I have the following "setup:"
iMac (no internal drive/dead) --------- (Firewire) ------- [[MAC OS X]] | | | | (USB) | | | | [[MISC STORAGE PARTITION] [MISC STORAGE PARTITION] [EXT2 UBUNTU PARTITION]]
I routinely use the firewire drive to boot MAC OS X.
However, I would like to boot from the linux partition of the USB drive. This linux partition had linux installed on it from a live cd, and during that process, I told the installer to install GRUB on the usb drive (which happened to be /dev/sdd).
My question is, how do I get this disk to show up during the iMac option-boot? Currently, only the firewire MAC OS X option shows up. I have read about rEFIT, but that appears to install it to the Mac OS X disk (would that still work?)...
Also mentioned was installing rEFIT to the internal EFI system partition, but I don't know if that is wise.
