If UEFI was enabled, the USB device isn't seen by the machine in its

I downloaded this:
debian-bookworm-DI-alpha2-amd64-netinst.iso
from here:
https://cdimage.debian.org/cdimage/bookworm_di_alpha2/amd64/iso-cd/
and I wrote that .iso to /dev/sde
I did "cp debian-bookworm-DI-alpha2-amd64-netinst.iso /dev/sde"

then I could at least get this working after some fiddling.
