Extract Ent or Std from a dual Ent/Std disc?

[warpkez]

When I was subscribed to MSDN, I would receive multi-boot CD with various versions of Windows Server 2003.

In this instance, I have one that has both Enterprise and Standard. What I am wanting to do is extract the files necessary so I can create individual CDs with the appropriate updates.

I have tried using copy and xcopy, but I end up with all files being 1KB in size, including executables; I have attempted using nLite, but during the creation of the ISO, some files are missed in particular the EULA.

Is there a way to create seperate trees for Std and Ent?
