Grub doesn't recognize Ubuntu, only sees Arch (dual boot)

I was just following the beginner's guide and installed grub as it says.

# pacman -S grub os-prober
# grub-install --recheck /dev/sda
# grub-mkconfig -o /boot/grub/grub.cfg

and I forgot to set it up so that Ubuntu and Arch are available in Grub. I had Ubuntu on my machine originally am trying to install Arch along side it so I can dual boot them. How do I fix this?
