Make a directory for the mount point and give it read-write permissions
chmod a+rw /mnt/C
Then edit the /etc/fstab file and add the following
/dev/sda1 /mnt/C ntfs-3g defaults,users,noexec,umask=000 0 0
Change /dev/sda1 to whatever the windows partition is (you can find it by doing fdisk -l
and looking for the partition that says NTFS). Then you can just type mount /mnt/C
Some of the above commands might need to be run as the root user or using sudo
. If you google for your distribution name and ntfs you'll probably come up with a step by step guide pretty quickly.
