If you are running Windows 10 on multibooting περιβάλλοντα (πολλαπλής εκmovements), you should disable the fast startup feature.
The so called "Fast Boot” ήρθε για πρώτη φορά με τα Windows 8. Στόχος του είναι να μειώσει το χρόνο που απαιτείται για την εκκίνηση του συστήματος. Κατά τη διακοπή λειτουργίας τα Windows χρησιμοποιούν ένα trick για να επιταχύνουν την επόμενη εκκίνηση. 
Before shutting down, Windows 8.1 - 10 terminates all applications running in the background and closes the user session. But the Windows kernel does not stop, as in Windows 7. From Windows 8 onwards, the operating system writes parts of RAM with the kernel image to a file when it shuts down.
So at the next boot, the state of the stored system (memory image, state of dwork) is read from hibernation file (hiberfil.sys) and restart the necessary drivers.
The advantage of this approach is that when you use the state hibernation(hibernation mode), much less data is backed up than in Windows 7 hibernation mode (in Windows 7, memory images are also backed up to the hibernation file). So on boot, the system is ready to work again much faster than with a conventional boot.
Problems with multiboot
However, there are drawbacks to a quick boot, especially in multiboot environments with Windows 10. Fast Boot will present you with many problems when other operating systems are installed on your PC. Especially if you have a fast computer with SSD / NvME in Windows 10, you should seriously consider disabling fast boot.
The hiberfil.sys hibernation file simply becomes huge by storing the kernel image on machines with a lot of RAM. Then, loading this file takes longer than it takes to boot the operating system and load the kernel.
Also, when restarting to change operating system, the process is slowed down by a quick boot. In fact, if the system you want to boot is Linux then you will have problems with the file system.
The shutdown in Windows 10 does not shut down the computer completely
