To burn an iso image, see https://help.ubuntu.com/community/BurningIsoHowto

To write the USB image to a flash drive, run:

sudo zcat ubuntu-remix-804.usb.gz >/dev/sdxX

where "sdxX" is the correct device (sdc1) for example. Be careful to pick the correct device as writing this to disk will erase everything else on the disk.

If the device does not boot, try installing an MBR onto the USB drive:

sudo apt-get install mbr

sudo mbr-install /dev/sdX # Pick the correct device!
