Alright folks I give up, google is not helping. All I can find are instructions that inform me that ubuntu needs something called REfind in order for the mac motherboard to boot off of that drive. Whenever I try to install REfind in the teaminal, I get an error message saying that I have SID enabled and that I need to restart inside the command prompt and enter a code to get Unetboot to work. The problem is I don't have a mac keyboard lol... Surely there's a way around this? I'm not familiar with SID. Is there an easy way to disable this?
