How to resize 2gig Dynamic Volume

OS:Windows 2000 Server
I have change my boot dive from basic to dynamic volume in order to configure a mirror set. I did not save the configuration set. The boot drive is a 9gig, partition 2gig bootable. I like to increase the 2gig to 4gig. PartitionMagic does not work on dynamic volume. I cannot go back to basic volume, because I did not save the configuration. How can I get this done. Help???
