Easy BCD

I used Easy BCD to dual boot Vista 64 (Primary OS) and add XP. Now I need to do the reverse, remove XP , and use that space to add a second new install of Vista 64. (I don't want to lose the original) Is that possible?

I'd like to do this as the orig install of vista 64 has gone flaky; MS tech support has sent me in a circle but did not resolve the problem (lost Control Panel and no access to printer and can't reinstall it).

Maybe this can be done with Easy BCD, but I can't figure out how to do it.
