        The contents of /etc/grub.d seem identical on all three systems I have here.

        1. My Desktop - have not tried to reboot
        2. My Laptop - does not boot
        3. Spare Laptop - reboots successfully.

          I'll have to check my laptop to compare kernels. Mine won't go to sleep. If I shut the lid and open it again it does a hard reboot instead of resuming from sleep.

          Mine goes to sleep when I unplug it from power

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

            sudo cat /boot/efi/EFI/fedora/grubenv
            # GRUB Environment Block
            saved_entry=a0a0a0b0a0000000a0a000000a00aaaa-5.3.12-300.fc31.x86_64
            menu_auto_hide=1
            boot_success=1
            kernelopts=root=/dev/mapper/fedora_user-root ro rd.lvm.lv=fedora_user/root rd.luks.uuid=luks-0aa0aa00-341a-0000-000a-a000a0a0aa70 rhgb quiet

                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

                  /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.

                                          @JaredBusch said in Fedora 31 stuck in a boot loop:

                                          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.

                                            @JaredBusch said in Fedora 31 stuck in a boot loop:

                                            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.
