F27: Dell 5580: Cannot access M2 SSD drive on nvme0n1

On a Dell 5580 with a working windows installation I boot F27 from an USB stick in basic graphics mode. All well, I get a GUI and can start a terminal.

My plan is to make a raw copy of the /dev/nvme0n1 device to create an image to be used to clone other machines. This has worked well for a number of other Dell, HP and Lenove PC:s. However, I cannot see any /dev/nvme0n1 device. lsblk only lists /dev/sda (the USB stick) and some loopback devices.

I have testing all sorts of changes: F26 vs F27, UEFI vs BIOS boot, disabling/enabling firmware password... frustrating fact is that at one point I could access the M2 device. But at next boot it was gone. Testing other 5580 boxes gives the same result. FWIW, my gut feeling is that the BIOS plays tricks on me.

Any hint, out there?

PS: Yes, I recently asked almost the same question. Thought it was solved. But not. DS

I found your tutorial very helpful. I hope it would also work on my Dell laptop. spotify not responding

OK, seems that it's the firmware Boot Sequence setting which is the culprit. With this set to Legacy, the nvme devices are visible. This applies also if doing an UEFI boot (with this setting, a standard FEdora installation offers both a UEFI and a BIOS boot entry).
