      Here's an example of my Grub setting using UEFI on Fedora

      sudo cat /boot/efi/EFI/fedora/grubenv
      

      There we go.. grubenv is missing on my laptop.

        That can also be missing if you are not using UEFI. In fact, there shouldn't be nothing in /boot/efi/EFI/fedora/ if you using BIOS instead of UEFI.

        sudo find /boot/ -name grub.cfg will output one of the following:

        BIOS
        /boot/grub2/grub.cfg

        UEFI
        /boot/efi/EFI/fedora/grub.cfg

          UEFI
          /boot/efi/EFI/fedora/grub.cfg

          It is (was) UEFI for certain. BIOS config is set to UEFI boot.

            Remove grubenv, that's a nice update feature...

              On UEFI system, /boot/grub2/grubenv is a symbolic link to /boot/efi/EFI/fedora/grubenv. Maybe an update to grub screwed up something.

                I don't even if know if this will fix grub or not. But here you go.

                Create a new empty grubenv file in /boot/efi/EFI/fedora/grubenv.

                sudo grub2-editenv /boot/efi/EFI/fedora/grubenv create
                

                I noticed on my system, there is a symbolic of /boot/efi/EFI/fedora/grubenv in /boot/grub2/
                74e0d7c8-c3eb-40ce-a0ec-0bd242206235-image.png

                sudo ln -sf /boot/efi/EFI/fedora/grubenv /boot/grub2/grubenv
                

                Rebuild GRUB

                sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
                

                Rebuild initramfs images

                sudo dracut --force --regenerate-all
                

                And then reboot.

                  The updates show that grub had changes. Shit happens with all OS.

                    And then reboot.

                    Actually, the /boot/efi/ folder was completely empty. No sub-folders or anything.
                    I made EFI/fedora in there and then the commands ran.

                    But no change in behavior

                      @JaredBusch got a backup that happened to grab /boot...?

                      Or maybe copy what's needed from a working system?

                        No backup since the data is sync'd.

                        Mostly I'm trying to figure out how to resolve without a reinstall if possible for knowledge sake. Not to save my system.

                            Had to be, as it was working. I shutdown to go home. Then it wasn't working.

                                Unless someone has any more ideas, I'm also out of ideas and I will have to reinstall since I will need my laptop on Wednesday and Thursday.

                                  Kernel 5.3.12-300 is current.
                                  But both previous kernels fail also.
                                  5.3.11-300
                                  5.3.8-300

                                  So this suggests that a library or something has failed, not the kernel. That's going to be a huge pain.

                                    Right sounds like the grub update borked itself.

                                      Can't provide any input but it's interesting to read the problems that shows up every time there is a new Fedora release out. Your customers are a forgiving bunch for sure.

                                      That said, it's great for the open source community to have lots of people running the latest and greatest. 👍

                                      I've been on Fedora about 2 years on my laptop now and I know exactly what you're talking about.

                                      No new release issues on any Fedora system that I use, either. Been flawless and we use it across laptops, desktops, and servers.

                                        I did have a Fedora 31 laptop (different model Dell than mine) spun up and logged in two weeks ago. I have ran updates on that one and rebooted. it is running fine.

                                        Yeah, my Dell with F31 hasn't had an issue yet and I keep it updated.

                                            So this suggests that a library or something has failed, not the kernel. That's going to be a huge pain.

                                            Right sounds like the grub update borked itself.

                                            That's definitely my guess.
