My friend's Mac is pretty much gone and I want to boot into Ubuntu to try and get some info off before I re-install Mac OS X.

I heard that you need something called rEFIt to boot Ubuntu on Mac hardware but how would I use that?

There is a program called Linux USB Creator for Mac. The program will allow you to download the necessary ISO, carry out any necessary formatting, copy the ISO and install the bootloader. Boot up your mac while holding the “alt” key and select the drive corresponding to your usb stick.
