Gregrocker, the computer in question is one that a friend tried to uninstall Ubuntu on, found he was unable to complete the process and just abandoned it a few weeks ago. There's no need to be insulting. Even though I stumbled a few times I was successful in reinstalling Windows 7 without your help.
