  • Well, first of all ...

    If you want to use the Windows Boot Manager ... I think you have to install Win-7, then Win-8.

  • Actually, what I want to do is to use VHD boot into Windows 7 so that I can have a separate development environment.

    Tried booting from Windows 7 DVD and it does boots up but hang at the WIndows logo.

    If I need to install WIndows 7 first, that would means I have to rebuild my Alienware M17R4 with WIndows 7 which will wipe everything from my Alienware.
