Editing grub Menü dual boot not working

Heavybell, 5 months ago

I’m a gentoo user, so I don’t know how either manjaro or arch lay out their partitions. But in my case, the grub.cfg (menu) file is actually on the root partition, in /boot. The efi partition contains only the grub loader, which I presume knows where to look for grub.cfg because that’s how grub2-setup installed it.

It’s possible you have a similar issue. Your manjaro partition may have a /boot dir which is where grub.cfg is located. Even if your arch partition also has /boot it won’t matter if the grub loader doesn’t read it.

You’re correct. /boot is the location for grub.cfg for a vanilla manjaro install and a grub using arch install

Show df -h from Manjaro and Arch please.

I got it to work…

I have used the command grub-install --target=x86_64-efi --efi-directory=esp --bootloader-id=“Arch Linux” before, but without success. This didn’t worked before. But now…

I have no idea, whats changed. Anyhow. Im happy.
