Manual workaround method

You can manually work around the PXE reboot issue by creating the task sequence steps and groups and using the procedure that the Lenovo XClarity Integrator Deployment Pack uses to solve the problem.

The solution also involves creating a custom script that connects remotely to the Configuration Manager server (with appropriate credentials), accessing WMI, and resetting the PXE advertisement for the specific computer running the task sequence.

However, there is no need to do this work manually because the custom action described in the topic The Reboot to PXE/USB custom action sets up the task sequence for you.
