On the client being imaged, the following error was experienced:
The Windows Boot Configuration Data (BCD) file from the PXE server does not contain a valid operating system. Ensure the server has boot images installed for this architecture.
Error Code: 0xc0000098
This issue occured because I installed The Windows Assessment and Deployment Kit (Windows ADK) version 1709 on the server.
SCCM 1702 does not support ADK 1709.
To fix the issue, I simply performed the next step of the upgrade - using the SCCM console to perform an in-place upgrade of SCCM to 1710.
For future reference:
If your running SCCM 1702, make sure you run ADK 1703.
If your running SCCM 1710, use ADK 1709.
Hope this post was helpful.
