Bios/UEFI changed

Hi. I installed manjaro xcfe latest version several days ago(maybe more than a week ago). It was working good, but I just encounter weird thing: computer was unable to start up, actually screen was black. After several unsuccessful trials to reboot, massage appeard that “safe boot failed”. I realized that safe boot was enabled in bios. I desabled it and then faced other error that you can see in picture below. It appeared that disk mode was changed and I changed it back to AHCI. I did not touch anything in bios myself. Could anyone please explain how system managed to change bios? What happened?!


Are you asking what might have triggered the changes in the BIOS?

Is your original issue resolved, however? Can you now boot into Manjaro normally again?

I don’t think Linux ever touches the BIOS/UEFI… Maybe it’s an issue with your BIOS/UEFI itself, which might be fixed if there is an update?

Could be the goblins from Redmond, WA.

Yes, I am interested what could possible trigger such changes? After I desabled safe boot and changed disk mode I was able to boot manjaro.

Thanks for suggestions.

By safe boot - do you mean Secure Boot?

I am sure that Windows - like Linux is capable of updating the updating the systems firmware - albeit on LInux this is never done automagically but only on demand.

It could be a simple reset of the firmware to defaults - which on many systems include - to conform to Microsoft requirements - enabling Secure Boot. Some modern systems defaults the device controller to a special setup which moved system files to a faster section of the disk.

While it is technically possible and I suspect Windows is capable of - on select systems - to modify firmware settings.

If this happens it is usually in connection with a Windows update which requires restart.

Although I am not sure if it will work - you could password protect the firmware - place a sticker on the back of the computer with the passphrase - after all this is only to verify if Windows is trying to change your settings.
