Dual Boot Windows 7/8 parallel to Ubuntu - The easy way

Are you using Ubuntu PC and want to install Windows 7/8/8.1 parallel to Ubuntu ?

It is easy to install Ubuntu parallel to Windows OS 7 [windows 8 is having some boot issue on dual boot with ubuntu, I am not going to discuss this now]. But, it's tricky to install Windows parallel to Ubuntu.

Yes, it's tricky but not impossible. "Nothing is Impossible, mind it... 

What you need ?

• Laptop/Desktop with atleast 4 GB RAM and 50 GB memory free
• Windows DVD/LiveUSB/LiveCD
• Ubuntu DVD/LiveUSB/LiveCD
• Internet Connectivity [for updating grup]

Lets go....

• First you have to make sure that atleast 50 GB of free memory is available to install Windows in it, resizing your Ubuntu using gParted if required
• Also use gParted or Disk Utility to format the the free space as NTFS, this prevents Windows  from creating an additional boot partition in addition to the "C" drive.
• Next, boot to the Windows DVD installer and install Windows on the NTFS partition. Upon reboot, Windows will automatically boot and you won't see the grub menu allowing you to choose Ubuntu, because the Windows bootloader has replaced grub.
• Now, what you need to do is run Ubuntu from LiveCD or LiveUSB and install boot-repair.
• To install boot-repair, open up a terminal by pressing Ctrl+Alt+T and type the following commands:

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

•  After installation, boot-repair will automatically launch, if is doesn't, launch it via Dash.
• Make sure to select recommended repair to repair grub. Reboot and that's it.
• You should now have a Grub menu on boot, allowing you to choose from Ubuntu, memtest, and Windows 7
