Sorry to be a bother but I really am confused on how to get the Laptop to boot from the USB key, it's not seeing it.
Use Disk Utility to create a DMG of your Mac OS X install disk (on a real Mac or other Hackintosh). Then partition a flash drive (>=8GB) with GPT and a single partition. Use the "restore" feature to restore the DMG to the partition on the flash drive. Then install Chameleon (either manually or just with one of the packages, such as #####). Then you should be able to copy the "Extra" folder, and the "boot" file. (Also a kernel if you need that.)
