Install a second OS or manage your boot configuration without directly editing the BCDEdit file.

VistaBootPRO was developed to make changes to the Windows Vista Boot Configuration Data (BCD) registry quickly and easily, doing the job in a fraction of the time it would take using the alternative. VistaBootPRO allows users to easily and neatly organize their boot configuration entries from within all flavors of Windows.
