I spent the past few hours getting the Debian installer to finally boot from a USB drive. I had to install rEFIt to get that working. So I installed debian, deleted the Mac OS X installation in the process, and now I can't boot into Debian because rEFIt is no longer on the drive since it got erased with Mac OS X it seems. So now I have a Macbook with no CD drive, and no bootable operating system.
I've got a USB flash drive, a windows PC, and a linux PC at my disposal. How the heck can I fix this?
I want the final product to be a Macbook with Debian on it, and nothing else.
