I am trying to burn a Windows 7 ISO file I downloaded from Side Micro onto a DVD-RW using Imgburn, and get the message "There doesn't appear to be enough space on the disk to burn the image." The number of sectors in the file is: 1,251,484 2,444 MB The number of sectors on the disk is: 859,847 702 MB Can I break this up to put it on several disks? And if so, how?
