Hi everyone,

I have a XPS 13 and I've been trying to update the BIOS. The Dell update programme in Windows doesn't work (restarts and boots again to Windows without attempting to flash the BIOS). I then downloaded manually the BIOS update (XPS_9370_1.21.0.exe) and put it on a flash disk. I get to the boot menu and can select the "BIOS flash update" menu. I can locate and load the file, it's recognized properly. I then click on "begin flash update" as indicated on this site: https://www.dell.com/support/kbdoc/en-us/000128928/flashing-the-bios-from-the-f12-one-time-boot-menu and click "yes" when prompted "would you like to proceed".

Then the computer restarts and boots onto Windows directly, seemingly skipping the flash update. 

Is there something configured wrong on my BIOS that somehow makes it skip the flash update sequence?

NB: I'm on Windows 11 home (no BitLocker, etc.).

Thanks in advance,

Julien
