How to configure grub from another linux installation

I remember being using systemd-boot, one day I installed in another partition in the same disk debian which installed it's own grub and it didn't make any problems for me so I let it as it is.
The problem is that I don't know how to configure grub from arch (I want to make arch the first entry in grub), does somebody know how to do it? please help

There is no directory for grub in /boot :
ls -R /boot |grep -i grub
grub.cfg
grubx64.efi

Re: How to configure grub from another linux installation

The quick and dirty solution: Find the grub configuration file.  Probably at /boot/grub/grub.cfg and edit it with the proper permissions.  look for a line that says 'set defualt="0" '.  Change that number as appropriate.

The more correct solution would be to reinstall Grub from the Arch side.    Or, go back to Debian and change the default there and update GRUB from there.

Re: How to configure grub from another linux installation

Thanks for consideration. Reinstalling Grub was easier for me, I also read these https://wiki.archlinux.org/title/GRUB#GRUB_removal and https://wiki.archlinux.org/title/Unifie … efibootmgr so I learnt about efibootmgr too.
