    I got the same error if I launched SL setup from within OS X, but it worked fine when I held Option key during startup (same as bootcamp) and selected to boot from my ext. drive

    Try System Preferences -> Startup Disk and selecting your ext. drive.

    does the partition have a guid partition table, so it's bootable?

    Click on the drive in Disk Util, does it say: Partition Map Scheme: GUID Partition Table? It probably won't work otherwise.

    no it doesnt say that,

    but i did the same procedure with leopard and installed it no problem...

    how do i get around in making the scheme if that is the problem?
