I'd like to create an Ubuntu 14.04.3 LTS install CD, that will partition a hard drive (I need 4 partitions), and install Ubuntu on 2 of them - a primary and a backup. I want the install to avoid using network connectivity. Haven't been able to find any hints about how to avoid the network conn. Would anyone have some pointers?
I don't think that 14.04 LTS install can be bundled in a CD. It's ISO is around 1 GB and most of the CDs cannot go beyond 650-700 MB.
I had an old desktop(2008) which cannot boot from USB or DVD so i burned an Lubuntu into a CD drive that can fit into a CD. Once i installed that then installed Unity/Gnome via apt-get. Later upgraded to Ubuntu Linux into that old desktop via network(as it was having wifi card that i added later).
In your case you can also burn the Ubuntu 12.04 ISO to a CD.
Other alternative is to use net installer - you can somehow get a wifi card for this machine if needed.
I know this is not the exact solution to your situation/problem but some work around based on my past experience.
