How to create a Windows NT 4 Boot disk.

How to create a Windows NT 4 Bootdisk

A bootdisk can be used in the event of an operating system boot loader failure, boot sector virus (rare these days) or accidental wiping of system files to allow a user to regain access to an operating system.
Creating one for the DOS/Windows 9x family of systems is very easy, a tickbox option in the floppy disk right click format screen, but it is not so obvious on Windows NT 4.

To do this:

1. Format a blank floppy disk (or one you don't mind losing the contents of) on a PC running Windows NT workstation
2. Copy the following files to the floppy disk:
C:\NTLDR
C:\NTDETECT.COM
C:\BOOT.INI

3. If the computer in question has a SCSI based hard drive, then copy C:\NTBOOTDD.SYS on there as well. (This is a copy of the SCSI adapter driver used by the boot loader).

This is all you need to do.

Note that this floppy will be limited to systems with your particular version and service pack of Windows NT 4, and hard disk partitioning layout (and SCSI adapter if you need one).

To boot from it, just put it it into the floppy disk drive and start the computer up.
