Booting into thunderbolt drive from MBP Retina

    I have a MBP Retina display, I just bought a Lacie Little Big Disk (1TB) Thunderbold drive.

    My old computer is a MacBook Pro running Lion (Intel based MBP)
    Since my old MBP doesn't have any thunderbolt connection I booted the MBP into disk mode by holding the letter "T" - I connected a Firewire 800 cable to my retina display and the drive was mounted on the desktop.

    I used SuperDuper to create a mirror image of that internal drive to my thunderbolt drive.

    When I reboot my Retina MBP I hold the "option" key and I see the drive I've mirrored. When I selected I get a circle with a slash through it right in the middle of my screen. Do not pass go, do not collect $200...

    I've also removed the RAID that comes with the Lacie Drive and have made the backup copy to one of the two drives in the Lacie with the same problem...

    Any help would be greatly appreciated
    Is it because the bootable drive isn't running Mountain Lion? What am I doing wrong?

    make sure your older Macbook Pro is running 10.7.5 or 10.8.x

    Older versions of the OS did not support the Macbook Pro w/retina display.

    The 10.7.4 that shipped with Retina was a special build; it is not the same as the 10.7.4 general release.

    Also, make sure your LBD is partitioned as GUID, and the volume format is Mac OS Extended, journaled.

    I used Apple Disk Utility from the Retina to format and partition the LBD, and its System Restore to clone the image. This is necessary to build the recovery partition correctly.

    If your older Macbook Pro is running an earlier version of the OS:
    - make the clone to the LBD
    - update the clone with the 10.7.5 Combo updater when booted from the MBPr internal drive; apply updater to the cloned drive

    Then you should be able to boot.

    Thanks g4cube!

    When you created the clone using the Disk Utility Restore function, did you make a copy to the RAID stripped array or to an individual disk?

    I was not running the latest version of OS X, so I've updated but I can't seem to use the Restore feature for the RAID array.

    You need to:
    - boot to the Restore partition (Restart and press/hold Option Key)
    - run Disk Utility while booted from the Restore partition
    - confirm that Little Big Disk is connected annd visible as the original LaCie formatted RAID volume; if you wish, you can use Disk Utility to reconfigure the RAID into two separate, un-RAIDed drive volumes
    - Use System Restore, with Source as your Original Macintosh HD; Destination as the LaCie volume
    - click on Restore, and wait until completed

    You'll find that when you restart after completing, that Disk Utility actually copied both your Macintosh HD volume as well as the Restore volume. The Restore volume is visible if you use the "diskutil list" shell command in a Terminal window, or when you Restart while pressing the Option key. All bootable drive choices will appear.
