@mrzo For the record - my organization has had a whole lot of problems with the Lenovo M72e. And when I say problems - they are (currently) absolutely not working with FOG Trunk.
The strange thing is - the 30 or so that we tried every method in the book with - one of them always succeeded while every single other one always failed… we have sat down and compared Firmware settings, we’ve restored firmware defaults… we can’t figure it out, it’s a mystery at the moment. We are currently using WDS and/or Norton Ghost for that particular lab.
We have no M83 models in our environment - but I wanted to just shed a little light on my experience with Lenovo. I think some of their other models don’t quite like San-Boot style HDD exits either… Lenovo is… a PITA.
AHCI is the preferred operating mode, it’s a best-case scenario that you have a mechanical drive.
You say that the system is configured to boot via UEFI ? What boot file are you using? Have you tried others?
