Create Multi-Bootable USB disk for installation Win Xp, Windows 7 and Windows Server 2008

Hi I need install Windows Xp, Windows 7 and Windows Server 2003 from one USB flash stick.

I google it and I found some tools such as WinSetupFromUSB but I would like have all type windows on one usb stick.

if I use for example WinSetupFromUSB I must have 3 USB stick, one for XP, second for Win 7 and third for Win Server 2003.

It is possible?

Your Universal Multiboot Installer will do this. From their page:

YUMI (Your Universal Multiboot Installer), is the successor to MultibootISOs. It can be used to create a Multiboot USB Flash Drive containing multiple operating systems, antivirus utilities, disc cloning, diagnostic tools, and more. Contrary to MultiBootISO's which used grub to boot ISO files directly from USB, YUMI uses syslinux to boot extracted distributions stored on the USB device, and reverts to using grub to Boot Multiple ISO files from USB, if necessary.
Aside from a few distributions, all files are stored within the Multiboot folder, making for a nicely organized Multiboot Drive that can still be used for other storage purposes.

All you need are ISO files for each OS.

for 7 and better, use the official dvd/usb download tool. The steps here would work for vista if that didn't. Not sure about xp - this seems to be the only other method that you haven't tried mentioned, using pe2usb
