Problem booting Linux Mint 15 Live (USB and DVD)

view story

http://www.linuxquestions.org – I'm tying to boot LM 15 live on my 2.66 GHz Intel Core 2 Duo MacBook Pro 5,1. I can get it to show up on Refit and Refind, and the countdown screen shows up but it gets to the next screen and freezes. I tried using different methods to install it but i get the same result. I even tried to use grub 2.0 to boot it, but it tells me to load the kernels first. So i try to find forums that loads kernel manually, but keep coming up with errors. So I'm out of ideas and need help. (HowTos)
