1. Create Live Stick with Manjaro

• Download: https://manjaro.org/downloads/official/gnome/
• Create bootstick: https://manjaro.org/support/firststeps/#making-a-live-system

2. Change UEFI Settings on your broken system: Boot > Secure Boot > Other OS (You can also disable UEFI, but make sure to re-enable it after you are done here!!)
3. Boot broken system with the live-system
4. Open a terminal

Option A (your main hdd is encrypted)

• Decrypt and mount it
• Mount your decrypted hdd to /mnt

$ mount /dev/dm-x /mnt

Option B (no encryption)

$ sudo manjaro-chroot -a

• If you get an error "Can't find mount point 0!", your hdd might be encrypted? Try Option A

5. Run a package database update

$ pacman -Syy

6. Install package updates

$ pacman -Syu

• If you face any errors, cause you enabled timeshift backups. Run following command instead

$ SKIP_AUTOSNAP= pacman -Syu

7. Exit and reboot

8. Turn on your UEFI if you disabled it, or change it back to its original setting, to enable a proper check during startup!

Well, Manjaro nuked itself while normal update, no power outages, just normal reboot after update (which Manjaro has asked for).
It's hard to trust this OS any more.
