I'm having trouble installing GRUB bootloader manually. I was attempting to install Kali Linux to dual boot with my already existing Windows 10 system. During the installation, it said it couldn't install GRUB, so I tried to manually install it from a Kali Live USB. However, whenever I run these commands in Terminal:

mount /dev/sda5 /mnt
mount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt
grub-install /dev/sda

It says bash: grub-install: command not foundgrub-install: command not found. grub2-install also doesn't work. Trying update-grub says the same thing. GRUB was never installed, so how do I install it? Thanks!
