If you use winnt or winnt32 with the /o option, boot floppy disks are created that require the presence of a local source directory with the installation files. You can create boot floppy disks that do not require this local directory (using retail installation media instead) by using the /ox option. This is preferred if you are installing from a compact disc rather than over the network.
In no case does the winnt or winnt32 command create boot floppy disks that can install Windows NT Workstation or Windows NT Server in its entirety.
