Hi Cyril & Steve,
Apologies about slow reply. I only just found this thread buried in my
'debian bugs' folder (I'm subscribed to bugs@debian and obviously don't
have my filters set up as they should be...).

Hi Jeremy,
and thanks for your report.
Jeremy Davis <jer...@turnkeylinux.org> (2023-04-09):
Machine: Lenovo T470 (20HD)
Had to disable secure boot to get USB to boot, but otherwise,
everything "just worked".
Why is that? We've been supporting Secure Boot for a very long while.
And one of my standard test machines here is my old T470. Jeremy: what
problem are you seeing please?
FWIW this is my first "proper" UEFI hardware.
The issue I had was that the USB stick (with debian iso copied to it) I
was using wasn't showing up in the (bios/uefi) boot options (f12) as a
bootable device (i.e. wasn't listed as an option).
I was considering trying PXE boot, but I ran across online suggestions
that some USB sticks aren't recognized by BIOS/UEFI with secure boot
enabled. So I disabled secure boot and the USB appeared! :) Everything
worked as expected after that.
Perhaps there was something else going on and it was coincidental that
it worked after disabling secure boot? I just assumed that it was a UEFI
bug(/feature?) and not directly relevant to Debian.
I haven't tried re-enabling secure boot.
Regards,
Jeremy
