When I use the Diskpart tool and Windows Preinstallation Environment (WinPE) to install Windows Server 2003, why do I receive an error stating that no valid system partitions were found?

A. You might receive an error stating "No valid system partitions were found. Setup is unable to continue," if you use Diskpart before executing the winnt32.exe file. To resolve this error, edit the installation script or batch file and add the

/syspart::

parameter to the end of the winnt32.exe command. For example, to specify drive C as the system partition, type

winnt32.exe /syspart:c:
