How do you update UEFI/BIOS with LMDE 6 installed?

Mine seems to be up to date at the moment (did a most recent update just after the 11th June as there was some vulnerability, while still having Win11 in the system, but for future reference if I needed to update UEFI with LMDE. How do you do it? Most of the advice online is for Ubuntu.

I have checked the dell manufacturer and for some reason my model Latitude 3520 isn't included among those that could be updated directly via LFVS. Above these was 3400 series, 3520 not present.

I did download the FreeDOS and put the .img file as well as the updating .exe file from Dell onto my Ventoy usb, being told it should update BIOS that way, but I haven't used it yet as my BIOS is up to date (I use UEFI and BIOS interchangeably). Unlike for other folks who demonstrated FreeDOS installation in their VM, I didn't get the .iso file in the package, there was the .img instead. My Ventoy usb should handle it well I guess.
Is it this way? Via FreeDOS?

I came to this topic when I couldn't launch Win11 from the ssd card parked in an enclosure. I simply swapped the NvME SSDs, installed Linux on the new one and the previous one got a new home in this enclosure for such memory device. It didn't boot from there. The bot suggested updating BIOS, but that one is up to date. What is different between the two SSDs, one implanted into the laptop and the other one as an external source? Is there any way around it not recognised by the system? Do I need to convert it into an iso file? Or how do people use this enclosure then? Something is lingering in the back of my head about mounting or something... new to it.

Here is the Win11 SSD in an enclosure that was previously running the laptop. The device with content is recognised and I can view content when I open it in Linux as a usb drive. So it clearly is communicating with the system.

Did you have the ext windows drive connected when you installed Linux? if not, your problem is likely to be you do not have a multi boot grub,

try connecting the ext drive, booting your Linux OS, open a terminal and run

sudo update-grub,

[you will be asked for your password]

and re-boot

then when you switch on again you should get the boot selection screen it will say [something like]

Mint LMDE
Mint advanced options
Windows XX
Windows advanced options
you then select which to boot by use of up/down arrow [or mouse] and enter, you will have about 10 seconds or it will boot to first option as default

Thanks, I have made a progress, but hit the wall, the same as I did this morning.
I now can see the two options, but when using the Windows one, I get this blue screen. I searched for its info earlier today, but didn't get any wiser.

These are the options I got after running the sudo command:

And the blue screen:

That was without the secure boot. But even after turning it on, I am facing the same issues.

Screen showing automatic repair, then diagnosing your pc (on black screen with dell logo on), ending with the BSOD again, after I rebooted again and chose the Win11 option.
 
I boot into LMDE without issues though.

Don't know whether this will be of any help:

Windows will always try to take back control of your machine , do not turn secure boot or quick-start back on or you will be back to square one
.
The boot selection screen is basically what expected to see,

the blue screen of death, I can't comment on as I haven't used windows for many years, but i certainly would not let it do any form of auto repair.

Keep fingers crossed, another member who has a duel boot may have seen the problem before.
 
Nobody updates BIOS on Linux?

In the meantime I am creating a live usb with Win11 and the direct booting after the grup update seems to work like a charm.

It depends on the motherboard/UEFI/BIOS.

But I have some Windows systems that I can't update the BIOS from Windows either, so it isn't just a Linux thing.

Typically I boot into the UEFI and do a USB drive update.

it is something most of us do not do, you can cause more problems, if the original BIOS/UEFI works, then why take the risk.
In over 40 years of playing with desktops and laptops [IBM OS/Various Dos/Wind/Macos/linux], I can count on my fingers how many times I have had to result to upgrading the BIOS [and still have some spare]

I see. I managed, last time, from the Dell website, it detected stuff and uploaded it almost by itself while running Windows11, I just pressed buttons and kept the device powered. I have a second hand laptop so I also flashed the TMP. There was some vulnerability discovered on BIOS so I updated it as advised.
