Thanks, Philip. Toward the second part, you don't really need a USB memory drive if you are using UEFI boot. Just copy the exe file to /boot/efi/ and hit F12 at the POST. You can select "Flash from File" (or something like that) and select the hard drive (your system drive) and you will see the exe there. Select that exe file and click on "Submit." Then "Update BIOS".
@@shanobuo the problem is that my directory goes beyond: I've got /boot/efi/EFI and then there are 3 additional folders (/Boot, /OEM, /ubuntu) and I don't know where to paste the exe file
UUuuuu excellent many, many thanks, your video helped me to repair the bios of a Latitude E5440 of my work, excellent and fast with the great GNU-Linux Ubuntu 20.10
The USB route worked perfectly for me on my Inspiron 7375, updating the BIOS from ~1.3(forgot the exact version blah) to 1.9.0 - currently running Ubuntu 22.04 LTS.
I followed all the steps but when I get to the boot screen I press f12 but nothing happens, this only happens when the USB is in the computer. Any idea what the problem is?
Thanks, very clear! Unfortunately I have a pre-2015 Dell that doesn't have the "BIOS Flash Update" F12 menu, and also Ubuntu installed on MBR vs GPT. Also fwupdmgr get-updates shows no available updates, so guess I'll have to live with the older BIOS from 2018, but the latest is only 2019, so oh well lol. Oh, and Dell's update advice using the BIOS exe from a FreeDOS boot unfortunately no longer seems to work either. Hopefully most of your viewers will have newer machines and I'm sure this video will do the trick!
@@philipyip1988 Thanks for your reply! Once again very clear instructions! I tried the the method using Rufus on a Windows 10 machine, and when I booted the USB on my Ubuntu machine and ran BIOS_A12.EXE, I got the same error "This program cannot be run in DOS mode." So I think the particular BIOS update I am trying to apply (A12 BIOS for an Inspiron 15R 5537) must be compiled to run only under Windows and not DOS. This is the exact same error I got when I created a FreeDOS boot USB from an image I downloaded directly from the FreeDOS web site using Ubuntu's Startup Disk Creator. In both cases I never got to the DOS text "BIOS Update Utility" screen in your video, but do remember seeing these long ago. I guess Dell has changed their BIOS update tooling on some models.
@@WalterWittel The Drivers and Downloads Page states "This file format consists of a BIOS executable file. The Universal (Windows/MS DOS) format can be used to install from any Windows or MS DOS environment." however if you are getting that error message it is unlikely that you can run the BIOS Update in a FreeDOS Environment. Sometimes the Inspiron Systems are a lot more restrictive than the Business Models. The .exe though appears to be a package that contains other .exe files. You might be able to extract it and copy the contents of the extracted folder to the FreeDOS Bootable USB and then launch the InsydeFlash.exe via FreeDOS, but you may just end up with the same error message.
@@WalterWittel I know it's been a while, but have you managed to update your bios? I have a pretty old dell laptop, and i want to update the bios on it.
@@feeloex No. AFAIK if you don't see a "BIOS Flash Update" F12 menu you are out of luck. Check for that and if you have this menu then this video probably will work for you. Results will vary based on the age and model of your computer. I've elected to just continue running the last installed BIOS on that machine until it dies and gets a proper e-waste burial. Perhaps there is an open source BIOS that would work, but I suspect it would have to be tweaked / recompiled for specific motherboards. I haven't looked into this.
As far as I can tell it can't be done with the Linux Vendor Firmware Service unless the OEMs support BIOS downgrades with the LVFS (in most cases they don't). In some cases the USB flash drive method can be used to downgrade the UEFI BIOS.

I used this tutorial to update my Alienware 13r3 BIOS with Manjaro using the USB flash drive. Apparently works. Thanks for the video.

Hi! Where did you exactly paste the exe file? I've got /boot/efi/EFI/ and then three other folders (/Boot, /OEM, /ubuntu). Thanks!
Here is an example:
$ sudo ls -l /boot/efi/OptiPlex_7050_1.21.0.exe'
-rwx------ 1 root root 22299176 Aug 9 07:17 /boot/efi/OptiPlex_7050_1.21.0.exe

Very helpful, I didn't know about the firmware manager. Many thanks
Worked perfectly fine. Helped my after market battery to be recognized by the system.

I have a FreeDOS BIOS Update example here with both Rufus and UNetBootn:

i recommend
I don't have a BIOS Flash Update. What then?
Very good
I've watched a couple of your videos and my god have proven useful.
Do you know how to downgrade bios?

I keep getting invalid file
