Boot Configuration Data Store Editor (BCDEdit) is the primary tool for editing the boot configuration of Windows 2008 Server. Boot Configuration Data Store Editor (BCDEdit) is a command-line tool for managing BCD stores. BCDEdit can be used creating new stores, modifying existing stores, adding boot menu parameters etc. The Boot Configuration Data Store Editor (BCDEdit) command is a powerful replacement for the
BootCfg utilit, which was available with previous versions of Windows.
To get general help of BCDEdit from command-line, run BCDEdit with /? option.
