I have windows 10 and ubuntu-16.04 installed in dual boot.

I want to get into the Linux universe from time to time and I have a problem that is rather intriguing to me! When I installed, Ubuntu already has Windows 10 installed with two C: and D: partitions.

To install Ubuntu I created a third partition with on the hard disk and installed ubuntu in dual boot! Until then, everything OK !!

When I opened the Ubuntu OS I can see the disks C: and D: and I can read and write files on them !! But after using the system two or three times, do not know the right, is no longer allowed to read or write the disks through Ubuntu!

What happened?

    What error(s) are given?. I speculate this may be your issue, or it is has been corrupted somehow.

If the NTFS drives are mounting as read-only, its probably because Ubuntu thinks their filesystems are unclean, probably due to hibernation, or a damaged file system. Do this...

in Windows...

  • boot into Windows
  • open the Power control panel
  • choose change what the power buttons do
  • choose change options that are unavailable
  • uncheck fast startup
  • close the Power control panel
  • open an administrative command prompt window
  • type powercfg /h off
  • type chkdsk /f c:
  • approve to run chkdsk at next reboot
  • type chkdsk /f d:
  • reboot into Windows to let chkdsk run on drive C:

    Wasn't me, but I could imagine it is because a 5.5 k user probably knows the essence of this answer by heart, since it was posted tons of times.

    ^ If I search for "unclean" on AU, I get no less then 280(!) posts, of which most are posted on exactly the same cause as this question. Anyone who has been longer on the site than a week must have seen several on them, because it has been asked over and over again. Then answering the question instead of linking to one of the many dupes is a bit faint imo. No offense btw.

    Hello, I know you want to help people but the better way would not involve duplicating answers. Consider voting to close the question as a duplicate. It may take a little more time but it will be more beneficial in the long run.

    @heynnema Actually, it IS our collective responsibilty to locate and flag duplicates That being said, this is likely better discussed on meta
