Dell Optiplex 390. No boot sequence option
My computer is failing to boot.
I tried to reset boot settings but the problem still persist.
I tried to change boot sequence but the boot sequence is not showing any option in the catalogue box. What's the matter?
No Events found!

you need to connect a UEFI bootable media such as a USB to pc, then manually add the boot option in the 390 bios which was a primitive version similar to 790.

@redxps630
How should I do it? Should I download a file for bios update or what ? Your answer is incomplete
