The only dumb question is the question that was not asked =P
Anyways, I am having a hard time understanding your question.
Are you trying to install windows on to the hard drive?
If you are, then you can not install on to a dvd player.
You need to create a new partition on the hard drive, but it appears that it is not detected.
If you are trying to create a backup of you windows disk, then the disk you are using has something on it already and you need to get a different one.
