Trying to deploy image to Dell Latitude 5490. I usually switch from UEFI to legacy run my task sequence without any issues. Now legacy is external only. I did through lots of trial and it only tries to boot to the USB media and not to the hard drive. When I go into BIOS I have 2 options. UEFI and Legacy External. None of which show the hard drive as a bootable device when I select legacy mode. Your help is greatly appreciated
