Why can't Ubuntu mount NTFS when Windows is completely shut down?

Question

NTFS

There are two operating systems: Windows 10 and Ubuntu 16.04, on different logical drives, there is also NTFS for storing media data. After running Windows for a long time, the PC turns off in the usual way, that is, through Start until it stops completely. But it's worth booting from Ubuntu the next time I turn it on, I get an error:

The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully...

The error information says that Window is not completely shut down, so you can't mount the drive for writing, even though it's completely shut down. The error does not appear after booting under Windows, and immediately turning it off (that is, in the period of time after it was loaded and turned off, no extraneous software was launched).
What could be the reason for this and how to solve this problem without downloading a new one to Windows every time before booting to Ubuntu?

Answer 1

In fact, this happens, as a rule, when Windows is shut down correctly - it, in fact, does not turn off, but goes into hibernation by the kernel, starting from either version 8 or version 7.
You can disable this in Windows, or you can try to fix it from Linux (riskily!)
ntfsfix /dev/sdX

Answer 2

You have incorrectly shutdown Windows and it is marked on ntfs. ntfs-3g had some kind of force mount flag for such cases, if you want to take risks, and do not want to correctly extinguish Windows.
