I have installed Vista and XP on my system.
Every OS is working fine.
I can start Vista or XP as often as I want without problem.
But as soon I change from one system to the other I get a black screen after I have chosen the OS in the bootloader menue and the laptop starts again. Then I chose the same OS again and the display shows "normal start" or Help. If I chose normal start the OS starts fine.
So at the end I always need two starts to get in the other OS and one start if select the same OS as before.
