In computing, bootcfg is a command on Microsoft Windows NT-based operating systems which acts as a wrapper for editing the boot.ini file. Overview The command is used to configure, query, or change Boot.ini file settings. A similar command exists in the Recovery Console for repairing or rebuilding boot configuration files. Though NTLDR and boot.ini are no longer used to boot Windows Vista and later versions of Windows NT, they ship with the bootcfg utility regardless. This is to handle boot.ini in the case that a multi-boot configuration with previous versions of Windows exists and needs troubleshooting from within the later operating system. Windows Vista and later versions will warn users who run bootcfg that BCDEdit is the correct command to modify its booting options. Syntax The command-syntax is: bootcfg <parameter> [arguments...] Parameters addsw – Add operating system load options copy – Make a copy of an existing boot entry dbg1394 – Configures 1394 port debugging debug – Add or changes debug settings default – Specify the default operating system entry delete – Deletes an operating system entry ems – Add or change settings for redirection of the Emergency Management Services console query – Query and displays [boot loader] and [operating systems] section entries raw – Add operating system load options rmsw – Remove operating system load options timeout – Change operating system time-out value References Further reading External links bootcfg | Microsoft Docs Windows administration Windows commands
