I cannot upgrade my laptop from windows 7 to windows 10 as when I install it, after the 2-3rd restart (around 10% done) my external monitor turns off and turns on my laptop screen which is broken. after this I cannot continue with the install as i cant see the screen. i have tried leaving it with the screen on to see if its the drivers. This didnt work. I have tried with both VGA and HDMI. As the year free upgrade is coming to an end i want to upgrade beofre it costs.
