Hello, Last week I installed windows vista on my laptop, after restarting the pc, the pc shows windows vista 2 times. So the pc is saying, you installed windows vista 2 times, but i don't know how? One of the windows vista's is normally working, the other not. This is because its not activated, i used the activate key for the other vista. Now i want to uninstall or delete the not working vista, but how can i do this? is there someone who can tell me how to do this? You can compare the starting up screen with the picture below. I hope someone can help me.
