replace Y & X to where your ntfs partition is
where i have /home/USER/WIN put where you want to mount the partition
then go to that directory & create a folder with that name on mine i like to have easy access to it so i put it in my home
by default other distros would put it under /mnt/win(1,2,3,or c,d,e)
after that i would reboot to make sure all is well & correct
