TypeID

Updated: August 1, 2012

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

Use TypeID to manually specify a hard-drive partition type, such as a utility partition type.

  • Five partition types are already built in: primary, extensible firmware interface (EFI), extended, logical, and Microsoft® Reserved (MSR). To use these built-in partition types, enter a value in the setting: Microsoft-Windows-Setup/DiskConfiguration/Disk/CreatePartitions/CreatePartition/Type.

  • Some partition types are not assigned a drive letter by default. Without a drive letter, these partitions do not appear in some common lists of devices, such as in Windows® Explorer or in Open or Save file dialog boxes. If you assign a letter to the partition, the partition appears in these common lists of devices.

 

TypeID

Specifies the partition type. See the Partition Types section later in this topic.

TypeID is a string.

The following XML output for the DiskConfiguration setting shows partition modifications that set the recovery partition with the utility partition type. This partition does not appear with a drive letter in Windows.


      <ModifyPartition wcm:action="add">
        <Order>1</Order> 
        <PartitionID>1</PartitionID> 
        <Label>WinRE Tools</Label>
