How to Make Drives When There Are 4 Primary Partitions Already

  • Contents:

    Many users know they are able to create new partitions even if Windows has been installed, and Windows built-in Disk Management is the tool that can help them do such an operation. Nevertheless, there is a big restriction when users create drives on a MBR disk: they can create 4 primary partitions at most. Therefore, the problem how to make drives when there are 4 primary partitions already is often asked. Next, we will introduce 2 solutions. One is provided by Windows built-in Disk Management utility, and the other is by MiniTool Partition Wizard.

    If users make drives in unallocated space by using Disk Management when there are 4 primary partitions already, Windows will prompt whether to convert basic disk to dynamic. At this time, they can do as told since lots of volumes can be created on a dynamic disk. Nevertheless, it is not easy to conduct such a kind of disk, and some Windows OS or programs do not support dynamic disk. For users who are unwilling to employ dynamic disk, please see the second solution.

    If users want to make drives when there are 4 primary partitions already, they can set one of the primary partitions except the boot and system one to logical, which can fix the issue easily. Once there is a logical drive, they can shrink it to release free space that can be used to create multiple new partitions. And MiniTool Partition Wizard can help make this setting without data loss. Detailed steps are as follows:

    1. Launch the recommended program to get its starting interface and then choose “Launch Application” to get the window below:

    2. Select one of large primary partitions which are not related to Windows (here we select partition H) and click “Set Partition as Logical”.

    3. Now we can see the selected partition has become logical, but it is only a preview effect MiniTool Partition Wizard provides. At this time, as long as users click “Apply” button on the top, the change will be applied. After that, they can shrink the logical partition via the function “Move/Resize Partition” to create space for creating new partitions.

    Now take one of the 2 ways to make drives when there are 4 primary partitions already.
