My OSD Task Sequence got to install the OS and the SCCM client, and then just booted directly into the OS skipping the rest. No error was displayed, so I checked the SMSTS.log and saw the above error.

The new boot images comes with the new Windows 8.1 ADK (http://www.microsoft.com/en-US/download/details.aspx?id=39982) and R2 will upgrade them automatically.

The new boot images will look like this:
