Upgraded a plain vanilla version of Vista SP1 on my Thinkpad X61t and after finishing copying all the files it rebooted as Windows 7 and then asked me for the activation code. The problem is that the mouse cursor is stuck in the top left corner and the keyboard doesn't respond! If I try to reboot through safe mode (even command prompt) it always tells me that I have to finish the seutp first, displaying a single button (Which I cannot of course click). What on earth can I do? Can I remove the installation? But how?
