I just upgraded my 13 inch Macbook Pro Early 2011 harddive from 320 to 750GB, installed the OS again, everything went fine. But then, I updated to mountain lion from snowleopard , installed the application install disc but nothing shows up on the screen ( I hear it spin for a while, then it ejects). I think it's because I tried to installed the application install disc after updating to mountain lion. How do I fix this?
