[SOLVED] Windows Grub deleted after installing Android/Linux

I found Android as a best operating system in mobile.So,i want to use the Android OS in my PC.Then I found that we can use it by downloading the iso file of Android and use it without installing in the computer. I burned it in the DVD and when I opened it, my previous Windows Grub was gone..I was a little bit tensed for a while coz all my data and all other programs were gone.
              I thought of formatting my windows but it is a long process and will take more time to install all the drivers and programs.Then,i found a easiest way to recover my previous windows grub.I tested it and found that it was really a good technique to recover my previous data and my operating system.
Here i have listed the procedure:-
   The process is same to recover your grub after installing android or linux.
