The current information for resetting and reinstalling grub2 is out of date:

https://docs.fedoraproject.org/en-US/fedora/latest/system-administrators-guide/kernel-module-driver-configuration/Working_with_the_GRUB_2_Boot_Loader/#sec-Resetting_and_Reinstalling_GRUB_2

This doesn't address the BootLoaderSpec layout or the fact that the grub.cfg file generated by grub2-mkconfig is in /boot/grub2/, not the EFI partition. There's a separate minimal grub.cfg in the fedora directory of the EFI partition, but that's not the file to edit if things are going to be reset.

It also references /etc/sysconfig/grub, which is removed in Fedora 36.

I also saw a recent kernel update (or maybe it was an update to F36) mangle my grub entries by putting stuff in the EFI partition mounted at /boot/efi instead of directly in /boot. When it did so, it created a subdirectory for the machine-id, and the kernel and initrd in a subdirectory based on the kernel version.... none of this new layout is described anywhere in these docs.
