Why can't NT 3.1 be installed? - China DOS Union Forum - China DOS Union

The winnt.exe of nt3.1 without /b and without /ox, can only install directly with winnt, and need to make installation floppies before installing.

Everything went smoothly during the installation, but just when I was feeling proud, a dialog box suddenly popped up. At the moment when the nt startup was completed, the mouse was already visible, and the installation program was about to appear in the graphical interface. My heart suddenly became extremely cold.

The general idea is that nt cannot support this processor, and the installation cannot continue.

Common knowledge for installing NT 3.1/3.5: You need to modify the INF to add support for new processors. Otherwise, you can only install on computers with CPUs below 586.
