I just installed ubuntu(hardy 8.04) into my external hard drive and I am trying to boot ubuntu from that external hard drive on my imac but every time i pressed C, command-option-shift-delete, command-option-shift-delete-#, command-option-esc but nothing happens except that it loads on the mac os x.
I also tried pressing the option key and all i get is a choice between mac and windows but nothing else. Is there a way to access that external hard drive while booting? And I would prefer a mac user to answer this question or ubuntu user to answer this question.


NOTE: I DO NOT KNOW HOW TO ACCESS THE BIOS ON A MAC OR IF ITS POSSIBLE TO DO SO.
so if there is a answer with BIOS please be very specific. THANKS
MAC or UBUNTU users ONLY PLEASE!!!!
