Well, at least for me with a halfways modern EFI it boots to some Debian
software.

- What kind of firmware did you try ? What mainboards or laptop models ?
- Is always the same DVD drive used for the installation attempt ?
  (E.g. because is it attached via USB.)
- How far does the DVD boot for you ? Do you see indications that GRUB
  or ISOLINUX (in case of legacy BIOS) was started ?

What i tested:

I downloaded

  https://cdimage.debian.org/mirror/cdimage/archive/11.2.0/amd64/iso-dvd/debian-11.2.0-amd64-DVD-1.iso

verified its SHA256
  022370f066bc91b2cdac3837ff5fa9f3822c5afb2fc34f68084416079fe5a408
and burnt it onto a DVD+RW

  xorriso -as cdrecord dev=/dev/sr5 -v -eject fs=32m debian-11.2.0-amd64-DVD-1.iso

Then i put the ISO into a Xeon machine with an ASUS board of 2020.
The EFI firmware offers me in its boot menu the model name of the DVD drive
for booting. I double click (it's that kind of EFI with icons and animated
CPU fans) and quite immediately see the word "GRUB" on the screen.
Then a GRUB menu appears which offers me to install. I rather choose
Advanced Options and Rescue Mode. All seems well until i want to go
back to choose another country.
It begins to talk about "Installation" which i don't want. So i press
the hardware Reset button and rather check whether my Debian on that
machine is still operational. It is. Still with fvwm. What a relief.


Have a nice dyay :)
