No boot to USB option in a Dell OptiPlex 3080 with BIOS 1.3.2, nvme ssd
We are trying to boot to a usb which I created in Rufus and tried both GPT (non CSM) and MBR (CSM). I tried changing all related options and disabled/reenable secureboot. I also tried creating a Linux and WinPE bootable USB within backupper.
The only options are Windows Boot Manager, Lan1 and Lan2.. I know legacy boot is gone with this gen processor so that's not there.
I did read somewhere where if you wanted to boot to a CD/DVD, you need to manually add it, unfortunately I didn't see the "cd" option in the file system list.
I tried re-flashing 1.3.2 and defaulting the settings. Any help is appreciated.
another used reported the following works in another ##8# Dell that has uefi class 3 (post sunset of legacy bios).
First and foremost prepare uefi bootable usb stick and plug it in pc before powering up, otherwise it would not show up in bios.
