/set |
Sets an entry option value. |
Parameters that Control Output |
Parameter |
Description |
/enum |
Lists entries in a store. The /enum option is the default value for BCEdit, so running the bcdedit command without parameters is equivalent to running the bcdedit /enum active command. |
/v |
Verbose mode. Usually, any well-known entry identifiers are represented by their friendly shorthand form. Specifying /v as a command-line option displays all identifiers in full. Running the bcdedit /v command by itself is equivalent to running the bcdedit /enum active /v command. |
Parameters that Control the Boot Manager |
Parameter |
Description |
/bootsequence |
Specifies a one-time display order to be used for the next boot. This command is similar to the /displayorder option, except that it is used only the next time the computer starts. Afterwards, the computer reverts to the original display order. |
/default |
Specifies the default entry that the boot manager selects when the timeout expires. |
/displayorder |
Specifies the display order that the boot manager uses when displaying boot parameters to a user. |
/timeout |
Specifies the time to wait, in seconds, before the boot manager selects the default entry. |
/toolsdisplayorder |
Specifies the display order for the boot manager to use when displaying the Tools menu. |
Parameters that Control Emergency Management Services |
Parameter |
Description |
/bootems |
Enables or disables Emergency Management Services (EMS) for the specified entry. |
/ems |
Enables or disables EMS for the specified operating system boot entry. |
/emssettings |
Sets the global EMS settings for the computer. /emssettings does not enable or disable EMS for any particular boot entry. |
Parameters that Control Debugging |
Parameter |
Description |
/bootdebug |
Enables or disables the boot debugger for a specified boot entry. Although this command works for any boot entry, it is effective only for boot applications. |
/dbgsettings |
Specifies or displays the global debugger settings for the system. This command does not enable or disable the kernel debugger; use the /debug option for that purpose. To set an individual global debugger setting, use the bcdedit /set <dbgsettings> <type> <value> command. |
/debug |
Enables or disables the kernel debugger for a specified boot entry. |
<dbgsettings> <type> <value> |
