In an iBook G4 running Tiger (10.4) I have a situation where I created with Disk Utility a "Restore" full backup of my system Volume to a partition on an external USB disk.
My system Volume originally had the name "vol1". After the full backup completed successfully, the partition on the external USB disk that contained it also had the name "vol1", as expected. I then renamed, in the Finder, the name of the partition on the external USB disk from its original "vol1" to "backup_vol1" (which I naively thought to be a good idea, as to having a self-documenting name for that backup partition --I was wrong!).
I am now trying to restore the full backup from the USB disk to the system Volume on my iBook G4. The restore completes without errors, but upon reboot the system gets stuck on the "gray Apple logo" screen, which is early in the boot process, and it won't progress from there. So my iBook G4 is not booting up to OS X anymore.
What can I do to unscrew my situation? I think I have all the data of the system Volume in my backup, it just seems I cannot restore a "blessed" bootable volume...
