So recently I was trying to factory reset my PC because there was a few problems. When I tried to do it I let it go and it kept going up in percentage but when I came back it was just a black screen. So I power off and then powrr up my PC. It comes to this page that says An operating system wasn't found. Try disconnecting any drives that dont contain an operating system. Press Ctrl alt Del to restart. Please help. BTW windows was preinstalled and I dont have disk for windows 10. It boots up on a ssd
