Mountain Lion booting up to utility
So today I restarted my MacBook Pro and by surprise I ended up in Utilities.
I repaired the disk, started up with my main disk, erased RAM... doesnt work
Safe mode, doesnt work.
Booting up by holding down Option key, it gaves me 2 choices, my main disk and recovery. By chosing the main disk it takes me back to Utility.
All help is appreciated. Thank you in advance.
MacBook Pro (15-inch, Mid 2012), Mac OS X (10.7.4), 2.6 GHz Intel Core i7//8 GB
