[kwlug-disc] question -- booting from multiple ISOs in USB stick?

[William Park]

Hi all,

Right now, I'm carrying around 2 USB sticks,
    - one 32GB -- it boots Linux and contains about 10 bootable ISOs.
    - one 8GB -- to 'dd' the real ISO that I want to boot.

It's 2-step process, and it's ok.  But, I would like to reduce it to
1-step.

How can I boot those multiple ISOs directly from one USB stick?
