Specifying a GPT disk configuration

This wizard window allows you to define the UEFI configuration of the disk on which the operating system will be installed. A number of disk configurations are predefined for these cases and are made available. They are ready for use with all of the deployment types for UEFI installations.

1. Select the desired disk configuration for the project.

2. Click Next to go to the following wizard page.

   Be careful not to select a disk configuration that will format the drive or partition for a WIM Image Capture .

The following topics describe the operations performed on GPT Disk Configuration:

• • Creating a new disk configuration
  • Creating a disk configuration
  • Modifying a partition

Creating a new disk configuration

If none of the predefined disk configurations answer the requirements of your distribution you can create a new disk configuration. Creating new disk configurations consists of the following two steps:

1. Create a new disk configuration

2. Create partitions for the new configuration

   Note:

   Be aware that WinPE has a number of limitation as described on the Microsoft website (http://technet.microsoft.com/en-us/library/cc507857.aspx) such as the fact that drive letter assignments are not persistent between sessions. This means that no matter which drive you assigned specific drive letter in the disk configuration of an OS deployment, the drive letter assignments will be in the default order after WinPE is restarted.

Creating a disk configuration

To create a new disk configuration proceed as follows:

1. Select OS Deployment > Your OSD Manager > Disk Configuration in the left window pane.
2. Select Edit > Create Disk Configuration .

3. Enter the necessary data for the parameters in the Create a New Disk window:

   Parameters	Description
   Name	A descriptive name of the object.
   Description	This is a free text field into which you can enter any type of description and information that is pertinent to the new disk configuration.
   Size (GB)	The size of the disk. It is only used to estimate if the partitions overall size is sensible. It has no impact on the real disk.
   Delete Disk Partitions	Defines if any partitions that already exist on the target device are deleted. This option should be used with caution, as any data on the disk is lost irretrievably if selected.
   Partition Type	The type of the partition if formatting the partition. Operating systems should be installed on primary partitions.
   Disk Number	The physical disk number on the device, 0 indicating the first disk, 1 the second, etc.
   Status	Before the disk configuration can be created it must be verified that all entered data is correct. To execute a check on the disk click Test next to the non-editable Status box. Be aware that the disk creation cannot be confirmed until the disk verification succeeded, that is, the status value OK is displayed.
   Notes	This free text field can contain additional information concerning the selected object.

4. Click OK to confirm the data for the new disk configuration.

The new disk configuration with the specified data is created.
