Rerun a OS upgrade task Sequence after a user restart the machine ...

Question

Hi,

I created an SCCM task sequence to perform an in-place upgrade from Windows 10 to Windows 11. I deployed this task sequence to a test machine collection. On one of the test machines, the deployment appears correctly in the "Operating System" section. I then start the task sequence, and the installation begins successfully.

This task sequence is intended to be used later on approximately 2,000 machines. The goal is to anticipate potential deployment issues and observe specific scenarios, such as what happens if a user restarts the machine during the execution of the task sequence. To test this, I restarted my test machine during the installation.

After the restart, the task sequence no longer appears in the "Operating System" section, even after triggering all the available Configuration Manager actions. However, the machine is still part of the collection. I tried to clear SCCM cache, remove Task sequence folder on C drive root, but nothing reappear in the "Operating System" section ... I even tried to duplicate the existing task sequence and deployed it to a collection with the same machine, but nothing appear.

How can I make the deployment reappear in the "Operating System" section?
Thanks for your help,

Best regards,

Izanagi
