How to add another OS (ubuntu, windows, dual /multi boot,etc) on Archlinux Grub

By default if you install archlinux, there's only one OS to choose (Archlinux) on GRUB. To add another OS if you want to dual booting, the easy way is using OS-Prober. This will automaticly detect another OS.


OK just follow posts below:
1. Install OS prober
pacman -S os-prober


2. Run OS-Prober
After you install it. Then type os-prober, i have PCLinuxOS and OpenSuse installed on /dev/sda1 & /dev/sda3. os-prober will automaticly detect it. If it's not detected, try to mount "not detected os" partition first. Then os-prober again.
$sudo os-prober


3. Then Update the grub system.
$sudo grub-mkconfig -o /boot/grub/grub.cfg



Now another os can be boot using Archlinux Grub2. On my machines, PCLinuxOS, and OpenSUSE run fine.

Enjoy.
