Greetings,
I'm at a friend's house visiting and doing a lot of tech work for their computer/laptops. At present, I have a laptop that used to belong to his dad that was given to his is son. I guess he tried to reformat or something, so he could start from scratch, but now he has 2 installations of win7 on it. when the laptop starts there is a bios like screen where i am given the choice to choose from win7 or win7. His son is 12 and i really don't want him to have to worry about this, how can i remove or uninstall just 1 of these?
