Newbie here, just made a back up (.tib file) of my local C drive and saved the image to my backup F drive which is a hard drive also. I would like to burn this image to DVD to use if I ever need to. Nero says unrecognizable format when I select burn image to disk. What do I need to do to get this done. If my pc crashes, do I just use the boot disk I made with True Image and it will let me install my saved image in place of my crashed one or do I still have to reinstall Windows?
