My Dell Mini 12 screen says Operating system not found.How do I fix it?

First try holding the control key and scroll down. If it doesn't work, then it's probably a resolution problem. First, try replugging the wires from the monitor to computer.

If it doesn't work, check the Display menu in System Preferences to make sure a lower resolution hasn’t been selected.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
