Can't access NVME drive when booting from USB or SATA (Librem Mini)

Thanks for the reply. Unfortunately, that made no change. I:

  • removed the NVME drive
  • reached the ISO’s GRUB screen
  • reinserted the NVME drive
  • booted into ISO OS
  • ran sudo fdisk -l (only showed USB and SATA devices)
  • ran sudo sh -c "echo 1 > /sys/bus/pci/rescan"
  • ran sudo fdisk -l (still only showed USB and SATA devices)
