Follow these steps from Ubuntu :

1. Open terminal by pressing Ctrl+Alt+T Or Search Terminal in Dash.

2. Enter the following command in Terminal :

   sudo gedit /etc/default/grub

   (This will open grub configuration file in gedit.)

3. Edit the file and change following options as following (remove comments # before any of below lines) and save the file :

   GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=10

4. Run the following command in new instance of terminal :

   sudo update-grub

5. Restart your computer, you should be now able to boot Windows if you did partition your system correct
