Hi guys, l posted this over in the Dell Forum as well.

Am using SCCM (Current Branch) to deploy our Windows 10 (1803) corporate image. As part of the build process we upgrade the BIOS.

With Latitude 7390's & 7490's we would use "flash64w.exe /b=<name of bios file exe> /s", during the WinPE stage; worked perfectly.

With the Latitude 7200 2-in-1, the bios update process fails to run. If l open up a command prompt in WinPE and run manually, the flash64w process stops as soon as it is spawned.

I have tried a variety of switches as well as the logging switch, but nothing gets logged to the log file. Also turned off virtualisation in the BIOS.

The BIOS update runs within Windows 10 ok, just not in WinPE.

I suspect this range of laptops might require an updated flash64w.exe??? I've got a 7300 and a 7400 that l can try as well.
