This disk cannot be used to startup your computer

Downloaded Mountain Lion from the App store. The installer shows "This disk cannot be used to startup your computer". I tried to adjust the partition size as suggested and still wont install. Checked permissions, Checked partition map scheme = GUID, Verified Disk, Smart Status = verofoed...etc.


Anybody got any ideas.User uploaded fileUser uploaded fileUser uploaded file
