We have started getting in the new Latitude 5490 and 5590 laptops, noticed that they now only allow legacy external devices. My image templates kick off fine but when they reboot I get 'No bootable devices found'!
I have enabled 'Always boot UEFI devices' in the preboot settings, injected the dell drivers into the boot.wim and boot_x64.wim, redeployed PXE servers and still nothing.
Created a brand new template, used variations of templates that work with all previous. I have tried various different BIOS settings, RAID on, AHCI, secure boot off, nothing! What have I missed!?
I'm in a sticky situation, new starters etc piling up...... Help appreciated!
