I was recently working on a project and needed to use Ubuntu for a coding segment. I replaced my Windows system with Ubuntu 18.04, but what I actually needed was on Ubuntu 16.04. I have the ISO on an external hard drive and I have been trying to install it in GRUB. To no avail, I have looked across many other forums and none relate to my current situation. Any help would be great.
Thanks.

You don't 'install' an ISO in grub. Grub is the Linux boot manager and loader and has nothing to do with ISOs. Its Windows equivalent is the Windows boot manager which is part of the System partition, and you wouldn't install an ISO in there.
What you should do is make a live Ubuntu 16.04 UFD from your downloaded ISO, by extracting the contents from it to the UFD. You can do this easily from 18.04. Then simply boot up from the UFD when it's done. If you have enough space you could make a few extra partitions on your HDD, and install 16.04 from the UFD onto there, or better still a separate HDD. From Grub you will then have the option to boot to 16.04 or 18.04.
Alternatively you can use a virtual machine for installing 16.04. But my experience was that Ubuntu doesn't work so well in a VM, with quite a few gremlins (eg wireless connectivity issues) occurring for no apparent reason.
