ISO-13346 "UDF"

I have Vista and am attempting to upgrade to Windows 7. When I insert the Windows 7 installation disc the following README TXT message comes up. "This disc contains a "UDF" file system and requires an operating system that supports the ISO-13346 "UDF" file system specification. I'm assuming Vista supports this system.

Answer
There are a number of possible applications you may have installed. Nero 7 and others, for work with that drive. You will know what you have by looking in the Programs and Features app in Control Panel. I would try removing those kind of applications one at a time and restart to try the disk.
