Dynamic disks are not supported on the following hardware:

Dynamic disks do not use traditional partition tables like primary and extended partitions (logical drives); therefore, dynamic disks cannot be accessed by MS-DOS, Windows 95, Windows 98, Windows Millennium Edition (Me) or Windows NT operating systems.
