MECM v2111 - Boot images

So this is what I learned. The act of adding drivers to a boot image and updating distribution points will not change the boot image that is downloaded.

After I updated our test boot image with drivers, I needed to test it with a different task sequence to validate the problem is resolved. This is what messed things up. I created a new task sequence, went to properties to assign the test boot image and clicked on Apply. At that moment, I changed which boot image downloads first.

To fix this issue, you need to locate the last task sequence deployed. In my case, it was the test task sequence I created and deployed making it easy to resolve. If you don't know which of your task sequences was deployed last, you can look at the Deployment Start Date of each task sequence in the console to find it. You can either update the last task sequence's properties with the correct boot image or you can delete the deployments for a task sequence using the desired boot image and deploy it again. This will change the boot image downloaded to the version you prefer.

Here is a query that will show you task sequence deployment start dates in your system:

SELECT v_Package.PackageID AS [PackageID], v_Package.Name AS [Task Sequence Name], v_Advertisement.PresentTime AS [Deployment Start Time]
FROM     v_Package INNER JOIN
                  v_Advertisement ON v_Package.PackageID = v_Advertisement.PackageID
WHERE  (v_Package.PackageType = 4)
Order By [Deployment Start Time] DESC

Lastly, you can read up on this more by checking out this article -> https://docs.microsoft.com/en-us/mem/configmgr/osd/deploy-use/use-pxe-to-deploy-windows-over-the-network#how-the-boot-image-is-selected-for-pxe

Thank you for replying and I hope this helps out everyone.
