Ubuntu

 
 
Ubuntu is a popular Linux distribution (Debian-based), with Unity as its default desktop environment. Development of Ubuntu is led by Canonical Ltd a company based on the Isle of Man and owned by South African entrepreneur Mark Shuttleworth.

The official name of an Ubuntu release is "Ubuntu X.YY" with X representing the year (minus 2000) and YY representing the month of eventual release within in that year.

Every six months a new desktop and server version is released. With the Long Term Support (LTS) version you get three years support on the desktop, and five years on the server. Upgrades to new versions of Ubuntu are free of charge.

Information
This tutorial describes how to install Ubuntu 14.04 from an USB stick (8GB) on a Dell Optiplex GX260 small mini-tower where Microsoft Windows XP is installed. Ubuntu will replace the Microsoft Windows XP as this operating system will not be supported by Microsoft as of April 8, 2014. Support and updates for Windows XP are no longer available and poses a huge security risk if you continue to use it.

The Dell Optiplex GX260 small mini-tower, used in this tutorial, has the following specifictations: WARNING:

Procedure
  1. Make sure your computer can boot from an USB device

    By default the Dell Optiplex GX260 can not boot from an USB flash device.
    To make this possible you need to make the following changes:

    • Make sure the Dell Optiplex GX260 has the latest bios version installed: Dell OptiPlex System BIOS, A09

    • If bios version A09 is installed, insert an USB stick on the backside of the computer and start the computer.
      Press the F12 button to enter the Boot menu.

    Type: md5sum ubuntu-14.04-desktop-i386.iso
    You should see: c4d4d037d7d0a05e8f526d18aa25fb5e

    Note:
    If you have installed Cygwin on your windows environment you may already have md5sum.exe installed.
