Does native Windows 7 really have a UDF file system driver
? Perhaps you're on to something here. While I don't recall installing any CD/DVD burning software, I'm going to do something really radical to test out your theory. I'm going to take an Acronis image of my system and then completely wipe out that installation by doing a bare metal, fresh installation of Window 7. As you know, being a Windows 7 geek yourself, installing a new copy of Windows is not that time consuming, it's all the customized settings - email addresses, Outlook rules, etc, etc - that really take up the time. With a virgin copy of Window 7, I should be able to start the install disk within Windows and setup should start up. If I get the same thing that I'm getting now, then I will have eliminated your theory.
I'll try it out and get back to you.
Thanks for your creativity in search for a solution.
