This is not a correct installation procedure. Please follow the instructions at:

Now you're maintaining two versions of Gromacs, which in itself is not a
problem, as long as your environment is configured correctly, but you have to be
careful in setting that up. I don't have an explanation as to why no commands
are working, but you may have to re-configure your environment to only recognize
one Gromacs installation at a time.
If you no longer need an old version, you can simply remove it.
