I also have an Asus motherboard, but for Intel hardware. |

In your BIOS secure-boot page, do you have a section called Key Management? |
| 28 |
When I was working on getting my machine to boot, a year ago, I was advised* |
| 29 |
to hit the item "Load default keys". This was to clear out any dross that |
| 30 |
might have found its way into the secure-boot mechanism and enable me to |
| 31 |
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 |
| 34 |
(which must be FAT32). There are several ways to do this; I use bootctl from |
| 35 |
sys-boot/systemd-boot (don't worry - it doesn't depend on having the rest of |
| 36 |
systemd around it). It allows a choice of system to boot, without the |
| 37 |
gymnastics needed by GRUB-2, but you have to maintain the different images' |
| 38 |
config files manually. |
| 39 |

Let me know if I can' help with bootctl. Good luck! |
