@jmason said in Dell 7730 precision laptop deploy GPT error message:
Ubuntu showed the behavior on the 3rd with lsblk and 5th reboot with dmesg, while reboot 7 was different than all previous, I’ll move on to the other 2 ISOs next.
Since this issue is happening with a commercial versions of linux… I wonder if there is any value in calling Dell tech support? This could be the linux kernel doing this, or it could be the uefi firmware. I think you have enough evidence to say its either the hardware, uefi, or the linux kernel doing it. Your ubuntu test doesn’t use the latest kernel, but FOG does so you have a range of kernels where this problem exists.
