Step 1: Head on over to the Lion DiskMaker site and download the most recent version of the utility (currently version 2.0rc2). Also, download OS X Mountain Lion from Mac App Store.
Step 2: Open up the compressed file from the download location and run the executable file contained within. This will invoke an instance of the Lion DiskMaker utility.

Step 3: When the program window loads, it will provide you with a small amount of information as well as three buttons containing user options. Select the far right button which is labeled ‘Mountain Lion (10.8)’.
Note: In case the utility is unable to find your Mountain Lion image. Go to the Applications folder and find the copy of Mountain Lion you just downloaded.
  • Right click on the downloaded file and select “Show Package Contents”.
  • Go to “Contents” and jump inside the “SharedSupport” folder and you’ll find a file titled “InstallESD.dmg”.
Step 4: Lion DiskMaker will now present you with option to either “Burn a DVD”, or “Create a boot disk” using Flash drive or SD Card.
Step 5: Sit back and enjoy the magic that comes from running a fully automated tool that has the intelligence to make itself look like black magic.
