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)
