GNU/Grub

Grub dual booting

Grub does not use os-prober per default anymore and you will need to enable it in grub configuration to have other OS’s listed in the grub boot menu.

First, make sure os-prober is installed and if not install it:

sudo pacman -S --needed os-prober

then edit the main grub configuration file by adding:

GRUB_DISABLE_OS_PROBER=false

to

/etc/default/grub

and regenerate grub.cfg

sudo grub-mkconfig -o /boot/grub/grub.cfg

—> Check if this is still needed, as we went change the installer to enable os-prober usage per default again. (09-2021)
