dropped mac book pro
A teacher dropped her Macbook Pro 13 in late 2011. I was able to firewire in and verify disk, it checked out OK. Opened the machine, reseated the hard drive, RAM and battery. Made sure all connections were tight. i am able to CMD-R into recovery but choosing the Startup DIsk just brings me back to the grey screen and spinning wheel. Also reset PRAM and SMC. any help would be appreciated.
Mac Pro, Mac OS X (10.7.5)
