There is some problem with my pc.At present I don't have my windows 7 ultimate DVD but have downloaded all the folders of the dvd in a separate document. I now want to format my pc and reinstall windows in it. So I want to transfer my windows to a DVD and make it bootable .

Where did you get Win7? Did it come preinstalled on the PC so you can Clean Reinstall - Factory OEM Windows 7?
