In order to make an unmodified Windows Install ISO load the ISO file as a 'virtual DVD' so it can access the files on the 'DVD', E2B has to use an XML file with commands inside the XML file which tell Setup to load the ISO file.
Unfortunately, most Win8 and Win10 install ISOs require a Product key to be specified inside the XML file or else it does not work.
Why don't you just pick a generic SVR2K8R2 install key as already provided. Then once the OS is installed, you can manually enter your own product key.
The alternative would be to convert the ISO to a .imgPTN file using MakePartImage. Then no XML is used and no key is required and you can enter your own key at Setup.
