I use Parallels 9 on a MacBook Pro running OS X (10.8.5) to run XP Pro. Is the easiest most foolproof way to go to Windows 7 simply to eliminate the current virtual machine (Article ID 5029) and then install Win 7 in a new VM (Article ID 4729) from my new Win 7 DVD with product key code? Then I would install the few pieces of software I need to use in Windows from their original installation discs. Anyone have experience with this method and know any pitfalls?
