how do I download it

Thanks Dines683, that solved my question.

how do I get a burning application?

please help me

If you are using Ubuntu you dint need a burning application separately.Its defaultly installed in your Ubuntu.

Just go to

Places --> CD/DVD Creator

Copy and past required files to be written and click BURN.

This will make your need.

I can't find Places --> CD/DVD Creator

I can't find Places --> CD/DVD Creator

Alright, heres another way to do it if you already have Ubuntu installed.

Download the .iso image to your desktop, right-click it and select ¨write to disk¨ this will do everything for you, although you might want to reduce the write speed to lessen the chance of errors on your burn.

Places should be in the top left, between applications and system. unless you have some freaky desktop layout I´ve never seen before, thats where it usually is.

If youŕe not running Ubuntu already, first off I´d like to say I feel bad for you, but we can fix that. =)

just download the .iso image of Ubuntu 8.04 from here http://www.ubuntu.com/getubuntu/download

open your CD burning application, and burn the .iso file to the disk. again slower speeds mean more reliable writes, but generally you shouldn´t have any problems. I just slow it down because I´m really paranoid and hate wasting hours of my time. Restart computer with disk in drive. Install ubuntu. You´re all set.

Hope that helped.
