Finally I came across this blog post which refers to a super easy method for making bootable USB drives that comes from some German forums. Creating Bootable USB drives using standard methods on the Ubuntu website didn’t seem to work either. My Mac Mini has a busted Superdrive, so booting from a DVD wasn’t an option. Below are the steps I went through to get this working. Finally I got it installed after picking up some tips from a few forums.
This was a nightmare to finally find a method that works, as the standard documentation from the Ubuntu website did not apply to my machine. Due to the lack of support for newer Mac OS’s on older Mac Minis, I opted to wipe my mac and install Ubuntu over it.
