Unable install NT4.0

Recently wiped Win98se off of hardrive. when running NT setup cd, ‘Unable to setup or install NT Boot Loader during setup’, will not allow set up to continue. Recently repartitioned primary partition 2500M and then reformatted harddrive. Is a PentiumIII 450 with 2G harddrive with 64M ram.
Also did a Fdisk /mbr. Ran Scandisk previously with no errors indicated. Ran utility, scanreg I believe, indicated system file(s) problems and suggested clear some files off of harddrive (spacing issue??). I believe the system file issue cameup when I previously tried to install Win98se and did happen during the final reboot of the final phase of the Win98se install. At that point I decided to reformat and install NT 4.0. Open to all suggestions.
