Hello, I am trying to install Windows 7 Ultimate onto my Mac Mini using Boot Camp Assistant. On the Windows 7 install it reboots three times. On the third time, it boots to black screen with "Press any key to boot from CD or DVD...." When I try to hit any key on my Apple Wireless Keyboard, it does nothing. Same thing when I hook up a wired USB HP keyboard to the mini. It is entirely unresponsive. I have tried letting it run for a while to see if it would move on. I have tried changing the startup disk in Mac OS X to the Windows partition but I get nothing but a blank black screen with a flashing underscore. Does anyone have any ideas? I have tried googling but I have found nothing (so far). And yes, for God's sake, I have pressed ANY KEY. I have pressed every freakin key on both the keyboards, no luck. Thank you for your help.
