I have been running across the same issues. I can get 1 OS to boot (either XP, vista or 7), but not more than one at a time. My idea to proceed at this point is to attempt to create a multiboot disc and then copy to flash drive and possibly try an additional partition on the same drive if possible. I would really like to have a disc for an IT guy. You know, all OSs from XP-8 with Server additions and other useful utils. I will update with any progress.
