Glad I could help.
I looked at the EasyBCD utility that you posted a link to. Unfortunately, I don't think it will help, because it looks like EasyBCD can only be used to modify active bootloader. In other words, you have to run it on a Vista installation. (There is a way to run it on XP, but that involves actually replacing XP bootloader with Vista's, so that's not the way to go).
You will need a utility that can open a BCD file. The mentioned methods of using bcdedit.exe or regedit are the ones I know of. If you can find another utility that can edit a BCD file, then it would be good to know as well.
