If you have used Windows Vista, you must be knowing about the in-built option to partition hard drives. Similar to that, Windows 7 too come with a built-in facility to create, resize and delete partitions from a HDD, which means you can shrink or extend the partitions.

The Disk Management utility is capable of shrinking and expanding partitions and it does not require any 3rd party utilities. This step-by-step tutorial helps you create, resize or delete a partition in Windows 7.

Step-by-Step Guide to Partition HDD in Windows 7

1. Go to Start -> Right Click on Computer -> Manage


2. Computer Management windows will open. Click on Storage -> Disk management


3. Select the Drive you want to partition. Right click on the drive and click on Shrink Partition.


4. It will query for the available disk space and then you will then be presented with a window showing you the Size of the Hard drive and the total amount available to Shrink. Enter in the amount you would like to shrink. This will be the size of the new partition. It can’t be more than the amount available to you and remember that Approx 1000 Mb = 1 GB


5. After entering the values, click on Shrink and wait for the operation to complete. Depending on the size of the drive and amount to shrink this could take a while. Once completed, you would see an unallocated space which is the size you just shrunk the volume by. Select it and right click and then select New Simple Volume


6. Follow the Wizard that appears and fill in the Size of the Partition. Normally the size to fill in is the size you just shrunk the drive by.

7. Assign a drive letter, pick one of your choice as it doesn’t make a difference.

8. Then on the Format page, Ensure NTFS is selected and then enter a name for your drive and click Next followed by Finish


9. That’s it! You have resized your hard disk and created a new partition without any third party software!

    Great tutorial….

    But, I guess the third party Partition Managers would be more better. Right?

    • http://techpp.com Raju

      in what way you think they are better? This one did the job for me without an issue!

    Do I have to back up my stuff, or will this procedure leave my stuff alone?

      backing up is always recommended

    Here’s how to format your newly created disk partition(s)-partition hard drive: 1. At the A> prompt, type format c: /s. The “/s” tells it to make the disk bootable by copying some elementary system files to the C drive. If you booted from a CD and intend to install the OS right away, you do not need to copy system files, in which case you can leave the “/s” off. 2. You will get a warning saying that this action will erase all data on the drive. This is normal, and since there is no data on the drive, just press “Y” and move on. 3. It will show the status as it happens. 4. If you created additional partitions on this drive, format those volumes now. Type “format d:” or “format e:”, where the letter corresponds to the volume you wish to format. Do not type the “/s” since you only want the C: drive bootable. Do this for all remaining partitions you created during the partitioning process. 5. When you are complete, you should be able to do a directory listing to be sure it is formatted by typing “DIR C:” at the command prompt. You’ll likely get a FILE NOT FOUND message, but that’s normal. At least the drive is set up.

    After creating a partition this way, would I then be able to install a different OS on the new partition? For instance, I have Windows 7 already installed, but the end result I am looking for is to be able to have Win XP installed as well, and be able to choose which OS to boot from when the pc starts up. Is this possible using the method described above? And once the partition is created how do I install Win XP on the new partition?

    I have a new vaio Z1 with 256 SSD but it is all in one drive. Can I use this method to partition my laptop drive. I want to keep 128 GB for OS and 128 for data but I am worried if partitioning the HDD and SSD are the same. I found a complicated way in another form but I am not expert, so i m afraid to do that


  • Luke

  • shirley

    How can you choose which disk the new partition allocated? I made 2, but it says can’t.

  • Michael

    Howerver, there are a lot of limitations on resizing partition in Windows 7 by useing the built-in disk management, such as you can not move partition, you can not change partition size as you want, …etc, to break these limitaions I think this article would give you a hand:

  • noufal

    it’s so helpful..thanks,thanks lot….

  • Mainong

  • Caesium

    Use paragon partition manager, the windows one is not much cop. The windows application cannot move files that are in use, whereas paragon reboots the machine and completes the operation in a linux shell, giving you more control.

    I tried it but unfortunately did not work! It came up with this message:

    Virtual Disk Manger
    The service can not be started, either because it is disable or because it has no enable device associated with it.

    The service is enable in system configuration, and, what enable device needs to be associated with it??

    Can any one help here please? I have Windows 7 64 bit Home premium.

    Does it affect anything on the current drive? Do we need to back up antthing?

  • Linda

    This was so easy to follow…. I just did mine! Thank you :)

  • Daniel Mirac

    I agree with Raju, any time we can do the job as effectively and easily as he describes here, why in the world would you want to buy new software?
