Use Carbon Copy Cloner to make a bootable copy of your current OS X version on your second drive. 2. Boot from the second drive. (Hold down the option key whilst booting to select the boot drive.) 3. Open App Store and select Mountain Lion to install. As you have already purchased the software you will not be charged again. 4. Go and have a cup of coffee whilst the OS installs.
