Can I rename the startup disk?

I am running both WinXP and OSX 10.4 on my MBP. when I bootup I want to rename my Drive / startup disk name for the windows disk and just can seem to figure it out. Can some one tell me where this informatiuon is stored?

You can rename the Macintosh HD. It's the Home (user accounts) you need to leave alone if you don't want to experience big problems. There is a way to do it and Apple posts about it in their Support webpages but you cannot manually change the name of user accounts.
