Time for a small mea culpa.
The original lab environment for Learn SCCM 2012 R2 in a Month of Lunches used Windows 8 as the client operating system, not Windows 8.1. When Windows 8.1 launched I quickly switched operating systems in the hydration script so that readers would be using the latest client OS, but I missed updating the LAB-CLIENT01 task sequence.
As a result, when you go to deploy LAB-CLIENT01, you’ll hit an error. There are two ways to resolve this.
Option One – edit the LAB-CLIENT01 task sequence and change the “Install Operating System” step (which will be in an error state) so that the operating system to install is “Windows 8.1 Enterprise x64”. Update MEDIA001 to regenerate the ISO and you’ll be good to go.
Option Two – download the updated hydration script here – this has the correct LAB-CLIENT01 task sequence. Then, either re-run the hydration process again, or simply copy ..DSControlLAB-CLIENT01ts.xml to the MDT Deployment Share and replace the one which is already there. Again, update MEDIA001.
Thanks to Chris van der Lugt for bringing this to my attention – much appreciated 🙂
