If you don't want to go the torrent route.
1. You can try calling MS for a replacement disk. https://store.digitalriver.com/DRHM/...en_US&Env=BASE
2. You can download the Windows 7 iso file directly from Digital River, one of the delivery partners for Windows 7, burn it to a disk using Imgburn, or any burning software, like my favorite, Ashampoo Burning Studio. http://www.dxdo.com/2010/softwares-o...editions-free/
Of course you will need a valid Win 7 product key.
