How To Create A Partition With Diskpart

Creating Disks and Volumes Using the DiskPart Command

The following examples show how to create basic and dynamic disks using the DiskPart command.

Example 1: Creating basic disks using the DiskPart command.

Select a disk, whether it is Raw or dynamic disk, and convert it to basic storage type.

X:\windows\system32\DR>diskpart

Display existing disks.

DISKPART>list disk

DISKPART>list volume

Create the boot and system volume on disk 0

list disk and volume command

DISKPART>select disk 0

(Optional) Convert to GPT style, if needed

DISKPART>convert gpt

Create basic volumes for the System and Boot volume.

Create System volume

DISKPART>create partition primary size=100

Create Boot volume

DISKPART>create partition primary

DISKPART> list volume

Mark system partition as active.

DISKPART>list partition

DISKPART>select partition 1

DISKPART>active

Check the status of the system volume.

DISKPART> detail partition.

Note: Use active command only for the system partition.

(Optional) Assign the volume a drive letter and format it.

DISKPART>list volume

DISKPART>select volume 2

DISKPART>assign letter=C

DISKPART>format quick

Example 2: Creating a System and a Boot dynamic volume using the DiskPart command.

Select a disk, whether it is Raw or Basic disk, and convert it to a dynamic storage type.

X:\windows\system32\DR>diskpart

Display existing disks.

DISKPART>list disk

DISKPART>list volume

Create the boot and system volume on disk 0.

list disk and volume command

DISKPART>select disk 0

(Optional) Convert to GPT style if needed.

DISKPART>convert gpt

DISKPART>convert dynamic

Create simple dynamic volumes for the System and Boot volume.

Create a system volume.

DISKPART>create volume simple size=100

Create a boot volume.

DISKPART> create volume simple

Display created volumes.

DISKPART> list volume

Prepare volume 0 as the system volume.

DISKPART>select volume 0

DISKPART>retain

Prepare volume 1 as the boot volume.

DISKPART>select volume 1

DISKPART>retain

DISKPART> select disk 0

(Optional) Mark the system partition as active.

Display partitions.

DISKPART>list partition

DISKPART>select partition 2

DISKPART>active

Check the status of the system volume.

DISKPART> detail partition

diskpart retain command

(Optional) Assign the volume to a drive letter and format it.
```
DISKPART>list volume          
```
```
DISKPART>select volume 1          
```
```
DISKPART>assign letter=C          
```
```
X:\windows\system32\DR>format C: /q          
```
Note: If you created a UEFI System partition, format it to a FAT32 file system before you can restore data. You do not need to run the retain command.

Example 3: Creating a non-system/boot disk volume using the DiskPart command.

Select disks and convert to a Dynamic storage type.

X:\windows\system32\DR>diskpart

Display current disks and volumes.

DISKPART>list disk

DISKPART>list volume

Convert each disk except Disk 0 to dynamic disks.

DISKPART>select disk 1

DISKPART>convert dynamic

DISKPART>select disk 2

DISKPART>convert dynamic

DISKPART>select disk 3

DISKPART>convert dynamic

Create RAID-5 volumes on each disk. Similarly, you can create simple, stripe, or other dynamic disk types.
```
create volume raid disk=1,2,3          
```

(Optional) Assign the volume to a drive letter and format it.

DISKPART>list volume

DISKPART>assign letter=E

X:\windows\system32\DR>format E: /q

Example 4: Creating UEFI system volume and boot volume

Select disks and convert to the GPT type.

X:\windows\system32\DR> diskpart

Display the existing disks.

DISKPART>list disk

DISKPART>select disk 0

To create UEFI partition, disks must be converted to GPT type first.

DISKPART>convert gpt

Create the UEFI System partition.

Create the UEFI partition.

DISKPART>create partition efi size=100

Create the MSR partition.

DISKPART> create partition msr size=128

Create the primary partition.

DISKPART> create partition primary

DISKPART>convert dynamic

DISKPART>list volume

DiskPart Command using the convert dynamic argument.

Retain the boot volume.

DISKPART>select volume 1

DISKPART>assign letter=C

DISKPART>retain

(Optional) Format the system volume to FAT32.
Prepare volume 2 as system volume.
```
DISKPART>select volume 2          
```
```
DISKPART>format fs=fat32 quick          
```
```
DISKPART>list partition          
```
Note: You only need to retain the boot volume. To restore data to the UEFI partition, the master server should be UEFI partitioned.

Example 5: Creating Mirrored system volume and boot volume.: The following steps describe how to create mirrored disks on UEFI volume. For more information about mirrored disk on UEFI volume refer to Microsoft document at this link: http://support.microsoft.com/kb/951985

Select disk 0 and create the primary UEFI boot/system volume.

DISKPART>list disk

DISKPART>select disk 0

DISKPART>convert gpt

DISKPART>create partition efi size=100

DISKPART> create partition msr size=128

DISKPART> create partition primary

DISKPART>convert dynamic

DISKPART>list volume

DISKPART>select volume 1

DISKPART>assign letter=C

Select disk 4 as the secondary disk to create boot/system volume.

DISKPART>list disk

DISKPART>select disk 4

DISKPART>convert gpt

DISKPART>list partition

(Optional, delete existing partition) Select partition 1 on disk 4, and then delete it with the override command.

DISKPART> Select partition 1

DISKPART> Delete partition override

DISKPART>create partition efi size=100

DISKPART> create partition msr size=128

DISKPART>list partition

DISKPART>convert dynamic

Establish a mirror from the boot volume to the secondary drive.

DISKPART>select volume C

DISKPART>add disk=4

DISKPART>retain

(Optional) Format the system volume with FAT32.

DISKPART>list volume

DISKPART> select volume 1

DISKPART> format fs=fat32 quick

DISKPART> select volume 2

DISKPART> format fs=fat32 quick

Note: Establish mirror on the boot volume and retain this volume. You can only restore one Master UEFI system partition.

For more information about the DiskPart command, refer to Microsoft documentation.
