I'm sure this has an easy fix, but I don't want to mess anything up. So I just now have put Ubuntu onto my laptop (sort of). I want to install it alongside windows, but I couldn't get the Microsoft installer to work. So I burned a disk and now Ubuntu is on my computer. I still have the disk in my computer and it's on the "demo" mode. When I go to actually install it, the installation wizard says I have multiple operating systems on my computer and it wants me to choose a partioner. Or something like that. Please solve my problem magic person. (btw the software versions: windows 7 and Ubuntu 12.04)

I would strongly recommend you follow the guidance on the Ubuntu website here for dual booting if that is what you would prefer. It looks fairly straightforward to me.
As you will see they indicate that there is a default install side by side option which unless you know what you are doing (I don't!) I would follow their advice:
Let us know how you get on :-)
