I used this many times as the bootloader gone corrupted after the install and it was only possible to start in Linux but not in Windows after the Linux install. So you should do following to get it right.
Execute following commands in Linux:
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install boot-repair
That will start the boot-repair use the defaults and ckick further next in the menues. It will repair the bootloader. After that it will be possible to start the both Linux and Windows from bootloader.
