Just delete the tree and remove its path from the PATH variable. If
you made symlinks, you have to remove the symlinks. But wait, first
you should understand why the installation failed otherwise you will
be at the very same situation after installation from DVD. if you
really do not remember what you set as the installation path and you
do not have PATH properly set, you can find it by the "find" program.
On my computer the output is:

$ find / -name article.cls 2>/dev/null

You can see that I have OS/2 version of emTeX, OS/2 version of teTeX,
TL subversion working copy, TeX distribution from the Linux distro and
7 versions of TeX Live. If I wanted to uninstall the latest TeX Live,
I would do it by:

rm -rf /usr/local/texlive/2013

The executable directory for me is /usr/local/texlive/2013/bin/x86_64
because I have 64bit Linux computer. You should find that directory
and look what is inside it.

Having found it reinstallation even over a slow net should be faster
than a new installation from a DVD if you run the network installer
and install to the same path. If I remember it well, the installer
will download missing or updated packages only.

Remember that no matter what the installation media is, you always
have to understand how to set PATH, otherwise TL will not work. If you
did ot manage to do it after network install, you will not be able to
do it after DVD install. And remember that the ISO image is old, since
its creation a great many packages have been updated. You will have to
use your slow net to update them. On the contrary the network
installer installs the latest version. Thus your tree from the network
installation is newer than what you have on the DVD. You will be
wasting both time and bandwidth if you install from DVD instead of
understanding what happend with your network install.
