This is the software publisher’s description.

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. Included in this latest release are additional features, including a built-in help file and more advanced boot configuration options.

For those who have had to use the command prompt based bcdedit.exe in the past, you will be impressed with the ease of use and functionality that VistaBootPRO provides.

Note that Windows Vista is still a beta operating system, so future changes to the operating system may make VistaBootPRO function incorrectly. Check back for future updates when new editions of Vista are released. Preliminary testing indicates it is compatible with Vista Release Candidate.
