chroot  /mnt  /bin/bash
export PATH=/bin:/sbin:/usr/bin:/usr/sbin

But the boot partition is not mounted on /boot within the chroot;
try  ls /boot and see what you get
So mount the boot partition as soon as you chroot

You will then be able to run commands with your new system
You are mounting /boot as a partition; so to grub this will
appear as containing just the files within that partition

There is no directory boot in that partition.

The thing to do is set a symbolic link
In chrooted in do
cd /boot
ln  -s  .  boot

It now appears that your boot partition contains a boot
and a boot/grub; and you wil be able to run grub
