Hey, I am running Lion on a Macbook Air 2010 model and i recently bought Mountain Lion through the MAC App Store. ive had problems installing it as i cant install it onto my Macintosh HD (startup Disk). Ive opened the ML installer and its rebooted my mac into the installer Menu, but when it goes to install, it stops and says You Cannot Install OS X on This Disk. OS X cannot start up from this disk." i want to be able to install ML overwriting Lion on my MacintoshHD (startup drive), are there any solutions that can fix this problem?

MacBook Air (13-inch Late 2010), Mac OS X (10.7.4)
