From my dual booted system I'm not able to write and edit the files in the hard disk partition which was created in Windows. I have checked the permissions but it looks to be fine. I can only read the files from that partition from Ubuntu but not able to edit and change it. Can anyone help me out regarding this issue?

Sample output of ls -ln ls -ln /path/to/file of non-writable file

Output of cat /proc/mounts

It's a read-only file system. Even if you have write permissions, it won't work, as the file system is mounted read-only. Maybe the file system is in an unclean state? It used to be that it refused to mount automatically, suggesting manually mounting read-only. Maybe that changed.

Boot Windows and run filesystem checks on the ntfs partitions. Make sure you shutdown Windows completely, unmounting all file systems. Linux can't mount ntfs partitions if Windows is (semi-)hibernated. Have a look here https://ubuntuforums.org/showthread.php?t=2342159

For changing permission of folders including its enclosed file. See this Question How can I change permissions of a folder, including its enclosed files and subdirectories?

  • Your situation looks a bit weird.Is your system showing any message or anything else when you are trying to make changes.

  • Check the permissions in properties of your disk both in Windows and Ubuntu.Try to copy or delete files using sudo command in terminal.

  • Actually now i found out that the permission of enclosed files in the partition was read only. But when i try to change those permissions it shows setting permissions and then terminates without changing the permissions and also without any warning

Check if you're running Windows 8 or higher. If that's the case, you need to disable Fast Startup (or some similar name, as they call it).
