I have downloaded windows xp from a torrent site, and I want to burn it to a cd so I can use it in reformatting my pc. The windows xp file is in image file format (.iso) when I used nero to burn it the image file was directly burned in the cd, and I cannot use it to reformat my pc. What is the proper way of burning my windows xp image file so I can make my cd bootable as installer of windows xp?
