usb - multiboot

[keithc]

im sure there are numerous posts about how to acheive this, however all the posts ive read seem rather complex and im just a simple lazy techie

basically, i want to setup 4 partitions on my usb key, 1 for xp pro, 1 for 2k pro, 1 for winternals ERD 2005 and 1 for storage, the other requirement i have is a menu upon booting from the usb to select the appropriate OS.

i have looked at the 'easyboot' program by the same developer as ultra iso however its not as straight forward as it appears.

if anyone can provide a definitive step by step guide on how to acheive this, it'd be much appreciated.
