How can I create a backup disk image of a MacBook before I start the first-run process? Is there any way to create an image of a brand new "unconfigured" MacBook?  I want to get an image of this box before the OS installs just in case I have any issues.
If you have access to another Mac and the necessary cable, you could boot your MacBook in Target Disk Mode (hold down the T key when powering up). Connect via Firewire or Thunderbolt to another Mac. The drive on the machine in Target Disk Mode can then be cloned.
