop while he had a game running. That corrupted the operating system so badly that it would not restart at all, not even autofix. I googled this site and was able to try several steps listed here, all of which failed unfortunately, until I got to the "create a recovery disc". I created it on my own laptop and was able to get my son's computer up and running again. This saved me (ahem, rather, my husband) a few hundred dollars at the repair shop!! Thanks again.
