Getting Ubuntu CDs
There are several ways to get Ubuntu install CDs.
Downloading CD images can be found at http://www.ubuntulinux.org/download/ If you have broadband this is a quick option.
Buy CDs Search the web for "cheap linux cds" May cost a few dollars per cd, usually quick to arrive.
You could also have a look at forum/GiveAway for people who are offering to send out ubuntu CDs
Burning the Install/Live CD
If you have downloaded the CD you will need to write it to a CD-R. Have a look at the BurningIsoHowto
The Install CD won't boot
Check that you burned the CD correctly, see the BurningIsoHowto
If you are using a PC check that your BIOS is set to boot from cd. Some older machines may not be able to boot from CD, these will need a boot floppy (see How To Make A GRUB Boot Floppy )
If you are using an Apple Mac, hold down the 'C' key
The download may have been corrupted, try checking the md5sum, or re-downloading. Note: can someone write a HowToMD5SUM
Sometimes disabling acpi is needed for the install to work.
From the installer's boot prompt, enter
More disabling things to make stuff work

eg Card: Sapphire ATI Radeon x800 GTO PCI-E
In a terminal type
sudo apt-get install xorg-driver-fglrx sudo aticonfig --initial sudo aticonfig --overlay-type=Xv
fresh install has weird networking problems
From personal experience with Debian and ubuntu Breezy and Dapper it is advisable to disconnect any networking ethernet cables.
While this could be isolated cases, the effects experienced of ethernet cable on fresh install are
1)ati grapics card not configured and install either hangs or you get text login as xserver-xorg not configured.
2)can access web with browser, but synaptic claims it can't down load known working repositories.
3)packages that would normally be installed damaged or missing.
[BUG]By pinging google.com using network tools, suddenly synaptic and other aplications can access internet
