To install W2K on a computer, you will need a usb containing an imaged ISO of FreeDOS (the lite version) (found here: http://www.freedos.org/download/download/FD12LITE.zip), Windows 2000 Files (extracted from the ISO here: https://winworldpc.com/download/413ce280-9436-18c3-9a11-c3a4e284a2ef), IDE HDD or an option to emulate IDE from SATA in the BIOS, Drivers (that are compaitible for Windows XP or below), Modern Software Compaitiblity (downloads here: https://drive.google.com/drive/folders/1NJfVNy6yqVavchfjoz8iTyj4j3C-Z9oa?usp=sharing) (tutorial here: https://youtu.be/F-1pIl-Wdzo), and time.
Step 1: Boot FreeDOS, and install it onto your hard drive (this will take a few minutes)
Step 2: Go to another computer and format the drive
Step 3: Copy all the files from the Windows 2000 ISO you downloaded over to the USB
Step 4: Eject the drive and plug it back into the 2000 computer, turn it on, and get to the DOS prompt
Step 5: Type 'D:' to get to the drive and then go to the directory 'i386'
Step 6: Type 'winnt.exe' to start the DOS setup, follow the on screen prompts (this may take a while)
Step 7: Restart the computer once it is done, then follow the on screen prompts on the setup. Keep everything to the default.
Step 8: Once it is done, restart and you will be welcomed with the Windows 2000 first boot screen.
