I remember I had a Grub hook some time ago (a hook to automatically manage the Grub stuff so it won’t break), maybe it was copied along with the files I had as backup on an external drive then I copied /home/limo/ from that external drive after I installed EndeavourOS on this new laptop.
UPDATE:
I checked an old thread Grub Hook to grub-install and grub-mkconfig? and found I have grub_update.hook at /etc/pacman.d/hooks/
Now, I think I should delete it, right?
What commands to do to completely get rid of Grub and ventoy and any of their traces?
