So I think there should be some options or settings for the tools to create the ISO file.
This ISO was assembled from the standard Windows ISO through DISM to include NVME and USB3 drivers. However, I can't go back to this process as it was quite laborious (I did it a couple of years ago).
So there I guess there is no chance to make it "somehow" bootable or burn a new ISO from the Rufus USB-stick?
