They are nothing alike, except they are operating systems

No, easier: just download the CD image, burn it to a CD, put it in your computer while in windows. An Autorun dialog will popup. Choose "Install on my computer without changing windows" or something like that. And it will install Ubuntu on your computer. Restart your computer. A menu will pop up asking you if you want to boot into windows or Ubuntu. Choose ubuntu. Follow the onscreen instructions for finishing the installation. And poof. You're dualbooting.
If you don't like it, you can uninstall it by booting into windows, and uninstalling it from the Add/Remove Programs option in Control Panel.
