Hello, I have a single disk with a Fedora and Manjaro installations.
Fedora is encrypted (single btrfs partition) and was installed first. Grub2 was initially installed by Fedora. I think installed Manjaro (unencrypted) and was hoping that the installer would recognize Fedora and add it to the bootloader. It didn’t.
Now I want to add Fedora to the Manjaro boothloader that shows up at the beginning. Since Fedora is encrypted, when I run os-prober, it does not show up unless I mount it and make it available first.
Once I do that, I see this:
sudo os-prober ✔
/dev/mapper/luks-6aeadffd-de0f-43a3-8db2-5368e0a347b7:Fedora Linux 36 (Workstation Edition):Fedora:linux:btrfs:UUID=b5fc9ab3-ac9b-4eb9-bd4c-cfa47c600a1e:subvol=root
After the above, I have run update-grub, but still do not see Fedora added.
