[xubuntu-users] Unable to Boot Xubuntu 12.04 Live CD

[David Emme]

I have a MacPro 1,1. I downloaded the Xubuntu amd64 12.04 Live CD from 
http://mirror.anl.gov/pub/ubuntu-iso/CDs-Xubuntu/12.04/release/, but 
cannot boot it. I get the (apparently) well-known "Select CD-ROM Boot 
Type:" problem, and cannot proceed from there.

Research indicates that my older Intel Mac has an EFI conflict with this 
CD. I had the same problem with the Xubuntu 11.10 CD; the Ubuntu 11.10 
CD boots on my machine just fine.

I see the apparently required "+mac" ISO image for Ubuntu, but none for 
Xubuntu at the above URL. What am I missing?

TIA,
-Dave
