Is It Possible to Install Ubuntu Through Network?

You can install one Ubuntu system (typically an Ubuntu Server system, but it does not have to be), and then use it as a server to PXE boot and install the others. The BIOSes on the clients (where you want to install Ubuntu) must support PXE (i.e., network boot) for this to work. But most BIOSes do, these days.

You should be able to do it with a non-Ubuntu system as the host, too, if you already have that set up and you know how to configure the necessary servers on your non-Ubuntu system.

The PXEInstallServer Ubuntu help wiki article explains how to set up an Ubuntu system as your PXE server, and how to install Ubuntu on other systems from it. It would be hard to summarize the main points--the details are very important. So here's the whole thing (with minor formatting and punctuation changes):

Introduction

This will guide you through running an Ubuntu server as PXE install server. You'll need to run a DHCP server on your network, not necessarily this server but you do need one.
