Hi all, I'm currently trying to get ubuntu 12.10 installed on my external hard drive. I put it on one partition on the disk and installed it with a live CD. My computer is a 2012 MacBook Pro retina 15", and I have refit installed. Whenever I try to boot from the installed Ubuntu, my computer instead boots into my Windows 7 bootcamp partition. Any suggestions for fixes? On a side note, I opted not to create the 1 mb boot partition suggested during the installation.
