I have basically the same problem as Rydoge except mine happened after trying to upgrade an old machine. I resurrected the machine & got it working with its WIN 7 OS then used the option found at https://www.theverge.com/2016/8/1/12340318/microsoft-windows-10-free-upgrade-still-available to try to move to WIN 10. After an overnight download/install, I was presented with the 'Welcome to Windows 10' screen. I clicked 'Next' but was presented with the same error message that Rydoge received. When I closed that message, the computer went into a reboot/back to 'Welcome' screen/error message loop.
Should I go the Media Creation Tool route & boot from a USB?
Is there a way for me to boot back to WIN 7? ... assuming it still exists
