I used that trick to switch between “raid on” and “AHCI” during more than one year right now, and it worked well but…
Now we got NVMe SSDs in our new DELL computers, which need to be configured in “Raid ON” as “Sata Operation” to boot on Windows. Do you think that “GetHardDisk” error will be fixed in next versions ?
I think you have two different issues here. The first issue is the raid-on vs ahci mode. This is an age old issue between Intel, Linux, and uefi. With these three amigos working together linux can’t currently see any disks behind this configuration. If you change any of the three (really two) linux will see the disk. From what I understand the issue is related to intel not releasing the uefi raid drivers to the linux community.
The second issue may be new Dell hardware with these NVMe disks.What version of FOG are you using? What version of FOS Linux kernel do you have installed? What is the model number of the computer with this issue?
