Well, most of the guides here illustrate sid 4--so I decided to give it a shot. The problem for me was once I set up everything by the guide it would not let me access my dual boot stock M$ giving me a message saying it doesn't exist (I know it does because I uninstalled the mod and everything worked fine). I didn't have this trouble with Sid 5.01--but I am and was a little worried about this version since the set up steps differ from sid 4. For example using HD C or virtual drive etc instead of just selecting open tray/unleash x. So in a nutshell here are my two questions; Is there a good guide illustrating how to set up SID 5.01 and as far as SID 4 is concerned what could the problem be with it not wanting to recognize the dual M$ side?
