No Mouse Movement Booting into Secondary SSD

[Mikestum]

And the problems continue....

I recently installed a new SSD with Windows 10. I am trying to boot into my old Windows 7 SSD to uninstall programs but once I get to the sign in screen to select the account I want to use on the Win 7 SSD I cannot get the mouse to function. I have tried:

A wireless mouse, a USB wired mouse and a PS2 Mouse. No luck....

Any suggestions on how to get this working OR are there any ways to uninstall programs from the Windows 7 SSD through the Windows 10 SSD?

Thanks everyone!

Your best bet at this point is to get in touch with ASRock tech support (generally speaking they're reasonably responsive in our experience) re this issue/problem.
The Z170 motherboards had serious compatibility problems with Win 7 particularly with mouse/keyboard issues as well as other issues. See, for example, http://www.asrock.com/microsite/Win7Install/

I haven't worked with any Z270 board yet but it seems clear that these compatibility problems involving Win 7 will continue - if not reach a point where booting to and working within a Win 7 environment will be near-impossible. Perhaps not, but it seems that's the direction.

We've been working in a multi-boot environment (with an ASRock Z170 board) where Win 7 & Win 10 are installed on the same drive so that Win 10 provides a "boot menu" during the bootup allowing the user to select either OS.
