Download the ISO image from the Ubuntu download page and burn it to a blank CD. There are different images you can install, depending on whether you are running a desktop or server or processor you have installed (i.e., Intel x86, PowerPC, or AMD64). For most home computers, you can install the PC desktop version since it supports most machines.
Turn on your computer and insert the newly created Ubuntu CD. On some computers, you may need to press F2 or Esc during the BIOS startup so that it will boot from the CD-ROM drive instead of the hard drive.
Once you see the Ubuntu menu, select Start or install Ubuntu and press Enter. Ubuntu will then start up the X window. When you see the Ubuntu Desktop, double-click on the Install icon.
When you see the Welcome window screen, click the Forward button. If you don”t see the Cancel or Forward button on your screen, press Alt-F7. The cursor should change from an arrow to a hand. You can now move the Welcome screen with your mouse. Move the Welcome screen up a little until you can see the Cancel or Forward button. Specify the appropriate language and click the Forward button.
When you see the time zone screen, specify your time zone and click the Forward button.
When you see the keyboard layout screen, specify your keyboard and click the Forward button.
When you are prompted to create a user account, specify an account that will be used as the administrator so that you can log in to your computer. You can create more users after the installation. You are also prompted to create the computer name of your computer. Click the Forward button.
When you are prompted to partition the disk, specify to Manually edit the partition table and click the Forward button. How you partition your disk is a personal choice and depends on the purpose of the computer.
For example, if you have a 200GB hard drive, you can create a separate swap partition (e.g., 2GB), a separate / root partition (e.g., 20GB), and the remaining partition for the /home partition (e.g.,178GB). With this configuration, you can reinstall the whole system without moving your personal data to another location. Once again, your disk configuration may vary depending on your preference. Click the Forward button.
When you are prompted for the mount points, select the partitions you specified earlier. For example, 2GB for the swap partition, 20GB for the / root partition, and 178GB for the /home partition. Click the Forward button.
When you are prompted to verify the disk configuration, click the Install button. The installation program will now start to install the operating system.
When the installation has completed, click the Install Now button to restart your computer. Remove your Ubuntu CD when prompted.
