Hi. There are three systems on the disk. Windows stood for a long time, now I installed arch on sda5 and immediately Manjaro on sda6. Both are encrypted. Grub sees Manjaro and Windows, but not Arch. All systems boot normally via uefi. What should I do in this situation? I’ve already tried it
grub-mkconfig -o /boot/grub/grub.cfg
Since the systems are encrypted, they can’t be accessed without the decryption key. That is why your 1 grub can’t access the other Linux, so according to it, there’s nothing boot-able there.
I suspect you’ll have to add the other distribution manually in /etc/grub.d/40_custom. No, I don’t know how.

Either that or, and here I again don’t know if, or how to do it, but either that, or the boot partitions for both distributions need to be on an un-encrypted partition.
Personally, I’d say this is the best option if you have to have encryption. Leave the OS un-encrypted and encrypt just your data.
And please do not post pictures of text.
For grub to be able to identify other systems it needs access to the system’s root filesystem.
Logically - this is not possible when the root filesystem is encrypted.
So no matter what you do - os-prober will never be able to identify what is inside a luks encrypted block device.
The only way you can have a dual system using encryption is to use a unified kernel image stored as an efi image - then you can boot it using your systems boot override.

Could you please explain in a little more detail what it is so I can figure out for myself if it’s worth it
I educated myself on the topic and wrote a topic to share how I did it.
