Hello, new here. So, I am not a huge fan of mac, but unfortunately at my school we have to have them. So, I decided to dual boot ubuntu. Now, I burned an image of it onto a dvd after installing rEFIt. I also created a partition for it, trying several different formats. So, what happens is, I put the disk in, restart my computer, see the linux icon, press enter on the linux icon. Then it just goes to a black screen with a blinking text input. that's where it stops. It doesn't do anything else (and trust me, I've waited), and it won't let me type. Just nada.
