well i installed windows and created a partiotion was a second install cause i figured this softwqare i was going to try out would crash the system. so i used parted magic to delete the second partition i had made with the windows and all and am now back on the first partition however on the startup screen theres still to options to boot win10 and win10 one has been compleatly erased but not that part of it. how do i fix this
