@ntrumpff17 The problem is that if you are using the intel hardware assisted software raid (aka intel fake raid) with the hardware controller in (Dell’s term) Raid-On mode and your computer is UEFI based, the linux kernel can’t see the drives behind this intel controller in raid mode.
Now I do have to say I have not tried with the 6.x generation of linux kernels, but the older versions could not see the drives. So the trifecta of the issue is
Intel Raid enabled + uefi firmware + linux kernel == no drive access. If you change one of the variables fog can image the computer.
The reason historically is that Intel has not released the driver interface details so that a linux driver could be built.
