This computer's hardware may not support booting on this disk. Windows cannot be installed on this disk. When I got to choose where to install Windows, there was an error message: I started the computer from the OS install flash made with the Microsoft flash installer as downloaded and created from Microsoft. I thought It should have a CMOS BIOS problem, so I removed the battery for one minute to reset, put it back and it started as usually. The keyboard diodes flickered once a little after pressing the start button (as they usually do), but nothing else happened, not even the fans worked. Before installing I turned the PC off and disconnected the other disks (please refer to my system, a bit oldish and home assembled) I wanted to install it on a SATA disk. So I decided to Clean the disk, format it and make a fresh installation. My OS had too many issues since I upgraded fromWin 7, installing Win 10 on top.
