Installing Windows Vista (Veeesta) with Ubuntu

is not as easy as I had first thought. Today was the second time that I tried to install vista while having Ubuntu already installed, and I have come across a problem for the second time. I can't get windows to like the partition! I did a little research and it seems that Vista will not install onto a dynamic partition, whatever that means.. from what I've gathered (or figured out, rather) is that because when I first decided to install Ubuntu, I created two partitions, an Ext2 (which is what linux installs on) and an extended partition, which I then split into two: a Swap and extra space. Well as it turns out (correct me if I'm wrong, Jake) I should have created three partitions, the linux, swap and an empty one. I'm not exactly sure what my next course of action should be.
