Comment # 5 on bug 1208918 from Stefan Hundhammer

OK. I never used that Ventoy, so I have no idea what exactly it does.

https://en.wikipedia.org/wiki/Ventoy

But what ISO from where (exact name and download URL, please, and also
approximate ISO size!) did you use?

Was it a NET ISO which only contains rudimentary data to start the installation
and from then on downloads everything from an Internet server?

Or a normal or full ISO which already contains RPMs?
