Note that I'm using Disk Utility on 10.6 and I haven't worked with 10.4 in a long while. Make sure Erase destination is checked and double-check that you're dealing with the right partition. Then go to the restore tab and select the DMG for the source and the new partition for the destination.
Once you have the DMG, rather than using diskutil at the command line, just use Disk Utility and create a 10 GB partition at the end of your drive (under the Partition tab for your drive). Funny idea: go to an Apple Store with an 8 GB or higher USB stick, buy Snow Leopard, then use one of the computers there to create the DMG. You need to back up the entire hybrid disk (at least for 10.6).Ĭan you access another Mac to do this? If so, in Disk Utility select the drive (not the volume) and click the New Image button on the toolbar to save a DMG as a DVD/CD Master. There is a thread that discusses using IsoBuster to create an image.
