Mac won't boot properly after putting in Windows 7 boot disc
I wanted to get Windows 7 on my Mac, so I got the disc, ran boot camp assistant, and when it said install Windows 7, I put the disc in, and clicked continue. The Mac reset, and after it got past the white screen, it went black, and my keyboard and mouse stopped working. Now I can't take the disc out because it won't let me go to my desktop.
Mac Pro, Mac OS X (10.7.5)
