I recently procured a Dell Latitude 5510 to run Ghost. Initially, the installer wouldn't detect the NVMe HD, but I found a comment on a post on the FreeBSD forum commenting that many Dell laptops ship out with RAID enabled. I dug through the bios to find that setting, and sure enough, it was set to RAID. I unchecked that, selected AHCP, saved the change, and the installation then went forward without a hitch.
