Hi,

I'm actually deploying AiO (Optiplex 5250) computers with a golden image and trying to inject the corresponding driver package from the dell download page. Unfortunately sometimes it works, sometimes not. It says something like:

"5250 AIO-WIN10-A01-GCCHR.CAB" not valid for the selected model: 5250

WIN10

x64

5250"

I have no clue, why this is happening sometimes. Any relations to UEFi or legacy boot?
