MX-Linux doesn't see Arch Linux in grub [Solved]

[popjah]

Hi:
This solved it for me with another distribution installed in btrfs that in the MX Grub was not visible, try to create an entry for the @root partition of Arch, see if it works.

Hi Senpai,

Thanks for your tip; tried it but it didn't work in my case.

@popjah

... tried rEFInd some time ago but didn't like it ...

Ok, but did it work?

If you like it's possible to create a custom entry

Or if you like just install grub on Arch (let it control it) .

Yes, rEFind worked fine! But there was something I didn't like about it, I forgot what it was. But why not, I'll give it another go, thanks for the reminder!

About installing grub on Arch, how would I do it (never done this before)?

Cheers!

Ok, will try, thanks!

I know it may look confusing.

But if you like this may be even simpler: You can post the grub.cfg ( /boot/grub/grub.cfg ) "of Arch" then we pick the related lines and simply paste into custom.cfg ( /boot/grub/custom.cfg ) in MX. (At least no harm to try).

Deal, and thanks again!

Right-click on /boot/grub/custom.cfg on MX: "Edit as root" , paste this, save, reboot.

Hurray! Worked perfectly, together with an Arch logo in the boot menu!

A final question: do I have to worry about anything if Arch updates the kernel, etc.? Will I have to change a specific line in the created /boot/grub/custom.cfg file (I had to create the file because it didn't exist)?

Many thanks for solving this, Charlie Brown!

I was just going to write that. If you change kernel etc. you need to do (kind of "update") it again.

However unlike MX / Debian no kernel versions stated:

Code: Select all

linux	/vmlinuz-linux-lts
initrd	/amd-ucode.img /initramfs-linux-lts.img

So, first compare the new grub.cfg and do it if necessary. You can simply take this part (between these two)

Code: Select all

### BEGIN /etc/grub.d/10_linux ###
...
...
### END /etc/grub.d/10_linux ###

On MX just saving the file is enough, no need to update-grub :)
