"offline copy" as in the windows installation that you are not currently 
running.
dism cant be used on the currently running windows instance.
booting to recovery is enough, this recovery can be from a usb stick or 
install dvd or whatever you prefer.

example:
dism /Image:C:\ /Add-Driver /Driver:X:\drivers\ /Recurse

assuming C:\ is the drive where the broken offline version is.
check drive letter, it might not be what you expect.

also, this is not really vfio specific things, so probably a bit offtopic.

and as i said before, all this will do is to add drivers, like those 
needed to find your boot device.
