I am running Windows 8 Pro Package with very few glitches.Mainly reboots to switch OS's,all understandable seeing Win 8 really isn't supported on Boot Camp ,,,yet. I used the Win 7 drivers pac, and standard Boot Camp software installation.Have Fun,,I'm using my printers, ext. HD's, Apple TV.
Granted, I had to "PLAY" with it for a while, but playing is fun,,,right? ;-)
If anuone else is trying tis, drop me a note ,or reply to post.
OH, and I've done this on an iMac with only a 256GB SSD,,no other internal storage.
