I have just installeed bootcamp and windows xp and that is working perfect on my mbp, i am wondering how to boot ubuntu from a live cd? i thought i had the live version downloaded, i burnt it onto a dvd disc with toast but when i restart my mbp and hold option i just get windows and macantosh for os's. then i try restarting and holding c and i just boot in osx. can someone tell me what i am doing wrong, or if i did not download the correct distro ?
