Hi and welcome to Sysnative,

I am checking to see if you still need help with this thread. If so please provide the complete CBS logs.

Upload a copy of the CBS folder

Open Windows Explorer and browse to the C:\Windows\Logs folder.
Right-click on the CBS folder and choose Send to > Compressed (zipped) folder.
Now the message will appear, "Windows cannot create the Compressed (zipped) Folder here. Do you want it to be placed on the desktop instead?"
Click on the Yes button here.

Attach the file CBS.zip to your next reply. If the file is too large to attach, upload the CBS.zip file to www.wetransfer.com and post the link in your next reply.
