Working with Extended Partition and Logical Drive in Windows On Disk Management, right click on the extended partition area and select New Simple VolumeĪnd the rest of the steps are the same as creating a primary partition or volume. Creating logical drive inside an extended partition Right now this partition cannot be used to store data until a logical drive is created in it. In this example, the extended partition will be created in 1 GB size.Īfter running the command above, notice on the Disk Management that a new partition has been created with a dark green border line, indicating that it is an extended partition. The size parameter is optional, and if it is not used then the extended partition will takes up all the remaining unallocated space. The XXXX represents size specified in MB, where 1024 MB equals to 1 GB. The extended partition can be created with the command create partition extended size=XXXX. Notice that Windows will respond the command with a confirmation of the disk selection. As explained in the first step, in this example the extended partition will be created in Disk 1, and the command in this example will looks like as in below screenshot: Now run command select disk X, where X is the disk number where extended partition will be created. Notice that the prompt will be changed as shown in the screenshot below On the command prompt, type diskpart and press enter. Right click and choose Run as administrator. Open command prompt and run diskpart utilityĬommand prompt needs to be run with administrator privilege. Therefore, the further steps on the example are going to focus on Disk 1.Ģ. In this example below, both Disk 0 and Disk 1 has unallocated space.įrom the screenshot above, we can see that there is no need to manually create extended partition on Disk 0 because it already has three primary partitions in it and the fourth will be automatically created as extended partition. Open Disk Management console, see if there is unallocated space on the disk where the extended partition will be created. The step by step below will demonstrate how to create extended partition using command prompt and Windows Disk Management snap-in. Manually Creating Extended Partition in Windows Creating extended partition in Windows is done automatically when creating the fourth partition, but it can also be done manually on other partitions as well. Extended partition is needed to overcome the limit of MBR disk, which only allow 4 primary partitions created. An extended partition cannot store any data but it can contain multiple sub-partitions inside it, or in Windows it is referred as logical drive. Extended partition is different from primary partition.
