Why is BIOS update failing? | DELL Technologies
February 15, 2025 - The command line switches in this post produced errors, which led me to try /? and that gave me /s /r as switches with which to run the bios executable from within Windows (I booted into Win10 for this). So I ran the bios exe with /s /r /l c:\log.txt, the machine rebooted and it went through the bios update process. Re-installed my previosuly upgraded Win 11 disk and now Win 11 works.

Trouble updating BIOS on Dell computer Solved - Windows 10 Forums
February 11, 2022 - I did some more digging and found that the flash drive had to be set up as a bootable flash drive, which mine was NOT. I first clicked on the .exe file around 9 AM this morning and its 7 PM now but apparently the whole process should only take a few minutes. I've received no error messages but when I try to launch the .exe again, it tells me its already running. It's just not DOING anything visible and it's not showing any error messages. I'm wondering if I can kill the BIOS update process, recreate the flash drive so it is bootable, put the .exe file on it, and then try the BIOS update again WITHOUT destroying the computer in the process.

BIOS update always fails | DELL Technologies
November 1, 2023 - I'd recommend you stop trying to update BIOS using Dell Update/SupportAssist. It's always safer and easier to update BIOS entirely outside of Windows.
