Computers are devices that are capable of helping people out in almost every part of life. In fact, there has been no other man made thing or device that has influenced the lives of people to such an extend as computers have. Hence it is safe to say that almost every single person would be dependent on a computer to carry out some kinds of works. So you would need to make sure that you are aware about rectifying some of the most common troubles that arise as far as a computer is concerned.

And when it comes to such issues, repartitioning the disk drive on a computer is one of the most commonly occurring problems. There are numerous different situations that would need you to do the repartition. Resizing the drive volumes, needing to install multiple operating systems, reinstalling OS etc. are some of the many situations that cause the need for repartitioning. This article deals with some of the most effective methods to carry out the repartition.

What is an extended partition on a hard drive?

The extended partition is that which refers to the Master Boot Record (MBR) disks. The maximum primary partitions are 4. Other combinations are less than 4 primary partitions and 1 extended partition. And in the extended partition there can be any number of logical partitions. The only limit is that you would be able to use only the available drive letters for the partitions. If a partition has unallocated space inside it, then it can be allocated to create a new drive.

If you are using disk management tool, then you wouldn’t be able to extend a primary partition. You would have to delete all the extended partition and then create a new one. if you are a software like partition assistant, then you would be able to do extension without deleting the existing partitions.

How to Create an extended partition:

1. Check unallocated space:

The simplest method is to use the disk management console in order to make sure that there is unallocated space on the drive in order to create the extended partition that you need.

2. Run diskpart through command prompt:

The next step would be to open the command prompt dialog box and then to run the disk part utility software in order to make the partition. Make sure that the command prompt is run as an administrator.

Type in diskpart and then press enter. The next step would be to select the drive that you need to extend.

3. Select disk:

Use the command ‘select disk x’ . this would select the disk and the x is replaced with the number of the disk.

4. Create extended partition:

The next thing to do is to create the extended partition with the command ‘create partition extended size= xxxx. The xxxx should be replaced by the size of the extension that you need.

After this is done, if you check the disk management would show the extension for the disk drive that you have just extended. This is way to check whether the repartition has been successful.

Now you have to create a logical drive to use the new partition to store data. 

5. Logical drive inside extended partition:

Right click on new extended partition area on Disk Management and click on “New Simple Volume”. After that just follow the step of creating primary partition.
