So I have a friend who needs to run Windows on her Mac, via Bootcamp. She's a student, so she qualifies for that nice Win7 Professional $65 "ultimate steal." I'm guessing that simply buying the upgrade version and doing a fresh install via Bootcamp will not work, correct? If that's the case, I believe she has some version of Vista DVD from a Sony laptop she had prior. Will physically having that disc help the install cause? Will she need to install Vista first, and then install the Win7 Upgrade? Basically I'm looking to make this as easy and painless as possible for her. Any help is greatly appreciated!
