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?
As someone mentioned, there is a chance that it is and executable wrapper for like a zip archive that contains the flash ROM. You should try to extract it using something like File Roller. If you can extract the ROM file, he can typically flash it manually from the UEFI or BIOS menu.
File Roller worked for extracting but the BIOS file seems to be in a .fd format and it does not look like I can do anything with it without further modifications. I'm still downloading ISO for the live Windows USB.
The
fdfile is likely the bios image. You can probably just stick it on a FAT usb drive or even just the EFI partition if you have one.You can probably flash that from the bios itself.
The bios might expect a different file extension, so just rename it
