I'm not sure what distro you're using or what editors you have available to you, but basically, you need to edit the file /etc/fstab as the root user. First, unmount the partition using your graphical tool.
I typically use a command line for editing; type su
(then enter root's password) -- this will make you root (BE VERY CAREFUL). You'll need to find out what drive has windows on it by typing fdisk -l
(that's -L, not -1). Make note of the partition that says "NTFS", it should be something like /dev/hda1 or /dev/sda1.
Make a backup of the fstab file -- cp /etc/fstab /etc/fstab.orig
To edit the fstab file, type nano /etc/fstab
which should give you a pretty easy command line editor. The commands at the bottom like ^X mean press CTRL+X. Use your arrow keys to navigate.
Your file should look something like this:
/dev/hda2 / ext3 defaults 1 1
/dev/hda3 /swap swap defaults 0 0
/dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0
You want to add a line like this:
/dev/hda1 /media/windows ntfs user,nls=utf8,umask=0222 0 0
Change /dev/hda1 to whatever your windows partition is and/or change /media/windows to whatever directory you want to mount the NTFS partition (some people prefer to put it in the /mnt directory, like /mnt/windows). Then save the file and type mount -a
, which should remount all filesystems. Then you should be able to go to whatever directory you put in fstab for the mount point and read any files on the partition.
