EDIT - UPDATE: Booting live Windows11 USB has worked and BIOS has been updated (but holy cow, Linux live USB feels like it’s running on SSD while Windows live USB feels like it’s running from floppy disk)

Hi, I have a Yoga Slim 6 14APU8 - Type 82X3 laptop with Fedora Workstation 41 and I’ve tried to go and update my BIOS but unfortunately they only offer the .exe file to do it from within Windows. I don’t want to install Windows just to update my BIOS. I honestly though it will be a matter of few minutes by me just copying the BIOS file on a USB drive and then installing it directly from within BIOS as usual on other devices…

I’ve tried the sudo fwupdmgr update command but it just says that there is nothing that can be updated.

My current BIOS version is M4CN30WW and the new one is M4CN36WW.

I’ve tried searching for how to do this and I’ve found multiple guides using geteltorito but they all say to download the .iso and not the .exe version of the BIOS file but I can’t find the .iso version anywhere on their website, or am I just blind or is there some other way to do this?

    UEFI by default runs exe

    As far as I know, that’s not the case. Maybe some UEFI implementations by some vendors can extract the UEFI firmware that’s embedded in the exe file. But, UEFI doesn’t run exe files.

      OK I was wrong it’s not default EXE it is the only option https://wiki.osdev.org/UEFI

      UEFI executables are regular PE32 / PE32+ (Windows x32 / x64) images, with a specific subsystem. Every UEFI application is basically a windows EXE (or DLL) without symbol tables.
