But this causes my computer to start the operating system specified as target upon next start. Also after turn my computer off and start it again later. This will keep me in one operating system whenever I start my computer - or am I wrong? I'm going to test it - now. I will post a report here. Edit Report: That's it: Using this I will have the same effect on using "Neu starten" and "Ausschalten". There's no diffrence between "Neu starten" and "Ausschalten". I'm reaching the same operating system but I want to XP on "Neu starten" the Bootmanager on "Ausschalten". Is there actually a way?
