I am getting error when deploying W7 from SCCM. The error from sms log said "Failed to run the last action: apply operating system. Execution of task sequence failed. Element not found. (Error: 80070490; Source: windows). So I went to check the operating system object's image properties and trying to change it from 1-1 to 2-2 under Select image you want to view dropdown box but I am unable to change it. I am able to update the OS image to 2-2 on task sequence. I deleted the OS from sccm and reloaded it but i still can't Apply the change to 2-2 in image properties. The actual windows is on 2-2. Any advice? Thanks
