Windows Upgrade Error: Configuration sets are only supported when Windows installation is started from Windows PE.
I recently came across the following error when updating a machine from Windows 8.1 to Windows 10 – Error: “Configuration sets are only supported when Windows installation is started from Windows PE.”
In this case, the error was caused by the driver disk I had in the DVD drive. Removing the DVD fixed the issue.
Would be good if they were all this simple eh?!
