Does anyone know how to restore my iMac HD using SuperDuper? I am unable to start up to my backup external hard drive, I don't see how I can restore using Utilities. HELP!!

iMac, Mac OS X (10.6.3)

    If your clone is on the external drive and it won't boot, you can't use it to restore.
    What is wrong with your internal that you need to restore? Or, do I have it wrong?

    How are you trying to boot from your external?

    If the computer is working OK, use System Prefs to chose your startup disk, choose and boot from your external and run SD from there. Clone backwards.

    If problems booting your Mac, hold the Option key down at startup; when your HD appears, wait a few secs and your external should appear; select the External as your startup disk, then run SD from the external back to your Mac.

    I held the "option" key while starting, the clicked on the external drive to start. Came to a window that instructed me to go back and select the HD to start.

    If perchance you are using a wireless Bluetooth keyboard it might be helpful to plug in an old USB keyboard if you are having trouble making boot drive selections by holding down keys when rebooting.

    First off, as has been asked, what's wrong with your internal HD? Which iMac are you using? Is your external HD connected via Firewire or USB?

    Is it possible to copy from the back up?

    Do you have a bootable clone on your external that you made with SuperDuper and tested prior to this to make sure it was bootable?

    Is your external bootable?

    Somehow you've got to make it the startup disk to clone back.

    Everything froze this morning. With the help of Apple Tech, I was finally able to boot using my install CD. Ran disk repair and received a message that there was a problem and I would have back up my hard drive, erase my hard drive and restore.

    When I back up using SuperDuper, it runs through a series of things, including making the backup a start up drive. I just assumed that it would work when I needed it. Guess I was wrong.

    OK.

    Had that problem recently.

    Do your clean wipe. Get your Mac bootable. Then don't do any updates - just boot into your external, and reverse clone SD from there. The wipe should take about a minute or two; the clone back an hour or more depending on the size of your useage (200gb took an hour and a half approximately a few days ago to fix a similar problem on a 6 month old MBP).

    Post back results.

    pcbjr,
    I'm not sure I understand. Why would that work?
  • Marjean54 Level 1 Level 1
    I understand. I updated to 10.6.3 after backing up to external drive. That may be the problem? I'll see if it works.
  • pcbjr Level 2 Level 2
    If I understand correctly, you have a SD clone that predates 10.6.3.

    If that's the case, once you wipe and get a bootable Mac, and then startup from your external, SD should be a breeze.

    If your SD backup is post 10.6.3, and if the problem surfaced after your SD 10.6.3 clone, you may be cloning your problem back to your Mac.

    Assuming the former, once you're up and running, use the standalone Combo Updater to go to 10.6.3.

    Keep us posted.
