Windows Server 2008 R2.
When I attempt to create a new "simple volume" in Disk Management (or even Diskpart), the operations hangs and eventually end up with this error:
However, before the error above appears, I noticed that in Device Manager appears an Unknown device (under Other Devices), if I right-click on Unknown device and select Update Driver Software, and I browse to C:\Windows\inf, it actually finds and detects a Generic volume and the new "simple volume" ends up being created just fine.
It's as if Windows has lost the ability to look for drivers in C:\Windows\inf by default.
Can anyone suggest how to fix this?
The answer is here: https://docs.microsoft.com/en-us/windows-hardware/drivers/install/where-setup-searches-for-drivers Somehow C:\Windows\inf was missing from the DevicePath key.
