I realize this question is almost two years old, but I answer it for those who find this in search and need the answer.
First, mount your Windows partition as read-only. If your Windows partition is the first partition on your first hard drive add this to the file
/dev/sda1 /mnt/windows ntfs ro,umask=0222,defaults 0 0
You have to create a directory called windows first.
If you want to mount the partition after boot and not be logged in as root, use this:
/dev/sda1 /mnt/windows ntfs user,ro,umask=0222,defaults 0 0
To mount a specific Windows directory as read and write, use
fuse-ntfs-3g. Most people will want to mount their Documents, so I will use this use example. If you are user David on Windows and david on Linux, use this (substituting
ntfs-3g or whatever current kernel module you have installed):
/mnt/windows/Users/David/Documents /home/David/Documents ntfs-3g rbind,user,umask=0222,defaults 0 0
rbind is what remounts an already location to another. For a more detailed explanation of other options in the comma separated list, type info
ntfs-3g in a command console. The Documents directory in Linux must exist and should be empty. This line must be after the line that mounts the Windows partition.
This is for Windows Vista and 7. If you have Windows XP, use
/mnt/windows/"Documents and Settings"/David/Documents. The quotations are important because mount cannot accept spaces in the directory name even though Linux has no problems with spaces in directories.
If you don't have a kernel module that can mount NTFS as read and write, you need to install one.
Ubuntu comes with
ntfsconfig. Any currently connected partition should be automatically detected and set up to be mounted automatically. Ubuntu also mounts nonnative partitions like Windows under
/media instead, usually with the name of the operating system, so your Windows 7 partition is mounted at
/media/Windows 7. You will find your
fstab entry uses unicode strings for special characters so that the line says
\040 is substituted for the space without the need for quotes.
To mount David's Windows 7 documents in david's Linux home directory in Ubuntu, put this in
/media/Windows\0407/Users/David/Documents /home/David/Documents ntfs-3g rbind,nosuid,user,umask=0222 0 0
I hope this helps.
