@Terio Boot PC. When its starting, press F12 or Del or another key (the BIOS key, varies from PC to PC)
Then go to boot options, switch boot order so 1st one is the name of your USB, where u have OS.
Save settings, reboot pC, format, and after that go back to BIOS and switch to the harddrive you have your OS installed. GG WP good luck too!
