Thanks to the guys over at Pro networks for this:
Designed for both beginners and advanced users, VistaBootPRO can be used to make "cosmetic" changes to the Windows Vista boot Menu such as changing the name of the Operating Systems shown in the boot menu and make advanced "functional" changes like adding an Operating System to the boot menu and repairing the Windows Vista boot configuration data. Advanced settings include backing up and exporting your boot loader configuration and modifying various details for the entries.
*The Vista boot loader (installs with Vista, not removed by formatting)
*Windows 2k, 2k Server, XP, 2003 Server, Vista, or Longhorn Server
*.NET 2.0 Framework (included with Vista, for other OSes it is available free from Microsoft.com)
VistaBootPRO is the ultimate boot editor and runs on a wide variety of systems and platforms: you donít even need to run it from Vista!
