+## Winboot
+Tiny script to reboot the system to a windaube partition.
+
+Be sure to set the correct value to **WIN_GRUB** variable which must be the number of the windoze partition in Grub. Be careful, the grub's entries start at 0.
+
+* The script will also modify the grub configuration :
+  * Set Grub in "saved" mode.
+* Then for the reboot :
+  * Choose the grub entry for the next reboot.
+	* Reboot the system with ``systemctl``.
