How to Create partition on Windows – The Quickest way

When you have to deal with lots of files and folders, a separate hard disk partition seems a good option. Creating partition during boot while installing a new Windows Copy is the not a difficult thing, but did you know that you can create partition on Windows operating system as well. This method saves your time in creating, shrinking, extending partitions. It can be done easily with disk partition manager that comes in the bundle of utility software that Microsoft ship Windows operating systems with.

You need to open Disk partition manager to create partition on Windows and much more that you are going to do. Lets start it by locating from Start Menu Search bar. Just search “hard disk” or “create hard disk”. Manager will pop up in the results. Open it.

Opening Disk Partition Manager in Windows



First start with an easy one. Creating partition on hard disk from Unallocated space. If you want to create a new partition on Windows then this is the easiest process to begin with,

A. Creating Partition on Hard disk from Unallocated space

  1. Right click on the block that says ” Unallocated space ” and click on the “ New Simple Volume” from the menu. Partition wizard will open.

  2. Enter the amount(in MBs) you want in your new partition drive. You can calculate how many GBs you want. Make sure the size you enter is is equal to or under what is given in Maximum Disk Space in MB. Click on next. Note – 1 GB = 1024 MB

  4. In the Volume Label  box, type the name that you want it to be. Naming a drive helps in avoiding confusion. You can change it later as well. Here in the screenshot, we changed it to “My Drive” for showing you as an example. Click on Next and then Finish.

You have successfully created a partition out of unallocated space. Whenever you try to create partition on Windows, keep in mind to leave appropriate unallocated space for future requirements else you might need to shrink space from other partitions.


B. Shrink partition to create space for other drive or other purposes

When you run out of space in a partition or simply looking to scrape some space for the Linux distro which are you planning to install, shrinking a partition with enormous amount of untapped space helps you in doing so. It also comes handy when you want to create partition on Windows.

I would recommend not to shrink space from the drive in which your Windows is installed or it might cause problems later on. The thumb rule is to keep the size of Windows installed partition with the size of at least 30 GB.

  1. Right click on the partition you want the space to shrink from. A menu will appear. Select “Shrink Volume”.

  2. Second line will tell of how much space is available you can actually shrink.

  3. In Enter the amount to shrink in MB, put the amount of space you want, keeping in the mind the amount available to shrink. Click on the Shrink  button and you are done.

The reduce space will be available in the form of unallocated space. You can either use this space to create a new partition from the method A given above or add space to an existing drive by extending partition option which we will be learning in the method C  given below.


C. Extend partition free space by using allocated space

If your partition is almost on the verge of becoming full with no space left, and you don’t want to create new partition or store files in another partition then extending partition space comes handy.

Remember that you need unallocated space for extending space in a partition. You can do it by following Process B, given above.

  1. Right click on the partition which you want to extend space of.

  2. Click on next, and the below menu will appear.
  3. Select the amount you want to extend, keeping in mind the Maximum available space in MB  given there.

  4. Click on next and you are done.


These were the easiest methods to manage, create partitions on Windows 7, 8 and more. Creating and managing partitions is easy. Make sure you don’t end up deleting partitions with important data. We suggest you to name them accordingly for easier differentiation. You can any partition them by a single click on partition drive and pressing F2 button the on keyboard.

    I am not able to extend C, even though I tried your method?

      I suppose your C drive has the Windows installation? Then sorry to tell you but you cannot extend/shrink System partition as it contains System files.
