If you bought a new machine from Apple you have OS X 10.8 already installed – but no back up disk! and since you haven’t bought the OSX Lion 10.8 App from the App store you can’t re-download it – so thats why you have the recovery drive as a partition in your main hard drive, to boot from it you need to restart the machine and when it starts to boot hold down “command” + “r” keys. On every OS X 10.8 Mountain Lion there is a hidden partition to enable a method for Mountain Lion OS to be reinstalled on the machine, it is known as the Recovery Partition or drive and is 650mb in size.
