I use a MBP and am running Parallels. I currently have it set up with a Windows XP partition on my internal hard drive. Now what I wish to do is set up a Linux partition using Ubuntu. I know this is possible using Parallels but becuase of hard drive space I don't want to put it on my internal drive. I have a external firewire hard drive that I wish to use. Is it possible for me to set up this Parallels partition to also have a Ubuntu partition and as well have it on a external hard drive? Where can I get instructions on how to do this? Thanks in advance for help.
