It sounds like you let Windows create one large partition when you installed it (the default behaviour).

I'd suggest some sort of partition manager like Partition Magic, but since you've only just got the computer it might be easier to simply delete the partitions and start from scratch.

Boot from your XP CD, and when it asks you if you want to set up partitions, say yes. Delete all existing partitions, then set the C: partition to whatever size you want. You can leave the rest of the space unallocated for now, then when you finish installing, go the the Disk Management console you already tried, and you'll have two sections, C: and unallocated space. Once here you can follow the instructions in the help file.

You might not need to shell out for Partition Magic, you should be able to boot to a command line console from the XP disc; choose the Recovery Console, and when it loads (takes a minute or two), run the XP partition program, called Diskpart if I recall correctly. You'll delete all your data, but it'll save you a bit of cash.
