Cannot Rename Partitioned HD

Hi:

I've just installed Boot Camp and Windows XP Pro on my Macbook. After the installation was completed, I rebooted the machine to start up with OS X and I've notice the newly partitioned HD icon on my desktop next to my Macintosh HD icon. Now I would like to rename this Untitled HD to Windows HD but cannot find a way to do so... Did anybody encounter this problem after installing Windows XP through Boot Camp?
All input is welcome.

Nevermind I got it. If anybody has a similar problem you can rename that "Untitled" HD to whatever you want it to say by renaming the C: drive in Windows XP.
