Boot to selected ISO on USB

I want to boot to a selected ISO USB stick but also store data there.  I have a variety of ISOs that I need to boot to on a regular basis.  Currently, I've never successfully booted to a USB stick to begin with so my experience is limited.  Assistance is greatly appreciated.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
