I setup an image and then it asked to reboot. The computer never rebooted, it locked up before the windows booting screen. Now when I boot I get a seletion screen of where I want to boot from: A drive, Windows system, Linex... The only one that works is Windows system and the computer boots up fine after I select that one. I want the selection screen gone, how do I get rid of it? This is a Windows 7 machine BTW.
