Trying to install Ubuntu on a partition because my virtual machines got messed up when I upgraded to Lion and I don't feel like messing around with 'em . I don't want to use boot camp because I want a partition smaller than 20 GB (which is the minimum) so I decided to use Disk Utility. I understand basically how to partition but haven't in a while and can't quite remember some stuff. What format should the partition be? Also, how do I install the iso to the partition when it's done? Any help would be great, thanks.
