Installing drivers on Win 7 from outside logging in?  

Is there a way to install drivers from outside windows 7. I installed a new mobo and now my mouse and keyboard don't work but I have access to my dual boot win 10.


Is there a way to install the drivers for Win7 from Win10? Or do I need to get a USB to PS2 adapter which apparently bypasses any drivers.

Hello Epicity

The documentation for installing device drivers from another Windows computer, is included in a link at the bottom of this post. The command you'll need to use is called DISM, and this command will tell you if something is not compatible with the image.
An overview of what you do is as follows:
1. From a Windows 10 command prompt, mount the offline Windows 7 image
2. Add the driver file to the mounted image.
3. Commit the changes to the image and unmount the image.
4. (Optional) Discard any changes to the image and unmount the image.
1
Dism /Mount-Image /ImageFile:C:\test\images\install.wim /Name:"Windows 10 Home" /MountDir:C:\test\offline
2
Dism /Image:C:\test\offline /Add-Driver /Driver:C:\drivers\mydriver.inf
3
Dism /Unmount-Image /MountDir:C:\test\offline /Commit
4 (Optional - instead of 3 above)
Dism /Unmount-Image /MountDir:C:\test\offline /discard

The actual pathnames you use will depend on your setup. Read the documentation for explanation.
