Hello @JSW ,
Thanks for your query.
Task sequence may not finish successfully or has unpredictable behavior. The Install Operating System task sequence step or the Apply Operating System Image task sequence step may have been modified after the creation of the task sequence step can lead to unpredictable results. It is recommended that a new task sequence is created to deploy a different operating system image.
