Grub not showing Fedora

Support

Hello, I installed Fedora 34 (Gnome) in a dual-boot setup of Manjaro KDE and Windows 10. After installation of Fedora, running sudo update-grub in Manjaro gives:

which is as usual. But after reboot, no Fedora entry in grub!
What is the issue here?

Try this method, using custom.cfg where you set a path to Fedora’s grub is the way I’d choose personally.

I will try this and inform the result.:slightly_smiling_face:

Just in case @openminded’s suggestion does not solve the issue already:

It could be that you installed grub from Fedora’s distro during installation of Fedora. In this case just sudo update-grub from Manjaro is not enough, you have to restore grub as described here:

Forgot to mention that in the original post, but tried it already and of no use in this case. :sweat:
