MacBook Pro: Bootcamp Windows 7 Ultimate – Mouse – Keyboard lock-up
I’ve been running Microsoft Windows 7 Ultimate on my MacBook Pro Late 2013 for at least 4 months. I’ve installed many applications on it, and had absolutely no issues. One day I went to boot it up and my mouse/keyboard would not function. I was stuck on the login/password (Windows 7 screen). I thought it was a fluke, I rebooted and same exact issue. I tried safe mode, and encountered same problem. I then attached a usb keyboard and mouse….still nothing. I was baffled. Nothing worked. I tried booting with PE, custom O/S’s that I have compiled, and still same issue. It didn’t make sense.
After messing around with it (on and off) for a few hours. I found a temporary solution. When you are about to boot into Windows 7 click F8. This will give you an advance boot up menu. And select the very last option “Disable Driver Signature Enforcement”.
My mouse and keyboard functioned once again. Here’s the fun Windows part, I can’t permanently disable Driver Signature Enforcement. By default it will not let you override it (at least I haven’t figured out a way to do so). OK, whats next? Well sign the drivers that need signing. However, I’m unsure what drivers are causing this as I haven’t installed any new unassigned drivers. I installed the latest version of bootcamp to see if that would fix it, however I’m back to F8.
Who is to blame? Microsoft? Apple? Or both….I’m going with both this time around.
Hope this helps someone who is stuck on a frozen Windows 7 username/password screen.
