Installation • Can't chroot into "mnt" to reinstall Grub

Well I got right up to the point where I "chroot" into ${ROOTFS} /bin/bash and get hit with the "no such file or directory. And unlike the previous error messages, I was not able to mkdir the directory to chroot into. Here is my inuputs. I am so aggravated.
