Can’t See hard drive

I am trying to ‘re-load’ a Toshiba Portege 3440CT laptop (this is the ultra thin model – no internal floppy or CD. The floppy connects via USB and the CD via SCSI.) The BIOS allows for boot selection including CD or Floppy. I have done a ‘Fdisk’ and ‘format’ successfully and can boot to a ‘C:\’ prompt. I am trying to load 2000; I have a bootable CD and it reads from the CD, doing all the preliminary system checks etc.; then I get the prompt to Install 2000 or Repair 2000 or Exit; I press Enter to Install 2000 and I quickly get a message that 2000 cannot find a hard drive press F3 to quit. Anyone got any thoughts on why this would happen or what I can do?
Thanks.
