NT 3.51 (and 4.0) was always VERY touchy about boot devices. If it happened to have loaded the right driver all was well, but if it moved to the next phase of setup and the right driver is not loaded then this is what happens.
How was the installation started? With boot diskettes? or invoked from DOS? I found that if you have the source files on a CD or something there wasn't an NT driver for that launching from DOS with the command to copy all the files to a FAT partition first could be a workable plan. You can always convert the partition later using the convert command (assuming NT 3.51 had that already).
