When you run update-grub from sda5 it reads the /boot/grub/grub.cfg from sda9 which was copied from sda5. First boot into sda5 which is your primary OS. Then use these commands to fix:
SourceUUID=cc3bca0d-aee4-4b9c-95c2-57212cc36d4d
TargetUUID=64662470-0e58-4dfd-90ac-43227d773556
sudo mkdir /mnt/clone
sudo mount -t auto -v /dev/sda9 /mnt/clone
sudo sed -i "s/$SourceUUID/$TargetUUID/g" /mnt/clone/boot/grub/grub.cfg
sudo update-grub
sudo umount /mnt/clone -l
I based this answer on a Ubuntu 16.04 LTS clone to new partition script.
