I have a 20" iMac 2.0Ghz Intel Core Duo and I just went to boot into windows to play a game and then tried booting back into mac and it won't allow me. I'll click on the grey mac icon on windows and select restart in mac os x and it says it can't locate the disk. I try to select the disk in bootcamp under windows control panel and it says I don't have permission(will not load bootcamp just gives a popup message) I then tried restarting and holding options down to select which drive I want to boot into and it won't allow me to do this either. It keeps loading windows. I even tried putting my leopard dvd in the drive and it still loads windows. Any ideas how to get around this?
