Grub not Detecting Artix after installing another Linux Alongisde

I had Artix and Windows 10 installation before. After that, I installed Arch Labs in the Windows partition(sda2).

Now, after successful installation when the system restarts, Grub doesn't show Artix entry. Artix is on sda5.

I ran
Code: [Select]
sudo grub-mkconfig -o /boot/grub/grub.cfg
but still doesn't help.

Here's the output of the above command:

Code: [Select]
[archlabs@archlabs ~]$ sudo grub-mkconfig -o /boot/grub/grub.cfg
Generating grub configuration file ...

What should I do next? Thanks in advance.

It would help to have more information. Does your computer use BIOS or UEFI? Also, what is your partition scheme?
Although it's obvious, have you tried checking the boot options the BIOS Menu Settings/UEFI Firmware Settings to see if there are multiple GRUB entries?

Try to look here:

Also, IIRC, grub won't find another installed system if it is on a btrfs subvolume.

FYI: update-grub is a wrapper for grub-mkconfig -o /boot/grub/grub.cfg.

Yes both Linux partitions are Btrfs. So what should i do next?

If you use just plain btrfs partitions, just follow the guide I've posted link to above.

If your systems are installed onto btrfs subvolumes, tough luck, grub won't find other systems automatically. You'll need to add grub menu entries manually (there are some guides on the Internet on how to do that) or use UEFI boot loaders instead of BIOS and choose your system during startup using the UEFI menu.
