Installing Windows 7 without disrupting Ubuntu

[scarflash]

Hey,
I have Ubuntu 8.10 installed and i'm trying to install windows 7. Unfortunetly I don't have a dvd drive, but I have downloaded the iso. Is there a program that can create a partition for windows 7? If so what do I do to install Windows 7 in that partition? I've started backing up my programs since I barely use my Ubuntu desktop anymore but I wouldn't like to waste time backing up and restoring.

Thanks!

I don't know the specifics, but the Windows 7 iso was designed to make it possible to install it off a USB drive as well if you have one large ebough.

There are tutorials everywhere about how to do it.
