So I just updated the EFI thing. I did the initial shutdown. The when I booted up I was greeted to a loud error-like tone before the grey screen and progress bar loaded. Then when I log back in and am browsing, OS X quit on me and produced this screen: I am using my HD out of my Late 08 MB without having reinstalled OS X from the MBP discs provided in the box. Does anyone think this is the reason for this problem? When I look in the System Profiler, all of the MBP hardware shows up. Same goes for Boot Camp and Vista.
