Ubuntu – Is it possible to create an installation disk of Ubuntu, from an already existing installation?

Use existing Ubuntu partition as an installation image?

I'm using Ubuntu 11.10, and wondering if it is possible to create an installation disk/image from my existing installation.

I need to install it on my friend's PC. I'm just wondering, can it be done, or do I have to download the whole installation again?

If any are wondering why I would bother to do this, it is just because
Internet speed here isn't any good, monthly quota is pretty low, and
the prices are even worse.

Installation instructions quoted from remastersys forum.

The Synaptic Method:

  1. In Firefox, go to:

    http://www.remastersys.com/ubuntu/remastersys.gpg.key save file as text someplace where you can find it.

  2. In synaptic, go to Settings/Repositories; select "Authentication" tab and "Import Key File" just downloaded.

  3. Still in synaptic, go to "Other Software" tab and click "Add", then enter the apt line and replace oneiric with either lucid, maverick, or natty to match your Ubuntu version:

    deb http://www.remastersys.com/ubuntu oneiric main

  4. Leave the repositories tab and "Reload".

  5. Search for "remastersys" and select for install. Edit/Apply Marked Changes.

The Manual Method

Download and apply the repository signing key.

wget -O - http://www.remastersys.com/ubuntu/remastersys.gpg.key | sudo apt-key add -

Add the following line to your /etc/apt/sources.list, substituting "oneiric" for your Ubuntu version (e.g. lucid, natty, maverick)

deb http://www.remastersys.com/ubuntu oneiric main

Now just sudo apt-get update or reload in Synaptic to have the new Remastersys signed repository ready to use!
