Hello, I am trying to use a LiveCD of a newer version (at least 12) of Ubuntu on my MacBook Pro. 10.04 works fine. But when I burn 12.04 (desktop i386) to a DVD the disk is unreadable.
When I reinsert it, it says "The disk you inserted was not readable by this computer." When I boot up, I can select the disk for startup but all that appears on the screen is a blinking cursor.
It's almost certainly not a problem with the DVD; I've tried this multiple times. Please help, I am running out of ideas. Thanks.
edit: It's a mid-2012 model.
