      I’ve installed FOG 1.4.4 on ubuntu 16.04, imaged almost two dozen boxes around the house, and loving it. The UEFI boxes are proving a bit of a pain.

      This is an NVMe drive with SATA mode set to RAID for Intel’s RST. Reading I’ve done on this box and NVMe drives says you must keep RAID mode to boot. I’ve seen a dozen posts similar to this dealing with raid, and my head is swimming quite honestly. This isn’t an array. It’s simply RAID mode. Is mdraid or mdadm appropriate?

      Basic vanilla capture gave
      “Cannot find disk”

      I added …
      Host Kernel Arguments: mdraid=true & Host Primary Disk: /dev/md126
      which gave me “failed to read back partition (runPartprobe)”

        Lets make sure we understand something here.

        Do you, are you using intel’s “fake-raid” on this computer or do you have a single disk and raid-on is enabled in the bios.

        I can tell you with Dell computers in UEFI mode, and the disk adapter set to raid-on (factory default) with a single disk installed, linux will not boot in this configuration. You MUST change the disk mode to AHCI mode to get the device to boot in linux (FOS uses linux to move image files). Once the image file has been deployed you can switch raid-on back on.

        I understand that screen shot is not a Dell systems, but the same rules apply.

        Now if you ARE using Intel’s hardware assisted software raid, then you have started down the right path. Once we know what you have we can give you better debugging directions.

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

          Thanks for the quick response.

          I am running one NVMe “disk.” This is a SATA mode setting in the “BIOS.”

          I switched to AHCI once, and no boot options were accepted. No access to bios was allowed. It was a boot loop until a bios setting “3 failed boots and restore last good settings” broke the loop and gave bios access back. After that, I was really hoping there was another route.

          I’m pretty sure all the screenies came from this Dell XPS 8920 box I’m sitting at. What would make you think otherwise?

            Sorry that just shows my ignorance of the Dell consumer bios screens. I use the Dell business computers in my office and the bios is totally different.

            OK what I want you to do this is this.

            1. Configure the firmware to what ever you consider as default.
            2. Manually register this computer if its not currently registered.
            3. Schedule a image capture or deploy I don’t care, but before you hit the submit button to schedule the task, click the checkbox for debug.
            4. PXE boot the target computer, this should automatically start the debug capture/deploy.
            5. After a few enter key presses on the target computer’s console it should drop you to a linux command prompt (on the target computer).
            6. Key in the following command
              lsblk
              blkid
            7. Post the results here. The lsblk will post what the FOS engine is seeing for block devices on the system.

              Back at it. One of the other hats I wear got in the way.

              I’m on FOG 1.5.4 \ kernel 4.18.3

              As requested…

              Any hope of getting this NVMe to show up?

              also … on pxe boot this comes up … significant?

                @geardog Ok your NVMe disk is not seen by our FOS linux system. Can you run another debug task and run lspci -nn - post picture here.

                Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

                  lspci -nn showed the drive to be in raid mode

                  using a tutorial on bcdedit via cmd for safemode boot I was able to change the setting without reinstalling windows

                  now the machine is imaged

                  resolved and thankyou

                  coming back to this with a fresh mind and some new info helped
