Installing Ubuntu 11.04 As We Speak. Need Help. Used UNetBootin

[Viva en Grey]

Alright, so I originally had a very detailed post typed out..but I lost it, so I'll keep this short & sweet.


1) I'm using UNetBootin as my installation method to install Ubuntu 11.04

2) I have successfully booted using UNetBootin, and now need to officially install Ubuntu.

3) For clarity, I'll use some images to guide through. Here's where I have started-- on my desktop is the icon for the installer of Ubuntu, highlighted.

4) After clicking the installer, I am asked what language I would like, and am then shown this screen.

This is where I am kind of lost. I know that I am running Windows Vista Home Premium 32-bit, and have ~60 GBs of files, programs, etc. I'm not sure what drive I should select to go onward, or what I should do at all from this point really. I would not mind completely installing Linux over Vista, but keeping my files is a definite must. Help, anyone?

Thank you, and of course, I'm here to provide any & all screen shots and info needed!!
