• If you want to reinstall Windows NT onto the HDD that has been used for Microsoft Windows 2000, Microsoft Windows 98 or Microsoft Windows 95, the Windows NT installation program might not recognize the partitions generated by the Windows 2000, Windows 98 or Windows 95 Fdisk Utility. Use the PC-DOS Fdisk Utility instead.

Installing Microsoft Windows NT
NOTE: If you have an external CD-ROM drive that connects under a DOS environment, you can install Windows NT in DOS.

1. Insert the Windows NT CD into the external CD-ROM drive.
   
2. Open a directory for the CD; then go to the \I386 directory.
   For example, if your CD-ROM drive letter is D, go to D:\I386
3. At the command prompt, type WINNT and then press Enter.
   For example, D:\I386>WINNT
4. Install Windows NT by following the instructions on the screen.
5. Next, install Windows NT Version 4 Service Pack 6A.
   After you install Windows NT, you will need to install the device drivers.

If your computer does not have a CD-ROM drive, you can use a network server. You can install Windows NT on multiple computers by first copying the Windows NT master source files to a shared drive on a network server. After connecting your computer to a network, such as with the DOS LAN requester, you can install the files from the network server to your computer at the DOS command prompt.

For more information, refer to the installation guide of Windows NT or Windows NT Version 4 Service Pack 6A.
