One thought, do you have latest BIOS on motherboard? it might be a miscommunication between board and windows as to what devices are attached
one suggested fix is to try running the reset using the win 10 installer
download the
Windows 10 media creation tool and use it to make a win 10 installer on USB
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose reset this PC
choose keep files/settings (Files = library folders. Library folders = Documents, pictures, movies, music (the default folders that come with windows). Settings = logins and desktop)
PC will restart and hopefully not get stuck on the keyboard screen again.
Another option is use the win 10 installer to clean install win 10 (after backing up everything you want to keep on your boot hdd) as it should fix this as well
change boot order in BIOS so USB is first, hdd second
boot from installer
follow this guide:

when you reach the screen asking for licence, click "I don't have a key" and win 10 will continue to install and reactivate once finished
On the screen where you choose where to install win 10, if it gives you an error about GPT drives, delete all the partitions on the hdd and press next. If it still gives error, cancel out of the installer and restart PC and start installer again, it will accept next on that screen this time (some PC just need a restart here).
