Letter (Standard 8 Module Reference)

7/8/2014

Review the applicable Embedded Core modules and any examples for the Letter setting in Windows Embedded 8 Standard (Standard 8).

This setting contains an uppercase letter between C and Z that specifies a drive letter to assign to the partition.

Do not create an empty value for this setting. If you do not specify a letter, the default value is the first available letter from C through Z.

The following table shows whether the system assigns drive letters to various partition types.

System type	Partition type	Assigned a drive letter by default?
BIOS/MBR	Windows data partition	Yes Note: System partitions do not receive a drive letter.
BIOS/MBR	System partition.	No
BIOS/MBR	Recovery or utility partition	No
BIOS/MBR	OEM partition	No
UEFI/GPT	System partition.	No
UEFI/GPT	Microsoft Reserved partition	No
UEFI/GPT	Windows data partition	Yes
UEFI/GPT	Utility partition	Yes

Modules

The following table shows the modules that you can apply this setting to. In Image Configuration Editor (ICE), you can follow the corresponding path to set this setting for a module.

Module	Path
Setup	Products/Embedded Core/Setup/DiskConfiguration/Disk/ModifyPartitions/ModifyPartition/Letter

XML Example

The following example for the DiskConfiguration setting shows two partition modifications. The System and Recovery partitions are not assigned a letter. The Windows Embedded partition receives the drive letter C. The data partition receives the first available drive letter between D and Z, depending on what other drives and hardware are present on the computer.

<ModifyPartitions>
    <!-- Windows Embedded partition -->


    <ModifyPartition wcm:action="add">
        <Order>3</Order> 
        <PartitionID>3</PartitionID> 
        <Label>Windows</Label> 
        <Letter>C</Letter> 
        <Format>NTFS</Format> 
    </ModifyPartition>

    <!-- Data partition -->
    <ModifyPartition wcm:action="add">
        <Order>4</Order> 
        <PartitionID>4</PartitionID> 
        <Label>Data</Label> 
        <Format>NTFS</Format> 
    </ModifyPartition>
</ModifyPartitions>
