Howto create bootable usb-stick without an ubuntu installation?

[Clemens Eisserer]

Hi,

I would like to install kubuntu on my laptop which doesn't have a
working CD drive.

I found a tutorial in the wiki which explains creating a bootable usb
stick using a program called "usb-creator", however its not available
on fedora, and is also missing on the lubuntu live-cd.

Is there a manual way to create a live usb stick?

Thank you in advance, Clemens
