#56 Booting from USB


I'm running a MacBook 2,1 and trying to boot from USB--everything goes as planned when loading rEFIt, (Refit recognizes lilo OR grub, tried both)

However, when I select my USB drive, I get this error:

Booting Legacy OS
Starting legacy loader
Using load options 'USB'
Error: Not Found returned from legacy loader
Error: Not Found from LocateDevicePath
[......above error 13 more times.....]
Error: Load Error while (re)opening our installation volume

Then some garbage about macs not liking legacy OSes on external drives.

I'm not the only one with this problem, but I've been bashing my head into the wall over and over again trying to get it to work. Can you get this fixed so the LocateDevicePath bit works? I'd try a firewire drive, but I don't have one :-(

    With iMac I have the same problem. I have no fix to this, but a workaround: I created a boot CD to boot Linux that resides on the USB hard drive. This is not much, but anyway lets me boot the darn thing.

    The "garbage about macs not liking legacy OSes on external drives" is a message I specifically put into rEFIt to tell you that USB drives are not supported by Apple's firmware, and this cannot be fixed from the rEFIt end.
