Vostro 3525 BIOS Flash Update error 'Invalid file'

Question

Hello. I try to update BIOS on my Vostro 3525 (with Ubuntu 20.04 TLS OS, current BIOS version on laptop 1.1.0), but got error 'Invalid File' when select file 'Inspiron_3525_1.2.0.exe' in BIOS Flash Update. So 'Begin Flash Upgrade' button stay unavailable.

I used this instruction: article 000131486 . I follow the 'Updating the BIOS on supported UEFI systems (2015 onwards)' (legacy boot unavailable on my laptop) and stuck with update at step 3.3.

Any ideas or tips about this problem? error error

Update: interesting observation, not sure if it matters... No 1.1.0 version installed on laptop in list available versions for download on site

Did you get any luck? I'm stuck with the same issue. Dell support is not being helpful.

Unfortunately no. The problem is still the same

Just to check, did you have any troubles with grub after windows install?

I found tricky way today: install as second OS Windows 10 (with the initial settings, I did not even configure the network) and execute from USB all BIOS updates (1.2.0, 1.3.0, etc) from Windows. Now I have 1.7.0 version on my laptop.

This is probably a bit complicated for some users and doesn't answer my first question, but the BIOS has been updated.

Bruh, I had a feeling it would work like that, but I didn't have the energy to try it.

I don't get why Dell posts guides to update BIOS in a linux environment when it doesn't even work lol.

I guess I'll install w10 for a couple of hours.

Thanks man!

I used this article  and as says there grub don't see windows presence. So you can choose booting Windows or Ubuntu via F12 or update grub for dual boot: sudo update-grub
