I understand that this menu is not yet Linux but bootloader.
Since you obviously have EFI without BIOS emulation active, the bootloader
from the Debian ISO is GRUB (from BIOS it would be ISOLINUX).

So you can properly operate the menu ?
In that case it would probably not be GRUB which fails but already Linux.
A matter of the booted kernel and its modules in the initrd.

Did you already try the very newest Debian ISOs ? Maybe they have newer
Linux kernels. E.g.
  https://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/multi-arch/iso-cd/debian-testing-amd64-i386-netinst.iso

Sifting through the mailing list archive, i see a proposal by Pascal
Hambourg in
  https://lists.debian.org/debian-user/2017/06/msg00406.html
which did not yet get a reply:

This might help to determine which of both systems is to blame:
GRUB or Linux.

@Pascal:
Do i get it right that you assume the last visible menu runs already
under control of Linux ?
But i see the texts reported by Rodolofo in Debian ISOs in the GRUB
menu file /boot/grub/grub.cfg :
  menuentry --hotkey=i 'Install' {
  menuentry --hotkey=6 '64 bit install' {
  menuentry --hotkey=g 'Graphical install' {

So i assume that the last good graphics stems from GRUB and the last
user interaction was received by GRUB.
Question is whether the machine's user interface dies when GRUB ends
its life or while Linux is starting up.

If it is about the Linux kernel then Knoppix will not be a way to get
the latest Linux kernel. It might of course have a drivers which the
Debian ISOs don't have. So when it is out it is worth a try.

You could try some other distro ISOs whether you get to see at least
a few kernel boot messages after choosing a menu item. Success with
another freely downloadable ISO could help to find out what goes wrong
with the Debian ISOs on your machine.


Have a nice day :)
