I downloaded the mountain lion install app and now i can't install it I get the "This disk cannot be used to startup your computer" error when I try and install. If i back out to the main install page and try it again then i get this error "OSX cannot be installed on Macintosh HD". I have read similar posts and done appropriate responses such as verifying and reparing the HD. I have a Time Capsule that I backup to and I've tried disconnecting from it and ensured its not backing up during my attempts to install. Nothing seems to work. HELP!!!!




Computer Stats:

Early 2009 13" Macbook Pro

Model identifier: macbookpro 5,5

ram: 8GB

HD space available: 60GB

Processor: Duo core 2.53


Nothing out of the ordinary. I don't have any crazy setups, pretty much straight out of the box.
