My co worker is trying to dual boot windows vista on his imac. He ran into a problem with the install code. While he is trying to verify that his code is correct, can't get the windows vista disk out of his machine. What he has told me is when the windows instilation asked for the correct instal code he gets the option to input the correct code or restart the computer. in an attempt to abort the instalation he chose restart. Instead of being able to get to the osx desktop, he is thrown right back to windows loading the instilation files where it prompts for the password. because I too am a new windows convert, I don't know how to help him get his imac to boot back to osx so he can drag the disk image icon to the trash to get the disk out of his machine.
