Sample: Configure More than Four Partitions on a BIOS/MBR-Based Hard Disk by using Windows Setup

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

You can add answer file settings to automatically configure disk partitions during Windows® installation. This topic shows how to configure disk partitions for a BIOS-based computer that has more than four partitions, as described in Configure More than Four Partitions on a BIOS/MBR-Based Hard Disk.

This sample configuration includes three primary partitions and an extended partition. The primary partitions include two utility partitions and a system partition. The extended partition includes two logical partitions. These include the Windows partition and a recovery image partition. The following diagram shows this configuration:

To extend the last logical partition in an extended partition by Using Windows Setup

To create a logical partition that uses the rest of the extended partition through Windows Setup, create a partition that has an initial fixed size, and then modify the partition. For example, set CreatePartition: Size=100, and then set ModifyPartition: Extend=true.

Microsoft-Windows-Setup\DiskConfiguration\Disk	DiskID = 0 WillWipeDisk = true
Microsoft-Windows-Setup\DiskConfiguration\Disk\ CreatePartitions\CreatePartition	Order = 1 Size = Size of Utility1 in megabytes; for example, 100 Type = Primary
Microsoft-Windows-Setup\DiskConfiguration\Disk\ CreatePartitions\CreatePartition	Order = 2 Size = Size of Utility2 in megabytes; for example, 200 Type = Primary
Microsoft-Windows-Setup\DiskConfiguration\Disk\ CreatePartitions\CreatePartition	Order = 3 Size = 350 Type = Primary
Microsoft-Windows-Setup\DiskConfiguration\Disk\ CreatePartitions\CreatePartition	Extend = true Order = 4 Type = Extended
Microsoft-Windows-Setup\DiskConfiguration\Disk\ CreatePartitions\CreatePartition	Order = 5 Size = 75000 Type = Logical
Microsoft-Windows-Setup\DiskConfiguration\Disk\ CreatePartitions\CreatePartition	Order = 6 Size = 100 (this will be changed in the ModifyPartition section) Type = Logical
Microsoft-Windows-Setup\DiskConfiguration\Disk\ ModifyPartitions\ModifyPartition	Format = NTFS Label = Utility1 Order = 1 PartitionID = 1 TypeID = 0x27
Microsoft-Windows-Setup\DiskConfiguration\Disk\ ModifyPartitions\ModifyPartition	Format = NTFS Label = Utility2 Order = 2 PartitionID = 2 TypeID = 0x27
Microsoft-Windows-Setup\DiskConfiguration\Disk\ ModifyPartitions\ModifyPartition	Active = true Format = NTFS Label = System Order = 3 PartitionID = 3
Microsoft-Windows-Setup\DiskConfiguration\Disk\ ModifyPartitions\ModifyPartition	Format = NTFS Label = Windows Order = 4 PartitionID = 4
Microsoft-Windows-Setup\DiskConfiguration\Disk\ ModifyPartitions\ModifyPartition	Format = NTFS Extend = true (this overrides the CreatePartition:Size value) Label = Recovery image Order = 5 PartitionID = 5
Microsoft-Windows-Setup\ImageInstall\OSImage\InstallTo	DiskID = 0 PartitionID = 4 TypeID = 0x27
