Setting up your Computer & BIOS changes ( If required)
Now reboot your computer after popping in the all new Windows 7 DVD you just created in to the DVD Drive. In most cases if you do this you'll automatically boot in to the Windows 7 Installation DVD. But in some cases if the Boot device order is changed in the BIOS it may boot in to your older OS, instead of our DVD. In that case you'll need to change the BIOS settings to gt it done ( More details in a different tutorial).
