Hey, so i’m having an issue with trying to duel boot my system, i currently have EOS and Kali Linux installed on my system, but Kali Linux never shows up on the Grub i have tried using os-prober and it does not seem to detect it and yes i did mount it.
i also tried manually adding it, It shows up but refuses to actually boot into the OS
Any other suggestions searched high and low for a solution but cant find anything.

No, that would be overwritten each time Grub is updated. Make instead a custom.cfg file in /boot/grub and add the menu entry to it. No need to update grub afterwards.
