Troubleshooting GRUB2 To Dual boot Fedora 16 with Windows 7

just installed fedora 16 and a bit shocked when my windows is not in
the selection menu.
i found this and the solution is just a one liner command only. thank god.
make sure you have os-prober installed.
and type this command :

su -
grub2-mkconfig -o /boot/grub2/grub.cfg

this will put in your windows automatically in the selection menu.
