Safely upgrading the basic drive to a dynamic drive

I recently installed a Windows 2000 Small Business Server. The main drive 0 was a basic drive with two partitions (one for the OS and the other for data). A second dynamic hard drive was present. I tried to mirror the second partition on the main drive with the second hard drive. I tried upgrading the drive one to a dynamic drive, but when the server rebooted it stopped booting up into Windows 2000. I had to reinstall the whole thing over again. Is there any way of upgrading the basic drive to a dynamic drive so I can mirror the volume safely?
There may be several reasons for why this didn't work -- the size or location of the partition, for instance. Before changing from basic to dynamic disk, make sure you have installed all Service Packs and hotfixes, as certain drive geometries may require the most recent updates to work correctly.
