It's strange, I know I definately have not deleted it. In fact I can open Windows using Parallels and it works fine. The image says 'My Boot Camp.pvs' However I cannot close Leopard and boot into Windows. The disc image has compeltely disapppeared. When I click on 'Startup Disk, all that is there is 'Mac OS X, 10.5.4 on Macintosh HD' and an image 'Network Startup' That is all If I restart the machine then it just OS X boots up. I am not given a choice, even I hold down the option key. Any advice would be appreciated. Thanks.
