When booting an ISO file I wanted the installer to ask what product edition to install.

Do the following to make this happen:

Create a file called ei.cfg

put this in the cfg file:


I then used a free program called AnyBurn to copy the file to the sources folder in the ISO image

The Official AnyBurn Website

After that I copied the modified ISO file to my Ventoy folder

If you are unfamiliar with Ventoy I highly recommend it as it lets you have several ISO files on one USB stick and you can boot any one of them
