BCDEdit Operation on entry options

BCDEdit /deletevalue

image This command deletes a data element from an entry in the boot configuration data store.

Syntax

bcdedit [/store <filename>] /deletevalue [<id>] <datatype>

Parameter

<filename>Specifies the store to be used. If this option is not specified, the system store is used. For more information, run "bcdedit /? store". <id>Specifies the identifier of the entry that will be modified. If not specified, {current} is used. For more information about identifiers, run "bcdedit /? ID". <datatype>Specifies the option that will be removed from the specified entry. Run "bcdedit /? TYPES" for more information about data types.

Example

The following command deletes the bootsequence option from the boot manager entry: bcdedit /deletevalue {bootmgr} bootsequence The following command deletes the Windows Preinstallation Environment (WinPE) value from the current operating system boot entry: bcdedit /deletevalue winpe The following command deletes the Windows PE value from the specified operating system boot entry: bcdedit /deletevalue {cbd971bf-b7b8-4885-951a-fa03044f5d71} winpe

BCDEdit /set

image This command sets an entry option value in the boot configuration data store.

Syntax

bcdedit [/store <filename>] /set [{<id>}] <datatype> <value> [ /addfirst | /addlast | /remove ]

Parameter

<filename>Specifies the store to be used. If this option is not specified, the system store is used. For more information, run "bcdedit /? store". <id>Specifies the identifier of the entry to be modified. If not specified, {current} is used. For more information about identifiers, run "bcdedit /? ID". <datatype>Specifies the option data type that will be created or modified. Run "bcdedit /? TYPES" for more information about data types. <value>Specifies the value that should be assigned to the option. The format of <value> depends on the data type specified. Run "bcdedit /? FORMATS" for more information about data formats. /addfirstThis switch can only be used if datatype is an object list. Adds the specified entry identifier to the top of the list. If this switch is specified, only a single entry identifier may be specified. If the specified identifier is already in the list, it will be moved to the top of the list. /addlastThis switch can only be used if datatype is an object list. Adds the specified entry identifier to the end of the list. If this switch is specified, only a single entry identifier may be specified. If the specified identifier is already in the list, it is moved to the end of the list. /removeThis switch can only be used if datatype is an object list. Removes the specified entry identifier from the list. If this switch is specified, only a single entry identifier may be specified. If the identifier is not in the list then the operation has no effect. If the last entry is being removed, then the datatype value is deleted.

Example

The following command sets the application device to the partition C: for the specified operating system entry: bcdedit /set {cbd971bf-b7b8-4885-951a-fa03044f5d71} device partition=C: The following command deletes the Windows Preinstallation Environment (WinPE) value from the current operating system boot entry: bcdedit /deletevalue winpe The following command deletes the Windows PE value from the specified operating system boot entry: bcdedit /deletevalue {cbd971bf-b7b8-4885-951a-fa03044f5d71} winpe NOTE: Use 'hd_partiton=' syntax to explicitly disable automatic VHD detection, and create entries that are compatible for booting a virtual machine, i.e., bcdedit /store F:\boot\bcd /set {default} device hd_partition=F: The following command sets the OS device to a VHD file (C:\vdisks\vdisk01.vhd) for the specified operating system entry: bcdedit /set {cbd971bf-b7b8-4885-951a-fa03044f5d71} osdevice vhd=[C:]\vdisks\disk01.vhd The following command sets the application path to \windows\system32\winload.exe for the specified operating system entry: bcdedit /set {cbd971bf-b7b8-4885-951a-fa03044f5d71} path \windows\system32\winload.exe The following command sets the NX policy to OptIn for the current operating system boot entry. bcdedit /set nx optin
