I don't know if this will help anyone but it sure worked for me. My desk top was caught in the round about screen with keyboard language selection and neither my USB mouse or keyboard were active. I downloaded from my laptop a file called Media creation Tool from Microsoft onto a USB flash drive. With a few questions and selections was able to complete the tool for another device. Put the USB drive into my stuck desktop and selected repair computer and then selected USB drive. Restarted desk top and couldn't get the BIOS screen. Shut computer down and unplugged AC power cable and plugged it back in. Restarted desk top and got the F10 prompt and selected the USB drive to boot first. Restarted desk top and booted thru the USB drive. Got to a window that said unplug USB drive and restart Windows normally. Just left the USB drive in place and restarted desktop normally. After a little while my Windows 10 and all applications loaded like normal. I ran a file check and a registry repair tool and corrected what errors they found, rebooted desk top and it was like brand new or like it was before being stuck with keyboard screen. I have saved the USB drive with the Media Creation Tool because I have had several problems with Windows 10 loading. I hope this helps people stuck in a repeat window and Windows 10 not loading. Worked like a charm for me. I was ready to do a complete new install and this returned me to my desk top with all applications working. Yee-Hah!
