Hi - My HP Envy laptop developed a ghost administrator after last update. I am unable to make any changes without the password which I did not create so I want to clean install Windows 10. I purchased the USB Windows 10 Pro version but I seem unable to change the boot order in bios as there is a blue arrow which always points to the OS drive for boot up despite me changing the order. When I boot up and F9 it shows the USB which I choose and then it just goes to a black screen with a blinking minus cursor.
