boot from a cd
Hello, I installed linux mint on my 2010 macbook pro a while ago and it isn't really what I wanted. So I decided to install Arch on it. I downloaded the .iso and burnt it to a CD and put it in my laptop and restarted, however I can't get it to boot. I get the white flash screen from the mac then I get the black grub boot loader option menu, where I can boot linux mint, linux mint recovery, or two memory tests. I tried to use grub customizer but I couldn't figure out how to make it boot from a CD.
Does anyone have any idea how to make grub boot from a CD?
Thanks for any help or advice you can throw my way.
