Hi all, I just partitioned my iMac drive via Boot Camp. I successfully installed Windows 7 on that partition. But now my iMac only boots into Windows 7. I read a bunch of threads here and tried holding down many keys whilst booting. Option key gave me a grey screen with a lock on it prompting a password. I entered the computer's admin password, and tried leaving it blank, but nothign happened. when I held down Ctril + Command + p + j I was asked to choose which OS I wanted to boot....well my only option is Windows 7! I check and see Windows 7 is on the partition though (90gb I allocated w/ Boot Camp) Did I somehow erase OSX? no idea how! Any solutions are appreciated Thank you!!!
