Need help with disk with all versions

[optimus1337]

I need to make a disk with all versions excluding the "n" versions; but all I ever get is the last version that I selected before I make the iso.

I have an OEM copy of vista with sp1 already integrated and I apply some tweaks (disabling UAC) and set up my unattended parameters to each version, choosing "Save Changes Only" when I apply the changes to each version; on the last one I choose to "Rebuild All" and I make the iso. The problem is that every time I do it all I get is the last version that I selected.

I have tried with x86 with sp1 already slipstreamed and x64 slipstreaming sp1 using vlite both OEM versions

Im sure this has been addressed somewhere but I just can't find it. I have followed the tutorials to the best of my understanding as well; but they don't go into much detail and are especially vague on the iso creation stage. Thanks
