VistaBootPRO is a free software to make changes to the Windows Vista Boot Configuration Data (BCD) registry quickly and easily. The only other way to edit the BCD is to use the command prompt application “bcdedit.exe,” located in the Windows\system32 folder of Windows Vista but which requires additional knowledge about the switches and options of bcdedit.exe and is not easy for novices. VistaBootPRO does this through a GUI.

Note: It is highly encouraged that all user’s make a backup of the BCD store using the backup option in VistaBootPRO 2.1 Beta BEFORE making any changes to the BCD entries.
