I will be receiving a new Mac soon and would like to install Windows 8.1 on it via bootcamp. I see in the Microsoft Online Store there is a student download edition of 8.1 for $69.99 that says it is a full edition. Will that work? Also, I still have an official unopened Windows 8.0 upgrade retail disk that I haven't used yet. Can you still use that to do a full install? I see some old posts that say you can but I was wondering if it was still valid. Thanks.
