Hey all, I have been defeated. after spending the last few days attempting to find a way to get windows 8 on my rMBP, error after error has finally lead me to ask you geniuses what to do. I have an x86 Windows 8 iso just begging to be used. And a correctly formatted USB drive. I have the iso and drivers burned to discs, but apparently windows won't boot from external disc drives.... Every time I try to restore the iso onto the usb, i get either an "invalid argument" error or "error 254." Driving me nuts. I know there must be more information to be had in order to diagnose my problem, but i suppose i don't know what to tell you. If you have a fix, PLEASE tell me, or ask for more info so i can help you help me. Thanks!
