Windows: how to install driver from recovery command prompt?

For me pnputil.exe did not do the trick. However, I found the following command, which helped: dism /Image:C:\ /Add-Driver /Driver:D:\ /Recurse. This assumes that your Windows is installed at C:\ and the disk with the driver is present at D:\. This appears to even work, if the disk contains drivers for different architectures (x86 and x64) and operating system versions (XP, 7, ...).

use pnputil to add the driver to the driver store. Windows now detects the driver:

pnputil.exe -a C:\<filename>.INF 

And you should add the drivers before changing the mode.
