Hi people!
I have a read a lot of topics here on dual booting, but most handles Linux and Windows.
I use UEFI and my EndeavorOS is installed on /dev/sdc2 and my EFI partition is /dev/sdc1. openSUSE is installed on /dev/sda1 and uses the same EFI partition but I have trouble to get grub to find openSUSE. The command sudo grub2-mkconfig -o /boot/grub/grub.cfg does only show:
Generating grub configuration file ...
Found theme: /boot/grub/themes/EndeavourOS/theme.txt
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/intel-ucode.img /boot/initramfs-linux.img
Found fallback initrd image(s) in /boot: initramfs-linux-fallback.img
done
I now I have no clue what to do. I can change boot order in BIOS to boot into openSUSE but that’s a hassle. Anyone got any idea how to fix this?
Thanks in Advance,
Isak

This is looking interesting! I am going to reboot. Brb.

Strange that it doesn’t generate anything about openSUSE even though os-prober shows it exists. Is the os-prober showing the correct UUID for it? Try command lsblk -fm.
Here’s a workaround idea (that may or may not help):
You can copy a menuentry from openSUSE’s grub.cfg into EndeavourOS file /boot/grub/custom.cfg. It will show itself as a new menu entry at boot time.
First I must say I don’t have any knowledge about brtfs filesystems
If the distributions are on different disks, maybe you could mount that other disk with SUSE on it in the filemanager of EndeavourOS and once mounted then generate your grub.cfg file through EndeavourOS.
That contents can be written to /boot/grub/custon.cfg in EndeavourOS.
Assuming EndeavourOS is in control of booting, now you should see openSUSE Tumbleweed in the boot menu too.
EDIT: the openSUSE grub.cfg looks a bit strange for a btrfs system. Is this the latest available grub.cfg in openSUSE?
Why strange?
This is just the part where it boots openSUSE, if I change the boot order in bios the grub for openSUSE works just fine (only for openSUSE, does not boot Endeavor).
