    I have two internal disks at my mac mini, so this is an option. The process seems simpler than create bootable usb drive. My only question is, once I get Mountain Lion installed on my second disk (non-start up), I wouldn't have any conflicts between the two system? I don't intend to keep both at my computer. My idea is to format the old start-up disk as soon as I get Mountain Lion running on the other one.

    Why not use CarbonCopyCloner or SuperDuper to "clone the OS over" ??

    Since you're going to re-initialize the first drive, I would do this:
    1. Copy anything I wanted to keep from the second drive to the first
    2. Use disk utility to re-intialize the second drive
    3. Use CCC or SD to clone the first drive (which now has "everything" on it) to the second
    4. Boot from the second drive, then use disk utility reinitialize the _first_ drive.

    From there, you can do whatever you need with the "first" drive...
