Other than with legacy BIOS, EFI looks for different boot programs in the
EFI System Partition's FAT filesystem:
i386:  \EFI\BOOT\BOOTIA32.EFI
amd64: \EFI\BOOT\BOOTX64.EFI

debian-11.7.0-i386-netinst.iso only offers BOOTIA32.EFI :
  mount debian-11.7.0-i386-netinst.iso /mnt/iso
  mount /mnt/iso/boot/grub/efi.img /mnt/fat
  find /mnt/fat
So a normal amd64 EFI will not consider booting it.

The MBR code for legacy BIOS should be usable for 64-bit and 32-bit
alike. But Rodolfo Medina's machine seems not to like the USB stick in
CSM mode.


Have a nice day :)
