Hi,

I need to maintain two configurations one is with Windows 10 & another one is with Windows 7 both are 64 bit. This I will achieve by HDD swapping. My windows 10 configuration is working fine. If I swap the HDD for Windows 7 installation then my keyboard and mouse not working in windows but works in bios. If I try to install OS from DVD/CD drive, I am unable to access the frame because Keyboard & mouse is not getting detected.

What could be the problem? And How to solve this?

I tried with some other internet links but it was not helpful.

Hi

Legacy mode is enabled and the keyboard mouse is working perfectly while boot/bios. 

How i will delete the drivers? As I am unable to login to the system.

Hi,

I have tried the steps  which was specified in the attachment. Now I can able to install the windows 7.

But after installation while doing initial steps for OS configuration it is not working...:-(

If anybody knows this please support.

Hi,

Solved  I have sorted out the issue... I am posting here because everyone will make use of it. In future if someone faces similar problems then it will be helpful.

Because the manufacture removed USB 2.0 support in chipset. The Microsoft Windows ISO doesn't have the native USB 3.0 drivers either, and that is why USB Keyboard and mouse will not respond. So you have to add the USB 3.0 drivers into the Windows ISO.

The solution is same as posted earlier

This time I have used latest ISO images of Windows 7 & 2008.
