Running sudo qubes-dom0-update --action=reinstall $(rpm -qa --qf '%{NAME}\n') which results in reinstalling every package, completely destroyed my grub menu, again. Mostly worked with two exceptions related to kernel packages, but I don’t remember the exact error message. Didn’t cared much, as I had plenty of other kernels for booting if something fails. Well…
Because I already had some experience with grub related issues, I wrote the Qubes Iso to an USB, entered the grub rescue mode, mounted everything and tried to run grub2-mkconfig -o /boot/efi/EFI/qubes/grub.cfg though this didn’t helped. In second instance I tried reinstalling the packages again since they are still cached so that other kernels could write themselves into the grub menu. And actually I received the output that I got an new boot entry but when testing it, it still just shows one entry, the UEFI Firmware Settings instead of Qubes.
Honestly, I don’t think it will help, but running grub2-mkconfig -o /boot/efi/EFI/qubes/grub.cfg is not exactly the correct way to update the grub menu, so, maybe you can try the following?

Still just shows UEFI Firmware Settings after reinstalling grub, trying an older .cfg and regenerating the initramfs. To make it more easier, how can I add Qubes in Grub from another HostOS?
I will try it tomorrow though I think there is a communication mistake:
UEFI has a functioning Qubes entry. My Bootloader/Grub hasn’t. Usually there are three options, booting Qubes, booting Qubes but advanced and UEFi Firmware Settings. The first two are missing.
Well yes you are missing output of /etc/grub.d/20_linux_xen in your automatically generated grub config. You probably should check on it.
Whoever posts a link to qubes repository containing 20_linux_xen on github here would be really helpful, I cannot find it
It’s a generic fedora package file, I’m not sure which would be the best pick for you, search here: fedora build system - grub2-common. Probably any build for f37 will do (assuming you’re running qubes 4.2).
Oh no build 2.06-4 have been deleted. I suppose you could download qubes iso, mount it and get the file that way
The grub shell just resets itself. I’m close to giving up, but before I want to redo everything I tried so far in case of an misstake.
If you/anyone has any new idea, you’re welcome.
So fucking thank you, it appears that dnf reinstall deleted the vmlinuz files while not recreating them. Uninstalling and installing the kernel solved the issue.
