You could install a lower edition and then change the edition upwards. But you say you haven't updated those so it would be pointless.
My suggestion is to start over again.
Make sure your antivirus is disabled when running the script.
To make it faster and smaller, don't slipstream the updates. Only add the drivers (USB and MVMe) to ALL editions.
You can install the updates after the installation running UpdatePack7R2
