Have a working Windows installation at C:\Windows. However, due to a hardware change, it won't boot (missing driver(s)). Can I somehow install a driver to that environment, without being able to boot to it? (Maybe via dism /add-driver from WinPE) Thanks
Hypothetical, in a way. Someone attempting to move windows installation to a completely new hardware (mobo, cpu, ram, etc) environment (yes, i know, bad idea).
Yes, you should use Dism. Do you know which drivers are required? If so, try this: - Create bootable Windows install media (USB, for example) - Add a folder like "MyDrivers" to the root of the install media, and put all needed drivers inside (make sure they are extracted .inf and .sys files) - Boot from the install media and in, WinPE, start Command Prompt by pressing Shift+F10 - Run Dism like this: Code: dism /image:C:\ /add-driver /Driver:X:\MyDrivers /Recurse Where "C:\" is where the OS is installed (Windows folder) and "X:\MyDrivers" is where the new drivers are located. You will have to find the appropriate drive letters, for your specific case. The "/Recurse" argument makes sure that all subfolders are scanned for inf files to install.
