Hi All,
I'm running into this issue sporadically over a noticeable number of computers, but consistently on the computers that don't work.
While running a task sequence, the applying OS step fails saying:
"WIM error:C:\[Filename].
Windows cannot verify the digital signature for this file."
I have tried recapturing the WIM, disabling AV on the server, refreshing the DP, updating the DP, cleaning the drive in Diskpart as well as doing a low-level format using DBAN and nothing has solved it. What is strange is that through hundreds of computers, only a handful fail and result in a BOOTMGR is Missing error. But for the ones that do experience it, it is a consistent failure. And for the successful ones, it is consistently successful.
