Greetings! We are unfortunate to have both of the Mac Pro's listed as incompatible with Win 7 here: http://support.apple.com/kb/HT3986 We get all the way to the "Completing installation" phase of Win7 Installer "Step 2" and the installer hangs. Has anyone had any luck hacking their way into a solution for this? I can't believe our bad luck and we are desperate to get this working as we can't really afford new hardware and we have 16GB of ram investment to protect as well. Should this thread be in the Running Windows on a Mac Forum? If so, please move, but members there suggested to another user they post here since it is a Mac Pro issue....thanks again.
