The procedure is more or less the same:
- Create a bootable usb stick with Ventoy
- Copy the iso file in the empty partition created by Ventoy
- Boot "server" from usb stick
- Select the iso file
- When countdown comes, press any key to stop it
- At this point there is a different from the video (minute 1:50), probably there is a problem in our script: the procedure doesn't start, you have to launch it manually (type 1.nsh and it starts).
- Wait the end
- When prompt comes back, type "reset"
- Remove the usb stick during reboot
- Enjoy!
