I'm trying to boot into a macbookpro (4,1) using the liveCD to install gdisk and solve my multi-boot MBR issues.
Using gdisk was tedious via OSX (only working OS right now) and as yet my ubuntu partition is useless space.
I can't "try ubuntu before installing" with the liveCD as it takes me to a black screen on my mac, nomodeset seems to load the drivers but it's welcoming me to Ubuntu 11.10 via command line - it won't boot into a graphical environment and I'm not sure why.
The final line displayed is Welcome to Ubuntu 11.10 (Linux 3.0.0-12-generic x86_64) with a
ubuntu@ubuntu:~$ cursor, and the liveCD boots into a GUI fine in another PC.
