HOW to CHROOT and install Grub in ExTiX while using Refracta Installer on non UEFI computers (for example VirtualBox and VMware) 

Copy and paste the commands below.

sudo su
mkdir /mnt/sda1
mount /dev/sda1 /mnt/sda1 (i.e. mount the install partition)
mount -t proc proc /mnt/sda1/proc
mount -o bind /sys /mnt/sda1/sys 
mount --bind /dev /mnt/sda1/dev
chroot /mnt/sda1 /bin/bash (i.e. "chroot" into the install partition) 
apt update
apt install grub-pc
grub-install /dev/sda
update-grub

exit
umount /mnt/sda1/proc 
umount /mnt/sda1/sys
umount /mnt/sda1/dev
umount /mnt/sda1

NOTE: You shall of course change /dev/sda1 to suit your installation partition

Watch a screenshot when I run the commands above - http://debex.exton.net/debex-kde/debex-kde-chroot-grub-install-vbox-200228.jpg

As you can see the screenshot is for DebEX, but it's valid for ExTiX too.
