Best way to install Ubuntu?

I have been trying out ubuntu on pc with Wubi but I have heard that it isn't very good way to install ubuntu.
So I would like to know the best way to ubuntu along side with windows 7. (not yet ready to abandon the microsoft ship :D)

Get the iso on a usb drive, boot from it and choose "install ubuntu next to windows" or sth. like that.

Ok thats what I thought: Thanks!
