Uninstall Win2K Advanced Server

I recently purchased a used MCSE study guide and installed Win2K Advanced Server on my laptop so that I could self-learn the 2000 Server course. My laptop already had Win2K pro and Office 2000 pro installed. I must have been brain dead because I installed the server software with out partitioning my disk. Now 2K Advanded Server is my OS. How do I uninstall Advanced Server so that I may install the server properly?
