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 :) Thomas
