You have been really unlucky, haven't you?
Does this error appear after the text setup portion of Windows 2000 Server setup (i.e. after copying files to hdd and computer is supposed to be restarting from hdd), or does it appear after the graphical interface portion of installation (by which time it is supposed to restart into W2k server proper)?
If you haven't removed 1st hdd, do so.
Check in BIOS that it's showing the correct capacity. If not, see if in BIOS there's an option to enable LBA mode or Block mode. If so, enable it.
Check if there's a BIOS upgrade for your motherboard (go to motheboard website). If it's OEM computer, check the OEM computer website.
