Sooner or later, any user has a question about how to divide a hard disk, primarily due to the fact that the system may need to be reinstalled, and I would like the various files, including media files, to remain intact.

Addition to the above-mentioned file saving, when reinstalling the system, these actions are necessary for a faster complete scan of antivirus and antispyware programs, as well as for more rapid verification of the surface of partitions and their defragmentation. Also, according to some users, the creation of several virtual volumes contributes to the fact that the OS performance increases. Such a need may arise in the case of using multiple systems on a single disk.

Device partition

Each physical disk can be divided into several logical or virtual volumes. How to share a hard disk on Windows, will be discussed in this article.

On each created section you can make your own FS. Information about the new logical volume is placed in the partition table. In the first sector, owned by a physical hard drive, is the MBR - the master boot record. In it, 64 bytes are allocated for each virtual partition, 16 bytes fall on one record, that is, you can make 4 logical volumes on a single physical disk. This limit can be bypassed with the help of special programs.

Using Windows Embedded Software

Most recently, this OS did not provide the user with any tools to implement these actions. However, at the moment when asking the question of how to divide a hard disk on Windows 10, as well as on the 7-8th version, we can already say that it is possible not to use third-party programs. These versions already contain applications that allow the partitioning of the hard drive into various sections.

When dividing it is necessary to take into account that a part cannot exceed the whole. The application is launched from the command line or from the “Run” item (the “Super” (Win) + R key is the default hot combination). As a result, the “Disk Management” window will open, in which all physical volumes, as well as virtual partitions, will be shown if they have ever been created before and if they are supported by the OS in question.

It can also be accessed in another way: go to the “Administration” item located in the “System and Security” control panel and go there to the “Creating and Formatting Partitions”.

If you have a question about how to divide a hard disk, you must first decide on the volume that will be subjected to this procedure. In the context menu, select "Compress volume". The program will provide information about the total size of the disk, the available space for compression. Enter the size that we are going to compress, and click on the button of the same name.

There will be an “Unallocated” label. On it choose in the context menu "Create a simple volume." If you plan to create one additional partition, its size will be the same as it was previously released. If you plan several of them, then everyone needs to determine their volume.

In the next step, when answering the question of how to partition the hard disk on Windows, you need to select the appropriate letter designation of the partition and its file system. After all performed actions are confirmed, new partitions will be created and appear after the OS reboots.

However, it will no longer be possible to merge divided partitions into one using this program.

Disk partitioning during OS installation

If you bought a device without a pre-installed OS, then during the installation process, the user is prompted to select a disk to be installed. How to split a hard disk into parts in this case? You need to click on "Disk Setup", select the volume, click "Delete" />

Division of the hard disk with an application of third-party applications

Experienced users try to use not the tools provided by the OS itself, but third-party applications when they face the question of how to partition a hard disk. For the most part, these programs allow not only splitting a disk into separate sections but also then combining them into one volume. There are various modifications: both paid and free. Consider some of this list.

AOMEI Partition Assistant

 Using this program, it is easy enough to answer the question of how to divide a hard disk by 2. To do this, click on the physical volume, then select "Partition partition" />

It can be entered from the keyboard or by moving the slider to observe the dynamics of the size below. We confirm the changes made, after which the application splits the disk. Changes in the OS will appear after the reboot.

Acronis Disk Director

This application is proprietary, that is, commercial, closed source. Using this program allows you to answer the question of how to split a hard disk without loss. Actions to divide the hard drive can be carried out in two modes:

  • manual;
  • automatic.

Despite the apparent simplicity of automatism, it is easier to use the first mode.

Select the disk on which we are going to organize several virtual partitions. In the context menu, select "Split volume", specify its size and confirm the actions performed. Here, operations become pending. To apply them, click on the button “Apply pending operations” on the toolbar. The changes will take effect after the OS is rebooted.

Paragon Partition Manager

The functionality of this application is similar to the above. First, select Create partition, select the hard drive, determine the size and letter of the partition. FS should be NTFS. Confirm the pending changes and wait for the program to make the necessary changes, and then reboot the OS.

Finally

Within this article, different ways were considered, how to divide a hard disk. This can be done using the built-in software of Windows 10, as well as using the third-party software, both paid and free. Sometimes something in a given work program can go wrong, with the result that all the information may be destroyed, so always in the implementation of such actions need to make a backup of the most important files.
