I am seeing that siple ISOs are not really working on Wind 7 ultimate. The
ISOs have UDF data in them and have to be booted from a DVD/R(W). Anything
to make things harder. Even ISOS made without UDF aren't showing up on my
OS. They aren't recognized or the OS says the USB stick is raw or full and
shows no data.
Check and make sure the required file system drivers are installed. Open
Command Prompt as administrator, then enter below command.
For the ISO file system:
sc query cdfs
For the UDF file system:
sc query udfs
Also, if you have DAEMON Tools installed, uninstall it. Because it uses a
driver which is know to cause CD-ROM related problems.
