So, I just got my new Mac Book Pro, my first Mac. I decided to install Windows 7 and went ahead and partitioned the HD, hit Install and only then realized that I had left a disc in the disc drive. Now my Mac is looking for a bootable disc and I can't put one in. Jeez, I hope I'm not the first person to make this mistake. Any suggestions on how to remove the disc or restart the machine with OS X? Thanks,,,,,
