Creating a New Hard Drive Partition using Windows 7

Windows 7 has a built-in utility to create, resize, or delete hard drive partitions. No third party software utilities are required.

You are able to expand or condense partitions after creating them using the inherent function rather than blowing cash on a third party utility that is simply going to perform the actions in this step-by-step tutorial.

The process is fortunately simple and useful if you are ready to add a different operating system option with a hard drive partition. Whatever your purposes are, Windows7 actually makes is easy.

To begin, go to Start > Right-click Computer > Manage (or enter computer in the search and run box and select Computer Management from the results listing).

This is the computer management window which will open. Remember, this is a right-click to get the Manage option. Click on Storage > Disk Management. This is how you will be able to select the drive you want to partition. You should see a similar listing of all connected disks and drives after a scan of the system drives.

Choose which drive that you want to partition. There may be, of course, more hard drives on the system. External hard drives can be partitioned as well, but that is another matter. The focus will remain on partitioning an existing internal hard drive. Right-click on the drive that you want to partition and click Shrink Volume.

A query for available disk space will commence and next a window will be presented to demonstrate the size of the hard drive and what space is available for shrink. You will need to enter the amount that you want to shrink, or the size of the new partition. Obviously, it cannot be more than the amount of space available and the amount of space needed should have been carefully considered. There is no need to create an excessively large partition if it is not going to be used.

The "Enter the amount of space to shrink in MB value needs to be set. This basically cuts the selected amount of Megabytes from the current partition and makes it available for another one. Please note that you need to enter the amount in Megabytes in the menu. 1000 Megabytes are one Gigabyte, for 100 Gigabyte you would enter 100000 in the form.

Click Shrink after entering the values and the operation will take a period of time to complete, depending on the drive size and shrink amount selected. When it is complete, you will see an unallocated space representing this size selected.


Select this unallocated space and right-click and choose New Simple Volume. The setup Wizard will appear. Follow the steps and fill in the partition size. Typically, this is the same size as that selected for shrink, but may differ by a few megabytes.

Click Next and assign a drive letter of your choice. It is irrelevant which drive letter you choose as long as it is not already assigned. In this example, the drive letter M is chosen for this new partition, but you are free to select another free driver letter instead. Select NTFS and enter a name for the drive. Simply click finish and the partition has been created.


It is usually not necessary to use third party partitioning software under Windows 7 unless you run into error messages.

    What mental age of reader are you targeting with the first sentence? 10?

    Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.

    If your paymaster Microsoft permits it, of course.

    5. Rufus
    6. Ventoy

    PS. I hate reading these “SEO optimized” articles.

      I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.

    bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.

    ps…. time travelling?

    Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.

    I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:

    1) Too young to remember a time before W10 and W11 (doesn’t know better)

    2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)

    3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””

    4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows

    5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss

    Obviously that doesn’t cover everyone, there’s also the category that:

    6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now

    Have I missed any group off this list?

    1. Heinz Strunk said on September 19, 2023 at 3:57 pm

      You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.

      Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.

    Microsoft has removed KB5029351 update

    1. EP said on August 24, 2023 at 9:21 pm

      only from windows update though
      KB5029351 is still available from the ms update catalog site

  7. Anonymous said on August 24, 2023 at 11:05 pm

    1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.

    2. I have installed it in a 11 years old computer, and no problems at all.

    3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.

    This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
    Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.

    Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.

    Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.

    1. John G. said on August 25, 2023 at 12:08 pm

      Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.

    While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.

    My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
