Multiboot USB (Pendrivelinux)

Attempting to create a Multiboot USB (Pendrivelinnux - http://www.pendrivelinux.com/boot-multiple-iso-from-usb-multiboot-usb/) to contain the emergency boot iso.

Anyone have experience with this?

I'm assuming the lines would be similar to:

# Acronis Backup & Restore
title Acronis Backup & Restore
find --set-root --ignore-floppies --ignore-cd /acronisboot.iso
map /acronisboot.iso (hd32)
map --hook
chainloader (hd32)

Also, just a side note, attempting to add HDDErase to this configuration too. I just created a directory with the name hdderase and extracted the files into that directory. But off topic to what my original question is.
