Previously I outlined how to install Ubuntu over the network using a netboot install CD or USB image. This tutorial takes it a step further and allows you to boot your machine from the network environment and select from a list of what you would like to install. This comes to the same end result as the previous tutorial (an installed machine without having to burn a CD), but doesn’t require the boot CD or USB image.
This will take more work and should also be considered intermediate to advanced. Please read through the tutorial in its entirety before diving in, researching any aspects of the tutorial you’re not familiar with prior to attempting these steps.
