So I installed Windows on a 20g partition on my macbook today, after the install, it booted to windows fine...realizing it never installed any boot camp stuff. So I am in windows now without a way to use wifi, or boot back to OSX. So I loaded up the OSX cd, and booted from that. Opened Disk Utility, and removed the partition and resized OSX to use the whole disk and restarted w/o cd. now it just hangs on a black screen, how do i get my OSX back!!?? Thank you very much for any help.
