Mirroring Window 2000 Server

How do I go about mirroring the system disk which is also the boot disk? I am using 2 18gb wide scsi drives on 1 scsi control. When I do an initial setup the c: drive is a basic volume. When I update it to a Dynamic volume, the system restarts and will not find ntldr when it trys to boot back up. Can you help please?
