Imaging Latitude 7290 (what is legacy external and how do I avoid it)
I am testing the Latitude 7290. I usually switch from UEFI to legacy. Now legacy is external only. I am at a loss. I finally got it to image through lots of trial and error but now it only tries to boot to the network and not to the hard drive. When I go into BIOS I have 3 choices. UEFI no secure UEFI secure and Legacy External. None of which show the hard drive as a bootable device. Thoughts and ideas are welcome. My supervisor believes this to be a driver issue. I think it's a BIOS issue. Help!
Also how long does it usually take for the drivers of new models to show up in the Driver feed?
