Is your external USB DVD drive plugged into a USB 3 Port? Google hints that that can be an issue. Corrupted install media can cause it too apparently.
Did you redownload the newest version of the Media Creation Tool? I ask because if you ran an earlier version (old copy) it won't download the latest build of Windows 10. And I do believe the latest build won't fit on a standard DVD. It needs to be a dual layer.
Seeing as Windows 7 was included in the free upgrade the MCT should have no issues being run on a Windows 7 PC. I'm pretty sure that's not why he's getting the missing driver message. Not 100% sure, but reasonably sure. If you go here, https://www.microsoft.com/en-ca/soft...load/windows10 and click the using the tool you'll see detailed info.
