So, I made a big boo boo and put Windows 8 in a boot camp. Worked fine for a while and played some Steam games. Then today I booted into Windows 8 from OS X, but ended up in a Repair loop. I've tried all of their recovery options and all failed. I've no idea if there are any command prompts that would help. Holding option when rebooting doesn't bring up the startup drive option. Can't reset pram, no recovery keystrokes work. Is there anything I can do to get back to OS X?
