Norton ghost v15 image to bootable

I have installed v15 norton ghost  and created the backup with symantec image file  in E: drive (C is the windows system file) and now i need to create the bootable media to dvd to boot in case of any accident to windows.

 

I went to a couple of instructions says dos, windows pe , but v15 doesnot have those i guesss so. and also the image is other5 than .gho file

 

Thank you
