Extend

  • Artigo

Applies To: Windows 7, Windows 8, Windows 8.1, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Vista

Extend can be used to modify existing partitions. You can use Extend on BIOS/MBR-based systems to:

  • Specify a new or existing logical partition to fill the remainder of an extended partition.

  • Specify a partition within an existing partition structure to fill the remainder of the disk.

Note

UEFI/GPT-based disks do not support the Extend setting.

Values

true

Specifies that the selected partition is extended to fill the remainder of the disk.

false

Specifies that the selected partition is not extended to fill the remainder of the disk. This is the default value.

  • To use extended and logical partitions

    To create a logical partition that uses the remainder of the extended partition through Windows Setup, create a partition that has an initial fixed size. For example: CreatePartition:Size=100. Then, modify the partition by setting ModifyPartition:Extend=true.Do not set both CreatePartition:Extend and ModifyPartition:Extend to true. For more information, see How to Configure More Than Four Partitions on a BIOS-Based Hard Disk.

  • To modify a partition within an existing partition structure to extend to the remainder of the disk

    Set ModifyPartitions:Extend to true.

  • To specify a newly-created partition to fill the remainder of the hard disk

    Set CreatePartitions:Extend to true, and leave ModifyPartitions:Extend empty.

XML Example

Specify a Logical Partition to Fill the Remainder of an Extended Partition

The following XML output for the DiskConfiguration setting shows partition modifications for a BIOS-based computer with two logical partitions. This XML example includes the creation of an extended partition that is set to extend to the end of the hard disk. The second logical partition, labeled Logical2, is set to extend to the end of the extended partition. The following illustration shows these partitions.

Specifying an Existing Partition to Fill the Remainder of the Hard Drive

The following XML output for the DiskConfiguration setting shows how to modify an existing hard drive partition structure. In this example, the third partition is extended to fill the remainder of the drive.

<DiskConfiguration>
   <WillShowUI>OnError</WillShowUI>
   <Disk>
      <DiskID>0</DiskID>
      <WillWipeDisk>false</WillWipeDisk>

      <ModifyPartitions>

         <!-- Modify the existing Windows partition -->
         <ModifyPartition>
            <Order>1</Order>
            <PartitionID>3</PartitionID>
            <Format>NTFS</Format>
            <Extend>true</Extend>
