You can't as there's no /s switch available in the Format command and there is no DOS layer to fall back onto anyway.
On your W2K installation CD there is a folder called BOOTDISK. You'll find an .exe file in there that creates the four book floppies required to get the W2K installation going.
Or you can boot directly from the W2K CD if your system supports that feature.
Or finally, you can go to www.bootdisk.com and download a boot floppy image.
