Fedora entry not in its own Grub Menu

I installed Fedora 35 beta version, and I decided to set up btrfs snapshots, so I created subvolumes, copied stuff to their respective subvolumes edited fstab, deleted fedora’s folder from /boot/efi/EFI, chrooted into fedora from my Garuda installation, reinstalled:

dnf reinstall grub2-efi grub2-pc grub2-pc-modules grub2-tools-efi grub2-tools-extra shim

updated grub:

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

Everything went fine, even fedora’s grub shows, but the grub(fedora’s own grub) doesn’t have fedora’s menu entry, but other distributions in it, so I can’t boot into fedora right now.

Was /boot/efi mounted in Fedora when making grub2-mkconfig ?

Yeah /boot/efi was mounted.
This is how my fedora grub looks like:

Even fedora 35 still uses /boot/efi/EFI/fedora content. F34 relocated grub.cfg to /boot/grub2 but efi/EFI still contains several files related.
This shows files related to the latest kernel update even though several are holdovers from the clean F33 install that was done in March this year.

I tried: grub2-mkconfig -o /boot/grub2/grub.cfg but still no luck

https://fedoraproject.org/wiki/GRUB_2

The GRUB configuration file is located at /boot/grub2/grub.cfg and is intended to be a static file that does not need updating. In case of disk replacement, or installation of another Linux distribution, /boot/grub2/grub.cfg should be updated. Use the following commands:

sudo grub2-mkconfig -o /etc/grub2.cfg

sudo grub2-mkconfig -o /etc/grub2-efi.cfg

These commands use the information provided by the os-prober utility to add entries for other Linux distributions and Windows.

Thanks @computersavvy

When I ran the similar grub-update command, I got a long output as if grub was never used or grub was never there! Does everyone do this kind of output when they try to run grub-update? (In Ubuntu, I hardly get 4 lines of output when I ran sudo update-grub.) What is the output trying to say? Is it normal to have such output?

  ⟹  sudo grub2-mkconfig -o "$(readlink -e /etc/grub2.conf)"

I suppose we have to run:

sudo grub2-mkconfig -o /etc/grub2.cfg

sudo grub2-mkconfig -o /etc/grub2-efi.cfg

You can give us the output of these commands

you have run

sudo grub2-mkconfig -o "$(readlink -e /etc/grub2.conf)"

Yes, I got that command from the most upvoted answer from here: What is the equivalent of 'update-grub' for RHEL, Fedora, and CentOS systems? - Unix & Linux Stack Exchange

I hope the command is safe to use, isn’t it?

Actually, you just have to run

this command is just checking whether the file /etc/grub2.cfg exists or not, in your case as in the output you have given the file exists, actually, this wasn’t necessary to check if you were running fedora >34.
