Windows 8 - config default user profile

i am following the steps in this link

http://technet.microsoft.com/en-us/library/hh825135.aspx

However, before rendering the image, it ask for a image for catalog file to make copyProfile file.

*******************

If the Windows 8 catalog file doesn't appear in the Windows Image pane, follow the instructions inOpen a Windows Image or Catalog File.

********************

the image is yet to be rendered at this stage, where i find the catalog file to make copyProfile file.

Thanks a lot.
