Boot from the the floppy disk with NO cd rom support.
Make sure that there are two partitions in FDISK, the main one with Windows on it, and another one that should be blank. If you have only one partition, use the empty space and create another partition using all free space.
Quit fdisk, reboot from the boot floppy again (be sure to choose no cdrom support)
Try to access your C drive with the C: command, run DIR, and ensure that your C drive is there, with the WINDOWS directory and all that.
Next try to access your D drive - you should get an error that the drive is not ready, or something like that. If you get no error, and the D:\> prompt appears, run 'dir' and ensure it is blank.
Type the following: 'Format D:', this should format the new partition in dos, it'll likely take around five minutes.
Reboot into Windows, and the drive should be there. There is no need to format the drive in Windows, since we already did that in DOS.
(Usually your D and E drive would be your CD/DVD drives, but since we had no cd-rom support in DOS, it simply assigned that letter to the new parition, temporarily.)
