Flashing Bios in Ubuntu

[p33p3rm1nt]

Hey guys,

I have a Thinkpad E540 and I need to update the Bios. I don't have Windows installed so I have to flash the bios in Linux. Lenovo offers either an .exe file or an .iso image for the Bios. I tried to do this using the following tutorial (https://ubuntuforums.org/showthread.php?t=2380411&p=13721659#post13721659) but it did not work. Since this is an old computer with a DVD drive I was just thinking to use that and not run in circles with USB formats, el torito and whatnot. However I can't find any specific resource online if there are any special things one must do with the .iso. Do I just simply burn it on a DVD as I would any other ISO and just boot from it? On the page, it says this image is meant for Windows OS-s, nowhere is Linux mentioned. Any step by step tutorial for this? Don't really want to turn my laptop into a pile of metal by messing up with the firmware.

Why do you want to flash your bios.

If you are not having any problems with you computer and not upgrading hardware not supported by current working bios I would suggest leaving the bios as it is.

I use old computers with original working bios and see no need to change it.

I would stick with a sure thing.

An .exe file is of course meant only to run on windows and if the site says the iso is meant to run only on windows, I would take their word for it. The link 'tutorial' you posted is broken so we have no idea what you are referring to.

I have problems with my computer. I don't just want to upgrade for fun. Technically I have over 7 newer bios versions available but I only need to go from 2.17 to 2.18. That update fixes my issues.

People update their Bios in Linux all the time. This is not something unseen, and virtually no hardware provider has Bios updates meant specifically for Linux users.

This is the tutorial I meant https://www.youtube.com/watch?v=WqDUCfU-e-A
