My guess: New hardware.
Thx for the response - I do appreciate. The device being installed is a virtual machine in KVM, which has deployed previous Debian distros without issue. I believe the "installation media" not being detected is related to changes between Buster and Bullseye - but I can't seem to find any changelogs on what has changed.
Please report back how a manual install goes. As in: Share with the community
wether or not it is a netboot / preseed problem.
Manual installation from the same ISO works fine.
