I upgraded Win 8.1 Pro 64bit to Win 10 Pro 64bit through the app process.
I am periodically ( 2-3 times a day) getting a black stop screen with 'Error 1962: No Operating system found'
I have a Lenovo IdeaCentre 12 GB ram, I7 quad, huge C: with 1,5tb left on it.
ctrl+alt+delete reboots it so I can logon again.
Does anyone have an idea about that?
