CG, now I am in a bigger trouble. After the suggestion to follow post 129 made by Terry, the last result is that I can't access anymore my VISTA: Iget, at boot, error 14:... (I don't remember the full explanation). I added in HNS an entry for WIN 2000 marking it as XP but if I boot it I get a microsoft error about missing win..\sytem32\hal.dll, if I remember well. Now I am in XP (disk D:\). Is there a procedure to restore my system as before installing HNS, before doing other trials? About that error You are asking for, I saw it in a window like that giving the previous error (I think a debugger) before You corrected the language problem. Please help me!
