I also have an Asus motherboard, but for Intel hardware. In your BIOS secure-boot page, do you have a section called Key Management? When I was working on getting my machine to boot, a year ago, I was advised* to hit the item "Load default keys". This was to clear out any dross that might have found its way into the secure-boot mechanism and enable me to boot in Other mode - i.e. not a Microsoft secure boot. As Mick says, you need to install a kernel image in the boot partition (which must be FAT32). There are several ways to do this; I use bootctl from sys-boot/systemd-boot (don't worry - it doesn't depend on having the rest of systemd around it). It allows a choice of system to boot, without the gymnastics needed by GRUB-2, but you have to maintain the different images' config files manually. Let me know if I can' help with bootctl. Good luck! * An advantage of buying a newfangled system ready built. -- Regards Peter
