now, it seems not to contain any trace of problems, which I see on power
on instead. Might they be not recorded, or recorded elsewhere ?
as for the article : I just have both FASTBOOT and SECUREBOOT disabled,
but I am not sure enabling EFI feature (I cannot remember if it is just
enable, actually), or simply changing its state, would be safe.
I dread it would be no longer compatible with other options that now work,
more or less. I fear to get a system non bootable (I have never modified
this setting after installation).
And here I do not even have a dual boot like in old machine.
Is it safe to alter the EFI / LEGACY option after the installation ?
