Dual boot Win2K and SuSE 7.3 Pro

I am dual booting my laptop between SuSE 7.3 Pro and Win2K, when I boot Linux it all works fine, but when I restart it and choose Win2K from my startup options (I am using System Commander) my laptop goes to the starting windows screen with the percentage bar along the bottom, it gets about 75% of the way across the screen and then it stops. The little scrolling graphic that keeps running left to right during this time is still scrolling, but I left the computer go for about 15 minutes with no drive activity and it never comes up. If I then shut down and restart again it goes right into Win2K without a problem. Anyone have any ideas on what would cause this type of problem? Greg Hicks
