There are tons of howtos on the web for creating live USB sticks for Ubuntu. Almost all of them start with "First, download the CD image and burn it to a CD. Now, boot off the CD and ..."
The few that don't discuss apps like usb-creator-gtk or unetbootin tha work great if you're burning the current Ubuntu Live CD image from a reasonably current Ubuntu machine, but which fail miserably in every other case (wildly pathological cases like burning the current Ubuntu alternate installer CD from the last long-term-support version of Ubuntu. I mean, really, should that be so unusual?)
Tonight, I wanted a bootable USB of Fedora 12. I tried the Ubuntu tools already mentioned, but usb-creator-gtk won't even try with an image that isn't Ubuntu, and unetbootin wrote something but the resulting stick didn't boot.
I asked on the Fedora IRC channel, where a helpful person pointed me to this paragraph on copying an ISO image with dd.
Holy mackerel! One command:
dd if=Fedora-12-i686-Live.iso of=/dev/sdf bs=8Mand in less than ten minutes it was ready. And it booted just fine!
Really, Ubuntu, you should take a look at Fedora now and then. For machines that are new enough, USB boot is much faster and easier than CD burning -- so give people an easy way to get a bootable USB version of your operating system. Or they might give up and try a distro that does make it easy.
