I have the following CD's:
- Windows Vista Home Premium (Upgrade)
- Windows Vista Ultimate (Full)
- Windows 7 Professional (Upgrade)
I would like to install Windows 7 on a mac with boot camp. It seems that Apple doesn't support installations via upgrade discs.
From what I understand, this means that I can't simply begin the installation using the Windows 7 CD, since it is an upgrade version. What I didn't understand, though, is if I can upgrade the OS once it is installed. For example, if I install the full version of Windows Vista Ultimate, could I then upgrade it to Windows 7? Or is my only option to purchase a full edition of Windows 7?
