You need to use FDISK to delete all the existing partitions and create a new one. You need to copy the FDISK command unto your boot floppy and run it from there.

Also note that FDISK'n' will make any existing data on the drive inaccessible through normal means. If there is data on the drive you wish to keep, you will need to use a partition editor like PartitionMagic (http://www.symantec.com/norton/products/overview.jsp?pcid=sp&pvid=pm80) or Parted (http://www.gnu.org/software/parted/index.shtml).
