Cam. Is win7 in a separate partition on its drive? Is there a reason why you want it in a partition?
Personally I like to put the OS on a separate partition so I can re-install the OS without worrying about the data on the drive.
I havn't done a win7 install, but vista gave me the option of creating a partition during the install process. I've installed xp so many times at work I can't remember, but I expect it gives the same option.
You can manually edit the boot.ini. Its just a text file, but you would need to know what to put in to get the boot menu to show up. A quick online search will probably give you the appropriate entries.
..., or you can do it the easy way as Peter suggested
