After updating Windows critical files, and rebooting the NT workstation I received the following message STOP: MISSING SYSTEM FILES
The required system file Display_driver.dll is bad or missing. MS tech site is suggesting a parallel installation of Windows NT and start to that installation... I'm not sure how to accomplish this, can anyone help? I'm not receiving a DOS prompt, so I can't cd into the correct directory for copying?

Thank you in advance for any help you can provide.

Installing a parallel installation means to boot using the NT setup disks. The setup will detect the existing installation and ask you if you want to install NT in another directory (like winnt40, for example). Once installed, your startup screen will look something like
WINNT
WINNT (VGA)
WINNT40
WINNT40 (VGA)

You will want to select the Winnt40. Once you're in, you can install the same service pack that was on your original installation, and then copy the missing files from the new install to the old install.
