The behavior is exactly the same for both ISOs. When I do: boot usb0/disk:,\\BootX It gives the error: DISK-LABEL: invalid partition # And I see that it tried: boot usb0/disk::,\System\Library\CoreServices\grub.elf Indeed, I can reproduce the error directly with: boot usb0/disk::,\\grub.elf By removing the extra ":", I can boot grub (for the grub-rescue and the install ISO images): boot usb0/disk:,\\grub.elf You have an iBook G4 so I would expect the behavior would be the same for you as well. Although our iBooks are slightly different since mine required yaboot to be loaded at a higher address. John Ogness
