I have the full version of XP SP2, and an Upgrade version of Vista Ultimate (32 & 64-bit).
I'd ultimately like to get Vista Ultimate 64 installed on my Mac Pro. What are my options here?
On my former Windows machine (now a Linux host), I simply installed Vista Ultimate Upgrade, then re-installed over the previous copy to comply with Microsoft's rules on upgrading.
Can I do the same in Bootcamp?
I suppose my only other option would be to install XP, then upgrade to Vista Ultimate, though that would mean I could only upgrade to the 32-bit version which would be a problem because I need it to recognize the full 10GB of Ram I have installed.
