Okay I want to install Windows 7 on one of my laptops which had HDD crash and issues with it. I've downloaded Win7 professional ISO from Microsoft website. How do I create a disc that I could use to install Win 7 on my laptop. I've already installed Win7 on my Mac mini using VMWare and it was easy to install with .ISO file that I downloaded. But I want to install on PC and need a disc that is an install disc and will be detected from DVD drive of laptop. I tried burning files from .ISO file to regular blank DVD but when I insert that DVD into laptop and try to boot from DVD drive it is not working. It says OS not found. I've Toast titanium but dont see option to burn .iso into installable DVD.
