Macbook pro boots to 'mac os x utilities' and disk utility can't repair the disk
Hi
My macbook pro froze a few hours ago so I powered off with the button. When I rebooted it came straight to the mac os x utilities screen. When I held option the screen remained grey. When I tried to repair disk it said it could not repair.
I do have a back up but I'm not great on computers and I'm very scared that I'm gonna lose photos etc.
Shall I just choose the 'restore from time machine backup' option? Or is there something else I should do?
Any help would be appreciated ASAP
Thanks in advance.
MacBook Pro, Mac OS X (10.7.5)
