Far as I am being told by the owner, this unit came with win7 but he upgraded to win8 and now wants to revert back to win7 after he started getting this error message on boot up: "Error: No boot disk has been detected or the disk has failed". So I am attempting to reload win7 now but seems the wireless mouse which came with it is not working, only the wireless KB works. I just tried a wired KB and that works too but not a wired mouse which I need to make the selection to install windows, it's not the USB slots because the KB's work in both slots.
I just loaded Knoppix, the mouse works fine in knoppix so I am lost here, any ideas please?
