Dell Inspiron 16 5645 Ubuntu Bios Update
Hall first, I have installed Ubuntu on my laptop. It runs without any problems. I only have one problem: I wanted to update my bios. I took a USB stick and formatted it in Fat, then I copied the Bios file to the USB stick. Then I restarted the laptop and pressed F12, then this picture came up. https://postimg.cc/1VXgg9JQ , then this picture https://postimg.cc/kDY60bgX , then this picture https://postimg.cc/GHB8dm4P , then I had to press Y for it to run. But as soon as I pressed Y I ended up here again https://postimg.cc/1VXgg9JQ . I tried that again but again the same thing, it just doesn't work.
I pressed N once and the laptop restarted.
The problem is I can't update my bios. No matter what I do.

Hi
Installation
1. Copy the downloaded file to a USB drive. You do not need a bootable USB drive.
2. Insert the USB drive into any USB port.
3. Power on the system.
4. At the DELL logo screen, press F12 to access the one-time boot menu.
5. Select BIOS Flash Update in the Other Options section.
6. Click the ... button to browse the USB drive to locate the downloaded file.
7. Select the file and click OK.
8. Verify the existing system BIOS information and the BIOS update information.
9. Click Begin Flash Update.
10. Review the Warning message and click Yes to proceed with the update.
The system restarts and displays a Flash Progress bar at the Dell logo screen. The system restarts again when the Flash update is complete.
So you have gone thru the correct procedure.
Two thoughts, update the BIOS to version 1.9 first?
Have you tried with fTPM ON?
Also there is a BIOS .rcv file available, perhaps get a copy of that as a backup?

What do you mean by fTPM on? Is it on for me? Do I have to switch it off?
I have tried the other functions, but it does not work.

Hi
In your case I suggest you leave the fTPM as it is.
"Resetting fTPM erases all TPM-stored keys.
If you use BitLocker or similar encryption, you must have your recovery key to regain access to your system.
If you do NOT use encryption, resetting fTPM is typically safe and resolves compatibility or corruption issues."

Ok, it doesn't help. I wrote to the Dell support chat. They said I should reinstall WIndows to update the bios, the Ubuntu bios update is not supported.

Hi
Well I read it and understand it differently.....
""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. ""
AND of course there is this....
How to Update the Dell BIOS in the Ubuntu or Linux Environment
https://www.dell.com/support/kbdoc/en-uk/000131486/update-the-dell-bios-in-a-linux-or-ubuntu-environment
The Inspiron 16 5640 is listed, but the 5645 is not.
None of which says, or means, I believe, that W11has to be installed.
It should update from a troubleshooting / command prompt in a W11 install environment where you choose to REPAIR, not Install.
There is the OPTION to use FREEDOS according to DELL.
############
But I bow to the superior chatbot knowledge, rather than the DELL support pages.
