So all of the sudden my mbp will not boot past the spinning wheel/apple screen. I have not let it try for longer than 15 minutes but I don't see the point. I tried to boot in safe mode(hold down shift) but the bar only went to about 1/3 and stopped/disappeared...so I don't know what to do. This shouldn't be happening after a couple months of light use. Any ideas would be greatly appreciated. Before anyone asks, yes I did search for my answer. This is the closest/most recent thread with a related problem(http://forums.macrumors.com/showthread.php?t=860632), however it was never answered.... Just for extra info: I am able to boot into windows 7 via boot camp. Cannot boot from cd or go into safe mode.
