I installed 10.8.3 as well as rMBP SMC update yesterday. Afterwards I was using Windows 8 via BootCamp and put the mac to sleep. This morning it went straight for boot into recovery partition. I choose to boot in Windows 8 (which I'm using now), but I cant boot into Mountain Lion! When I choose the ML boot disk, it loads recovery partition. After trying "verbose boot" I was an error like 'unable to load mach_kernal'. I repaired disk and permissions.. no luck! I need this for work!
