I need to run Ubuntu 11.10 for my diploma thesis, but all i have is a MacBook Air (bought last year). I want to boot Ubuntu from a Live USB in order to install it, but all i get is a black screen. Here is what i did:
I tried creating the Live USB using these instructions: http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx But OS X Lion couldn't load the USB drive afterwards.
I then used http://penguintosh.com/ to create the Live USB, which seemed to work fine.
I held the alt / option key while booting, then selected the Live USB. I got some white letters on black background telling me "Fasten your seatbelts, loading kernel, this may take a while". Then the screen became black and nothing ever happened.
