Hi guys,

I installed windows 7 in F:/ long time ago. But now I want to try Windows 8 beta, which is amazing. So I want to delete Win 7, and formatted F:/. But every time when I boot the computer, a Windows boot manager will come up before entering the system. I do not know how to remove it completely.

Pls advise!

Thanks for any help!

Type msconfig inStartmenu, remove the useless menu in the guide options.
