Well, I just can't seem to get past the boot0 error screen. I'll have to put my nvidia card back in so I can address the issues. That's a PITA cause I crammed a Sapphire R9 270x Vapor-x into my Silverstone sg05 case. I had to take out everything but the mobo to squeeze it in.
I'll try moving the boot stuff to the EFI partition. I tried doing it from a mac Book by putting the mountain lion boot drive in a USB enclosure and using 1s2 for to designated drive but couldn't get it to work. Why wouldn't that work? Is it because I was on a MacBook that won't run Mountain Lion?
update:
Finally got the EFI fix working. So Happy. happy, happy, happy. Problem now is none of my color profiles work. Safari makes the whole system drag to a c r a w l. FireFox works fine though. Something's very wrong. But I'm encouraged that I got it to work at all. System profiler shows:
