So I just replaced the hard drive in my early '08 MacBook Pro and I was looking to install Windows 7 on a boot camp partition. The only problem is, I did a clean install of Lion, which only allows you to install Windows 7. The copy of Windows 7 that I have is the $30 upgrade copy they offer to students. It's a 32-bit Professional key, and you need to have either XP or Vista on the computer in order to utilize it. I also know that Windows 7 distinguishes between upgrade and full-install keys, i.e. I cannot simply borrow a 32-bit Professional disc and use the key I have to activate the installation. However, I'm wondering about Anytime Upgrade. I'm not entirely sure of the exact process, but I'm wondering whether or not you can use a trial version of Windows Home and then use Anytime Upgrade with this student upgrade key in order to have a legitimate/"genuine" copy of Windows 7. Anyone have any particular advice on the matter or any ideas as to what I can do to utilize what I have at my fingertips instead of buying a new copy of Windows?
