Would it be better to backup my system on an external hard drive with SuperDuper, boot from that drive, repartition my external, then copy the system files to the newly created system partition? Or to backup, boot from install dvd, repartition, reinstall OSX, then use the migration assistant to copy my files and settings over? I don't even know if the first one is possible. If there are any other better options too, please let me know. Thanks.
