How to add second linux to grub?

Question

linux

The point is this. Rolled on the Fedora laptop, the main system one. Of course, I set automatic layout to the only section at that time. On a partition with a root of 400GB. I bit off 200 into a separate section and rolled Kali onto it (I will immediately answer the questions "Why do you need Kali?" - there is a need for software). I don’t want to set Kali as the main system (Fedora is more pleasant for me and I set everything up according to the new vlomy). Let's get back to the problem. How do I bring Kali into GRUB Fedora?

Advisers on Habré (on the topic of Linux) eat at least one place, but there are few sensible x @ d. Thank you for trying to help Uneasy Hearts Weigh the Most in any way !
Everything was solved with one command:
grub2-mkconfig -o /boot/grub2/grub.cfg
(however, they like to distort the documentation on the forums, but by the way, it https://docs.fedoraproject.org/en-US/quick-docs/ bo... )
The Kali kernels were successfully picked up, but the firewood decided to fly away. Since the laptop has everything from AMD, I added proprietary drivers to this case ( https://packages.debian.org/buster/firmware-amd-gr... ).

Thanks to this house, I will go to another!
