No booting, No reinstall.
My MacBookPro is not booting. After a start, loading, a grey screen appears, and the fan speeds up. Have tried Cmd-R-Shift-Alt combination during upstart, and a message tells about reinstalling via internet. But no results, grey screen and a sign: Apple.com/support bullet501 0f. Can I rescue my mac?
MacBook Pro 15″, OS X 10.10
