Extend specifies whether a newly-created primary partition is extended to fill the remainder of the hard disk.

Values

true

Specifies that the newly-created primary partition is extended to fill the remainder of the disk.

false

Specifies that the newly-created partition is a fixed size, as specified by CreatePartition:Size. This is the default value.

When creating a new partition, you must either use CreatePartition:Size, or set CreatePartition:Extend to true.

Note

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.

XML Example

The following XML output for the DiskConfiguration setting shows how to create two partitions on a hard drive. The first partition has a fixed size of 100 megabytes (MB). The second partition is extended to fill the remainder of the hard disk.

<DiskConfiguration>

  <Disk wcm:action="add">
    <DiskID>0</DiskID> 
    <WillWipeDisk>true</WillWipeDisk> 
    <CreatePartitions>

      <!-- System partition -->
      <CreatePartition wcm:action="add">
        <Order>1</Order> 
        <Type>Primary</Type> 
        <Size>300</Size> 
      </CreatePartition>

      <!-- Windows partition -->
      <CreatePartition wcm:action="add">
        <Order>2</Order> 
        <Type>Primary</Type> 
        <Extend>true</Extend> 
      </CreatePartition>

    </CreatePartitions>
    <ModifyPartitions>

      <!-- System partition -->
      <ModifyPartition wcm:action="add">

        <PartitionID>1</PartitionID> 
        <Label>System</Label> 
        <Format>NTFS</Format> 
        <Active>true</Active> 
      </ModifyPartition>

      <!-- Windows partition -->
      <ModifyPartition wcm:action="add">
        <Order>2</Order> 
        <PartitionID>2</PartitionID> 
        <Label>Windows</Label> 
        <Letter>C</Letter> 
        <Format>NTFS</Format> 
      </ModifyPartition>
    </ModifyPartitions>
