I've been experimenting with Windows Longhorn, and Whistler, on real hardware and I've mostly been able to get Longhorn to work. The only problem is that on boot it says to choose an OS, either Longhorn or XP, and both of them go to Longhorn since I installed it over XP. How can I remove the XP prompt from boot so I don't have to press enter every time I do a restart or startup?
