I just reinstalled OSX on my MBP last night and today it wont let me boot into it. When the computer is starting up it gets to a blue screen and nothing happens it just stays like that. I thought at first it was a permissions problem so i Repaired Disk Permissions using my OSX 10.6 disk and still no luck. Here is a pic of what the blue screen looks like: Any help is appreciated. I want to be able to fix this without have to reinstall the OS all over again. Also my Windows 7 Bootcamp partition works fine.
