How come my Grub isn't initialised at the boot?
I dual booted Kali next to Windows7 and after a succesfull install I rebooted to not find an option to use Kali instead of Win7 in the BIOS.
After having done some research I found out that Win7 has a tendency to uninstall GRUB.
So looking into that I rebooted using my live usb with kali on it and tried to solve my problem by trying to reinstall GRUB using the explanation here ,and adjusted the sda3 to sda6 since this is where I have kali installed on my harddrive:

I remove the live usb and reboot my computer while holding shift but it goes back to the windows bootloader.
Any idea on what I am doing wrong?

After reboot you need to update the grub to add WIndows partition (per your link):os-proberupdate-grubHave you done this already?

Ok ,that worked. Now I got this after having to sudo apt-get install grub: root@kali:~# update-grub Searching for GRUB installation directory ... No GRUB directory found. To create a template run 'mkdir /boot/grub' first. To install grub, install it manually or try the 'grub-install' command. ### Warning, grub-install is used to change your MBR. ###
