So I start my PC from the DVD drive with a Windows 7 .ISO file, no problems so far. The message on the screen says “Windows is loading files … “, 0k so far. But, after this, no “Custom”, no “Upgrade” appears and there is no way to make any user input.
Instead, the Microsoft blue sky screen with the little bird and a narrow black frame around the screen is visible, no icons, no buttons, only mouse, but no context menu. I can only unplug my PC and start it again. When started normally the machine is working well – almost – except that Windows Update is damaged, hence wanting to do a clean re-install of Windows.
Help from Microsoft has failed me, and I will receive no more support from them.
