I am using a i5 3750K, a Z77 Extreme 4 mobo, and a MSI GTX 560 Twin Frozr II. After installation using the boot flag "PCIRootUID=0" I can't reenter the OS. When I try enter ML I hang on the Apple splash screen with the spinning wheel underneath. Help, please! I have been troubleshooting this problem for two days and I am getting a major headache!
