First unplug everything from the pc (nothing inside) and wait at least 15 min to kill all the built up charges Then start it and go into bios and see if what your UEFI options are and try around with them If that don't work look up the boot settings and start from the ssd if that don't work start it with win 10 cd from the bios (I can't see the vid). If that don't work I might be able to help you with some riskier ways but they should be a last resort cuz it could damage your data.
