installer search disk for iso file, can't find suitable one, and display
"No kernel modules found" screen
does your installer find your iso file? or do you really install via
http? network connection isn't needed if you use hard disk installation
method, with debian-11.6.0-amd64-netinst.iso you can install bare
minimal debian system
