Can't get out of OS X Utilities Screen
I have a MacBook Pro, non-Retina 15inch that I purchased about 2 years brand new from the US Navy base. As from what I remember it didn't come with any backup CDs or what have you. All was fine until I updated to Maverick (Mountain Lion was what originally supplied), and things went down hill from there. First all my apple products and printer wouldn't sync correctl, then there was some sort of big issue with my apple ID that I was forced to change my ID since and as result things been a bit confusing since. But that's not why I'm writing here today.
Earlier today I used my MBP for the first time in a couple months. After start up my Safari was opened and so I closed it, then I was informed that iTunes needed to be updated, at first it said it couldn't be updated but it did. Then I deleted my trash bin - have a feeling this where I did wrong, for I didn't really look over what I was deleting. After that my entire MBP froze. Nothing was responsive. So I did an forced reboot (holding the power button down, etc). Upon start up, first there's a white screen with a forbidden sign, then the gray screen with the apple logo, and finally the Disc Utility screen. Unfortunately, I never did the Time Machine thing - so that's a no go. I can't do a Reinstall OS X - shows 2 disks, EFI (not formatted as Mac OS Extended Journaled) and Recovery HD (shows as "this disk is locked"). I did try Disk Utility to repair, for what's listed as "Apple HDD HTS541075A9E662 Media" everything appears to be fine by means of verify disk and repair disk. Another disk labeled, "Macintosh HD" first I have to verify and then during repair disk it stats it can't be repaired. In the details window it looks to be missing directories.
So as you can see I'm stuck and screwed. Have no clue what else I can do.....
Oh, and yeah - I tried to start in Safe Mode by means of holding the Shift down during boot up, that didn't work either.
If anyone understands what's happening here, much obliged. Otherwise being I cannot remember if my MPB is under warranty or not, anyone have about round about figure what it'd cost if I need to bring it in the Genius Bar?
