Fixing a grub & os-prober issue
This article deals with the situation where there are other Arch based operating systems already installed onto a machine, and EndeavourOS is then installed to that machine.
There is a long-standing and annoying issue with co-operation between packages
os-prober. The generated
/boot/grub/grub.cfg file fails to boot some Arch based operating systems!
The reason for the issue is how
grub-mkconfig command generates the
initrd lines into /boot/grub/grub.cfg. On Arch based systems there may be more parameters for the initrd line than simply the initramfs image: the microcode image. And that is not generated properly along with the initramfs image.
For example, when using a microcode image, this kind of initrd line should be generated by
initrd /boot/intel-ucode.img /boot/initramfs-linux.img
but instead, this is generated:
And that particular boot menu entry fails to boot!
The fix is using the EndeavousOS package
grub-tools. It will fix the co-operation error in the implementation of
To fix the
grub-mkconfig command on your existing installation, the following commands must be executed:
sudo pacman -Syu
sudo pacman -S grub-tools
sudo pacman -S grub os-prober
sudo grub-mkconfig -o /boot/grub/grub.cfg
After reboot the menu entries should work as expected.
The first official EndeavourOS ISO of the year 2020 includes this fix. So all installs created with this ISO (or newer) will have this issue fixed by default.Connect with us:
