White screen on iMac 2011 27"
I have a big problem.
First of all, i know there are many of these threads about this problem, but i not manage to find a solution for me.
I have a iMac 27" mid 2011. Everything works fine, until i tried to install Bootcamp.
The installation went fine, and i could boot in Windows.
There was some Windows updates i will install, and Windows ask for reboot.
After that reboot, my iMac comes with only a white screen. and nothing else. And altso the chord sound.
I trid reset PRAM, and, COMMAND+S, D, Command+SHIFT+R+P and so on.
Is anyone have an idea?
