And it worked. Installed 8 from legit DVD, then updated to 8.1. Then did the HFS, NTFS and time sync fixes and now I have a true dual boot system. For all it's unwieldiness with a nonTouch screen 8.1 is looking much nicer than Mavericks, at least on my dual monitors (the second one is a 2550x1600 or something like that, which the imac was not driving properly).
