@Nev, I had the same error. The Microsoft link suggest to use the Windows 2008R2 disc, however the updates are on the 2012 disc. For me the solution was to perform the Microsoft solution with the Windows 2012 disc and reboot. The same goes for the ADPREP /DOMAINPREP updates.
Just cd to supportadprep on the Windows 2012 media and run:
You run adprep /forestprepfrom from 2012 media on the DC holding the Schema Master role in your forest. Then, you run adprep /domainprep and adprep /gpprepfrom the 2012 media on the DC holding the Infrastructure Master role in the domain that you're putting the 2012 DC in.
I just want to add that if the error still appear after doing theadprep /forestprepadprep /domainprepIt could be a problem in replication between the DCs (which was in my case) so also check the replication
