dual-bootable USB with 32-bit XP and 64-bit Win7

How would one create a flash drive that, when set as boot device, immediately displays a menu that lets you choose to boot from either 64-bit Win7, or 32-bit Win XP? If this is not possible, then maybe another menu is possible: XP Recovery Console for 32-bit systems, and Win7 for 64-bit systems.

I'm more interested in such a tool for troubleshooting systems that won't boot, as opposed to using it to install either of these OS's.....don't want to carry around two USB sticks if I don't have to.

I write the Win7 installer to stick using UltraISO Software To Create Bootable USB Flash Drive.

When it completes you'll notice that the installer's folders are in the stick root, where they can co-exist with other tools and program apps, as I've done for years with a 16gb Kingston Data Traveler.

To boot another bit version or Vista/Win8, you only need to put the extant installer folders away in their own storage folder and extract the desired installer folders into the stick - which is already permanent bootsected by UltraISO to boot an nt60 installer until it is wiped with Diskpart Clean Command.

Keep each OS/Bit version installer folders in a separate folder on or off the stick.

This lacks the boot menu so is a manual method but it's always worked so well for me that I haven't gone looking for anything more which requires a boot loader.

If you only need the Repair disk ISO's those can be written to stick using Win2Flash.

Greg, thanks for your helpful answer!! I hope before long to pay it back to someone else on this forum!!!
Cheers,

You're most welcome, Jeff, and especially with that spirit!
