Thanks to all for the help I have had in the past. My latest difficult is: I use windows xp pro on an AMD 3200+ 64. I have one internal HDD and two external HDD's. I would now like to install windows 98 se on to one of the external drives. 98 se read me states that I must install it first if I want to use both systems. Does anyone know of a way I can install 98 se on an external disk drive without it messing up xp on my internal drive? Any advice gratefully accepted. Regards, LionJon.
