Dual Boot Windows & ChromeOS using GRUB - Bare Minimal Setup

In this video I have shown How to dual boot windows and Chrome-OS without installing some random software in Windows machine. I saw may videos in which they use grub2win. But I find it some what uncomfortable at least for me. I like the Grub2Win software also to mention it is an opensource software. This a common PC in my home so It should boot to windows seamlessly. So I made Grub to boot into Windows and Chrome-OS while keeping the windows as default one.
