Summary of this discussion as of 2024-12-21

-
I learned that I need to configure the PC Startup ( I call it BIOS) to allow insecure UEFI boot.
-
With that configuration I repeated the Manjaro installation from bootable stick hoping that the (Calamaris) installer would establish a system, where after power-on the GRUB boot manager shows the choice between Manjaro and Windows.
-
Our further discussion circles around the question why the GRUB menu does not appear after power-on.
3.a There are indicators that support the assumption that most likely Manjaro has been installed in UEFI boot mode:
-
see the photos of the Startup screen
-
see the output of the command:
dmesg | grep -i "EFI v" -
the fact that it is impossible boot the PC in legacy mode; I can only
boot in UEFI mode, but then Windows starts -
the fact that Manjaro can be started at all – even if only via Windows Recovery.
3.b There are indicators that support the assumption that most likely Manjaro has been installed in legacy boot mode.
- the observation that the GRUB menu does not appear when I boot the PC in UEFI mode.
3c. I do not understand what the results of the inxi command indicate.
I would not dare to repeat the Windows installation. The PC was bought with Windows 10 pre-installed; I have no expertise with Windows installation.
I would have repeated the Manjaro installation process from the beginning rather than conduct this discussion, but that would have yielded the same result, wouldn’t it? Therefore I believe it is necessary to find the cause of my problem.
Thanx for your continuous help!
