@Tom-Elliott Yeah, the args passed on the image in my original post shows /dev/nvme0n1, which I believe is the SSD.
I did try changing to the HDD by going to the FOG portal and changing the primary hard disk field for the specific host but it resulted in the same error.
But also, looking at the successful reimage of another machine (that is already working), it seems that the correct disk to use is the SSD but the 5th partition? As can be seen by the dev label in the image below? I’m not sure if I have to start looking at the partitions or something else entirely.
I could be misunderstanding or maybe I didn’t change to the HDD properly.
