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 :) Thomas
