jconverse Posted September 25, 2013 Share Posted September 25, 2013 I used ImgBurn to create an ISO file from my Windows 7 Upgrade disk. It seems to create the file OK, but when I try to read it with Microsfot's Windows 7 USB DVD Download Tool - it says not a valid ISO file. Any ideas on what's happening? Thanks.........

LIGHTNING UK! Posted September 26, 2013 Share Posted September 26, 2013 Maybe their tool doesn't support the 'upgrade' disc? Link to comment Share on other sites More sharing options...
