I am currently running sccm 2006 on server 2012 R2 with MDT 8456 and ADK 10.1.19041 My current issue is with the sccm boot images. When I go to the properties of any of the boot images the drivers tab is missing. Also I tried to add a driver to the boot image from the drivers section under Operating systems, none of the boot images show up. I tried to reload the boot image and that did nothing. I have uninstalled adk and reintsalled and no changed. I uninstalled mdt and reinstalled and no change. I tried to create a new boot image but it is still missing the drivers tab in the properties. Has anyone seen this issue before?
