Yosemite not installing after Restart
Hi,
I have Macbook Pro running on 10.6.8. I downloaded yosemite OS installable from app store. Installation goes fine. But after restart, it does not continue with further installation of yosemite and goes back to 10.6.8. There is no error message and system runs fine on 10.6.8. Any help on this will be highly appreciatd. Thank you.
MacBook Pro, Mac OS X (10.6.8)
