I have tried searching the forum but found no help. I just installed Win 8 Pro over Win 7 Ultimate. It installed everything, however when it cam to Personalize screen the mouse and Keyboard stopped working. I cant even sign in. However I was able to restart and get into the Advance Options and the mouse and Keyboard works in the advance option.

I even did a automatic repair but did not work, every time it boots up the keyboard and mouse stops working, I am sure there is a way around this.. there are no recovery images since its a new install, You help is much appreciated.

1. Look into Device Manager and check if all devices are installed correctly.

2. Look into Event Viever if there is any error or warning that may explain this behaviour

3. Look into MS Hardware compatibility list if your USB external devices are on the list.

4. Test your computer with differenet mouse and keyboard.

5. Make sure, that screen resolution meets the minimum required one.

I don't think we get devmgmt.msc in WinPE?  What I'm wondering about is whether wmic is there?  In W8 supposedly we can use PowerShell, how ever that might be used for this task.

In W8 "PowerShell 3.0 optional component added."

(BING search for
    "Windows Preinstallation Environment" "powershell 4.0"  site:microsoft.com
)

Windows PowerShell 2.0, Windows PowerShell 3.0, and Windows PowerShell 4.0 run in the Windows Preinstallation Environment (Windows PE).

But for this particular symptom I vaguely recall that there is a log being created somewhere (Panther directory?) which showed that the setup was discarding device support and neglecting to notice that at the end it had discarded all possible HID!

Some have somehow managed to use Remote Desktop to control their "headless" W8 but I think that that scenario happens later after the OS is fully installed?

But does this prompt really matter?  What else would be left to do for the install?  Couldn't they just boot?   FWIW I don't have a test machine I can play with to understand this scenario better.

 
FYI

Thank you all for your reply, none of the above worked!!! However I was able to resolve this by the following steps below

> Restarted the system using Shift+F8

> Clicked on Troubleshoot

> Clicked on Refresh Your PC

> Once the Refresh was complete, Windows 8 restarted and the Keyboard and Mouse were working fine.

> Customized my setting and everything works normal.

Thanks for you help guys.. If you can can suggest this to others users maybe this would help other as well..
