Want to install Windows 7 RC1 with boot camp

I have the Windows 7 RC1 and I want to use boot camp but I have a couple of partitions that need to be removed. When im in disk utility I try to remove the partion but it just sits there and the progress bar does not move. I am on the road and dont have my install disk, is there anyway to boot into disk utility so i can delete the partitions withou the install disk?

any help would be greatly apprecited!

Your best bet would be to wait until you are home and have your install discs so you can do this properly.
