I installed the new update onto my external drive. I have migrated my previous user accout settings, etc to the external drive. No I need to reformat my internal drive then reinstall the external drive to the internal drive. How do I do this??

MacBook Pro, OS X Mountain Lion (10.8)

    Use the Disk Utility to erase the drive, and then a product such as Carbon Copy Cloner or SuperDuper to clone the system.

    Not without installing an OS on the internal. If you made a Time Machine backup, you can restore it using the utilities on a Mac OS X install DVD or recovery partition.

    You need to install an OS on the internal if you want to use the Migration Assistant to move data to it; it can only move data to the system being used to start up the computer.

    To copy yor external drive contents to your internal drive, making it a bootable drive, install Carbon Copy Cloner to your external drive. See http://www.bombich.com/. Use CCC to reproduce all of your external drive to your internal drive. Then, you will be able to boot your internal drive.
