I have tried several times to upgrade a Windows 7 desktop (i5, 8 GB RAM, 2 x 1TB drives in RAID 0) to Windows 10 but on first reboot it asks me to choose a keyboard layout and then only gives options "Troubleshoot" or "Turn off your PC". After restarting it allows me to log into Windows 7 and then shows the message below in a popup. I have tried uninstalling the network driver as suggested on another site, I've unplugged all hardware except for keyboard and mouse. I've tried the upgrade from a flash drive and have also tried mounting the ISO and launching from that. I've ran CHKDSK and found no errors, I've ran sfc /scannow and found nothing wrong. I've tried using Windows 10 version 1809, 1909, and now 2004.
