I had replaced Windows 10 with Linux Mint, and now I don't know how to update its BIOS.
I checked my current BIOS is not the latest,
so I downloaded the latest BIOS file from Lenovo official support website, but it is an exe file and I cannot use it as in Windows.
Even in current BIOS there is no BIOS update menu (like the EZ-Flash).
I tried using 'fwupd' as following:
but it says the signature is not valid.
I got stuck and cannot move on from here.
How can I update its BIOS on this Linux Mint?
I also referred to this website, but failed to find a solution: https://wiki.archlinux.org/index.php/Flashing_BIOS_from_Linux
