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?
