MacBook Pro w/ 10.7.5 won't boot
I shut down the Mac last night and all was well. This morning I started it up and first got a weird DOS looking screen that instructed me to restart. I did and got a folder with the flashing ?. I restarted with Option and am running disk utility. Lots of errors. Things seem to go well until the end of Disk Repair when there is a list of about 5 missing directory records and it says it's searching for them in "lost and found." It searches for 10+ minutes then I get the colored wheel. This is my third try and no luck.
I am trying to repair my hard drive but notice a Mac OSX Base System icon in Disk Utility. What is that and should I use it instead?
Sadly, no Time Machine back-up and when I tried recovering Lion it asks for a sign-on and password for the App Store that I don't have. It says I should create one, but there's no icon to do it.
I'm stuck! Help!
