# Run LiveUSB in live or persistent mode. You'll need the terminal after installation.
# Install as normal. You'll get an error about not being able to install the bootloader, ignore and continue, do not reboot.
# If you do reboot, just get back into live mode and continue.
# Replace the drive/partition numbers where necessary in the code below and run the following commands to install/update GRUB2

#sudo mount /dev/sdXY /mnt
sudo mount /dev/sdb1 /mnt

#sudo grub-install --root-directory=/mnt/ /dev/sdX
sudo grub-install --root-directory=/mnt/ /dev/sdb

sudo mount --bind /dev /mnt/dev
sudo mount --bind /sys /mnt/sys
sudo mount --bind /proc /mnt/proc

# ONLY DO THIS IF SEPARATE BOOT PARTITION (I didn't)
#sudo mount /dev/sdaX /mnt/boot

sudo chroot /mnt
sudo update-grub
exit

sudo umount /mnt/dev
sudo umount /mnt/sys
sudo umount /mnt/proc
#sudo umount /mnt/boot #Only if you mounted it earlier
sudo umount /mnt/
