Hello, i'm new to the site. Was hoping someone here could help. I've had Boot Camp on my iMac for a while now, but just last night and still today every time I boot to windows, right after I select the user it restarts the whole computer back to OSX. I have no idea whats going on or how to fix it. Also, everytime I start windows my bluetooth keyboard has to be turned off then back on and reconnected, but only for windows. Is there something i'm missing so I can avoid having to do this?
