I am trying to upgrade to Snow Leopard 10.6.3 from Tiger 10.4.11 with an external DVD drive. The disc loads OK and prompts me for my password to restart and begin the installation. On restart, instead of being asked to accept the terms of use and etc... I just get the same prompt to restart and get caught in a loop. Any tips?

    Try this instead:


    Boot Using OPTION key:


      1. Restart the computer.

      2. Immediately after the chime press and hold down the "OPTION" key.

      3. Release the key when the boot manager appears.

      4. Select the disk icon of the Snow Leopard DVD.

      5. Click on the arrow button below the icon.

    Then your external drive is not recognized as being bootable or your Snow Leopard DVD is defective. From where did you get the DVD?
