Hey
I have made a multiboot system, with windows, fedora and EndeavourOS.
I have installed EndeavourOS as the last os.
When I log in, EndeavorOS grub cannot find the other boot options. I edited /etc/default/grub and enabled os-prober.
Now EndeavourOS can find windows boot option. But it can’t find fedora. What should I do here?
I have also tried fedora grub and it can find all boot options but it cannot boot into EndeavourOS. It comes up with an error saying it can’t find the kernel.
Fedora uses:
/boot
/boot/efi
/
/home
and so on.
When I had to install EndeavorOS, I mounted /boot/efi. And nothing else.
Did I do something wrong here? should i have mounted /boot too?
Ok, fedora grub shows all boot options. It just can’t boot them.
But for me it doesn’t matter what kind of grub I have to use, as long as it shows and boots them all.

Ah, I see. In that case that shouldn’t be an issue.
On another note, I’ve got a Fedora install, with everything on one and the same EXT4 partition. From an Arch install on the same disk, os-prober and grub-mkconfig seem to be working as they should, detecting and generating a bootable entry for Fedora.
I’m thinking of doing a fresh endeavourOS installation.
Where I this time, mount:
/boot
and
/boot/efi
The error fedora’s grub comes with is that it cannot find the kernel in /boot.
When I uninstall it again, I think that quite a few files will be placed on my /boot/efi partition from EndeavorOS.
Do you have an idea how I can clean it up. So that I ensure that I don’t delete anything from fedora?
It could also be that I should just install EndeavorOS on it in the aforementioned way. If that works, then I can reinstall both fedora and EndeavorOS?
There was a known “grub guy” (gohlip?) in old manjaro forums whose tutorials were great imo. I wanted to post the relevant one but those forums seems to be broken now?
It is not a good idea for multiple distros to share the /boot partition. Only /boot/efi should be shared.
And the solution is written a little further up. I have to create manual entries for each distro i want to see in the grub menu.
fedora and arch based distros don’t mix very well.
I am not sure what is meant by “mix” in this context. When it comes to use Arch’s grub to boot Fedora, as previously mentioned, I have no issues doing so. That being said, I should mention that my Fedora is installed in one EXT4 partition.
This is an issue with Fedora boot method, and nothing on Archlinux, or btrfs.
Fedora does not use normal upstream grub, but a seriously modified, using a different method (Fedora patent, a combination of grub and systemd-boot type of configuration, if I could give a short description), which cannot provide data searched by other distros grub/os-prober.
I don’t think FS makes a difference, but the fact that you probably use the Legacy grub method (same old grub), which is still possible. You might want to confirm this, when/if you find time.
@culcal only support option for this is at Fedora support forum, or documentation. They have instructions on how to use the Legacy grub method.
IAMOF, I was his student, assistant, and successor, as he has authorized me to continue his legacy
I have looked at some posts from the fedora forum. And they write more or less the same as you write about fedora grub and multiboot.
The solution is to make manual entries as @dalto mentions further up according to fedora-forum.
It’s fine with me making manual entries. It only needs to be done once, then it’s up and running.
The most important thing is that I can boot into the different distros from the same grub menu.
Sorry. I had just forgotten that you wrote that it works fine on your system.
What I meant by fedora and arch don’t “mix”. Was that their grub behaved differently. And according to fedorafrum its not possible to boot arch based distros from fedora grub.
The error message I get from fedora grub is that it cannot find the EOS kernel, in /boot.
But my EOS doesn’t have /boot partition.
Something tells me it will be worth the time to try to create a separate /boot partition for EOS, just like fedora has a separate boot partition, and then see if that works.
What I understand from the error message is that EOS has its boot directory, which is located in /root. And fedora is not looking there. It searches for the kernel in the fedora /boot partition.
So if each system has its own /boot partition then maybe it should work.
Of course I haven’t forgotten that it works on your system. And it might be because of EXT4 partition or maybe as @petsam mentions because of legacy grub.
