How do I create a bootable USB drive for Ubuntu?

Addendum:  If you want to install to a USB flash drive, that can in fact be done -- but it takes special, mystical jiggery-pokery to avoid boot time issues with grub and how it recognizes drives and passes that information to the kernel.  It's not difficult, just tedious, and an already-running linux system is needed to make the necessary changes on the target USB flash drive.

you make bootable Flash Drive with the help of tool Universal-USB-Installer. you can download from below site:
