How do I create an administrator account during automatic repair (Windows 10)?

I've had a problem on my laptop for weeks, I've tried everything to get out of the automatic repair, but it's no good as I have to log in as an administrator to get further. Neither can I reset and it repeats itself again and again when restarting. The only one of the setting options with which I can start is with (UEFI firmware settings)

Try to start the computer in safe mode (you have to google it, something different for someone's laptop). Then try to delete it

I was in the start settings to activate the mode with key 4, it started again with the same screen (automatic repair is being prepared) Does anyone know about the UEFI firmware settings to create an administrator?
