GRUB loader not shown - Dual boot Windows 10 and Kali linux 2016.2

If the installation of Kali was successful (no errors / automatically reboot) try to check your BIOS.
In Dell notebook you have to add the EFI-entry manual an change the boot order to:
1. Kali-Linux
2. Windows-Boot-Manager

Hey thanks for your answer. Already checked the BIOS settings.

Edit your 1st command as mount /dev/sda2 /mnt and try them again.

_defalt i have a problem:
Used terminal in Kali Life mode.
Tried your tip with /dev/sda2

Now i launched:
mount /dev/sda2 /mnt
-> worked fine

But at the command:
mount --bind /dev /mnt/dev
There came the error:
mount: mount point /mnt/dev does not exist

Because the first time, as i used this commands, it worked at this point i tried to create the dirs manually with mkdir /mnt/dev
The same for /mnt/proc , /mnt/sys

After that, all these commands worked:

mount /dev/sda2 /mnt
mount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys

But at chroot /mnt the error:
chroot: failed to run command ‘/bin/bash’: No such file or directory
appeared.

Do you have any idea?
