I got Ubuntu - FINALLY - on my machine.
My main reason was to have a faster OS and a machine that could easily read HFS drives and FAT32 at the same time.
Also, everything else I used was compatible with Ubuntu (Linux) - except, it seems, minecraft.
I'm having a hugeee issue trying to get it to install. I am such a n00b with linux, so if you could hold my hand whilst I swing in the play park I would appreciate it.
