Creating a dual boot.

To Whom It May Concern:

I have a Hewlet-Packard 740N Provilion PC. The computer came with Windows XP Home Edition installed on it. There is currently a hidden partition on the C Drive that has all of the recovery information for Windows XP Home Edition on it, and the partition that supports Windows XP Professional as well. How can I get rid of the hidden partition? If I can’t will that interfere with the dual boot process, how can I create a dual boot using Partition Magic 7 to supportboth Windows 2000 Professional and Windows XP Professional on my computer?
