    The loaner computer I am using is running Tiger. My clone of my computer thats in service is Leopard, every time I hold option and try to boot from the external clone it tells me this computer needs to be restarted....can I just not boot from an external drive? whats going on?

    Is it still cmd-opt-shift-delete to choose to boot from the external?
    BTW, some Macs only boot from firewire (ppc). An Intel Mac should boot from firewire or usb.

    IIRC, you hold option key while booting then select the drive.

    You also need a wired keyboard.

    What kind of connection are you using from the HD to computer? Didn't Tiger only support booting from FW?
