"hmm how do you do the permission thing?"
Log in as root. Linux will not let you change permissions on a mount point. So first umount the partition:
Use the chmod command (see: man chmod). If you want to change the permissions to 777 the command is:
chmod 777 /mnt/Linux-To-Window
Then reboot and you should be OK, assuming that /etc/fstab is set up to allow users to use /mnt/Linux-To-Window.
Be prepared. Create a LifeBoat CD.
