I have Framework 13 (AMD Ryzen AI 9 HX 370), the pre built one. I had zero issues with it, I am happy with the purchace. I am using NixOS (nixos-unstable channel). Lately I noticed occasional screen flickering only on the top of the screen, I switched kernels from 7.1.7 to 6.18.x, did not help, then I updated the BIOS in hope that would fix something, so I ran:
fwupdmgr refresh --force
fwupdmgr get-updates
fwupdmgr update
All went without issues, even the BIOS update seem to went well… except that issues got bigger.
I can not boot anything anymore, nor the hard drive nor the USB drive, it says “[drive name] boot failure”, and if press Ok, it just shows a qrcode for No Boot Device Found
Once you gave me the correct way (my way was just press F2 on the qrcode page, it never occur to me to press F2 right after turning it on) to open BIOS and the idea on that secure boot keys might be missing, I went to update that, and find a way on Lanzaboote page:
