      FOG 1.5.0

      Hello,
      i’ve got again the same problem with uefi computer (Dell).
      Before it was possible to use legacy boot with internal device, with new computer Dell, it’s impossible now to use internal device.
      Then i have to use UEFI settings.

      The computer boot PXE correctly and i’ve got the PXE menu.
      Everything works fine except “Boot from hard disk”.
      When i choose “Boot from hard disk”, i’ve got the “chainloading failed…” error message.

      For this host, i tryed :
      Exit : no success
      Sanboot : no success
      REFIND_EFI : no success

      Have you got a solution for that ?

      Thanks for your help

        For each host as well as on a global level, there are exit modes for both bios and uefi based systems. By default your exit mode for bios should be sanboot, the default exit mode uefi is refind. The chain loading failure is a bit confusing since that means iPXE could not call the exit mode.

        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!

          Actually on the global level :
          exit mode for bios is sanboot
          exit mode uefi is exit.

          On the host level configuration, i tryed :
          Exit : “chainloading failed…” error message.
          Sanboot : loop on the main menu
          REFIND_EFI : It seems that the partitions choosen is the repair partition

          What kind of informations do you need to help me ?

          Thanks for your answers

            OK so refind IS NOT giving you the chain loading error, but just selecting the wrong partition. Is that correct?

                  @plegrand Well it IS a different issue. Basically, a chain loading error is roughly equivalent to a blue screen in windows. Where refind not identifying the proper boot partition is a problem. The end result is that it doesn’t boot, but for different reasons.

                  If you change the default boot order in the firmware to the hard drive first does it boot as expected?

                      @plegrand Ok, so we need to understand why refind is incorrectly selecting the recovery partition.

                      From a windows computer, can you give us a screen shot of the disk partition layout? You can do this from the Computer Management-> Disk Management plugin. Is your disk layout unique or just what ever windows picks when you install it?

                              Do you think i should upgrade FOG to the latest version ?
                              I’m using fog 1.5.0
                              Is there some risks to upgrade to 1.5.4 ?
                              Thanks

                                  Then i made a try by modify the “/var/www/fog/service/ipxe/refind.conf” file

                                  # scanfor internal,hdbios
                                  

                                  Now it works :
                                  After the PXE boot menu
                                  It display refind logo

                                  • Why it display 3 times the DELL logo ?

                                    In fact here is the situation.
                                    The only problem i have is with uefi local boot.
                                    i tried Exit Sanboot REFIND_EFI without success.
                                    Is there a way to solve that?

                                      Wow sorry I did not see this until now. Let me try to catch up.

                                      1. Yes you should always be on the latest release. Currently its 1.5.4, the developers are working on some fixes to 1.5.4 with the 1.5.5 release but upgrade to 1.5.4 and then I can help you with the fixes to 1.5.4.

                                      2. If you disable options in the refind.conf file it will take what ever the defaults are built into the program. I’m trying to remember, I believe there was an issue with refind 0.11.2 where downgrading refind to 0.11.0 solve the user’s issue, but I can’t seem to remember what the problem was that this is a fix for.

                                      3. Sometimes the uefi firmware needs a little settling time before refind scans for hardware. There is an option in refind.conf to have refind pause for a bit then attempt to detect hardware.

                                      4. For uefi systems your only options are refind and grub the rest are mainly for bios mode computers.

                                      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!

                                          To fix, you must just download to FOS kernel 4.15.2. The developers found what was causing the issue in a third party application. They are currently working with that third party application to resolve the issue. That fix will be rolled out with FOG 1.5.5 and the linux kernel 4.18.x.

                                          There also is an out of memory condition that is fixed by adding a line to a php-fpm config file. With these two fixes FOG 1.5.4 works pretty well. There is still an issue with multicasting with 1.5.4 that has been fixed for 1.5.5. I believe the developers are trying to track down a FOG image replicator issue at the moment.

                                          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!
