Ok ... I still don't understand what you want to do
a) If you want to boot from your USB Memory Stick - That means that the contents of your memory stick is Linux. You do not necessarily need to have Linux installed in your computer, for everything will be read from your USB stick.
If this is your situation ... check this:

Note that you will need:
- USB Memory Stick
- A computer that can actually boot from USB
- Some really small Linux distro.
b) If you want to boot from a CD- ROM and use your USB Stick for storage - That means you don't have Linux installed in your computer, and you want to insert a CD and load Linux. Your USB stick will store all your information.
Note that you will need:
- USB Stick
- A computer that will boot from CD-ROM
- A Live Linux Distribution (MandrakeMove, e.g.)
c) If you want to boot from your hard disk drive and just use your USB stick to store information. In this case, any distribution will be useful for you
You just need to get into a console as root and type
mount -t vfat /dev/sda1 /mnt/stick
(provided /mnt/stick actually exists
)
Please give information about what you want. (What you plan to use your USB stick for, or something). Maybe we can guide you any further
