How to create a new partition in Windows 10/8.1/8/7/XP? AOMEI Partition Assistant can help you create partitions on your disk without any limitation.

About Creating Partition

To create partition is actually to partition the hard drive. Only after you create the partition(s) on a disk can you make use of the disk to save all kinds of data. All physical parameter of a disk are set when you create partition(s) on it, including MBR (Main Boot Record) and the destination for storing boot record backup. For other information later needed for the management of file system and other operating systems, it will be achieved by later advanced format.
What are the advantages of creating partitions? Generally speaking, creating more than one partition enables you to have an operating system separate from data, deploy multi-boot setups, and keep frequently used programs and data near each other. Therefore, you can manage your computer with ease. If there is only one partition (namely C drive) on disk:
  • When recovering the system, the whole c disk (the system disk) will be formatted. If all data are saved in c disk, they will all be wiped and cannot be restored.
  • Too many other things in system disk will slow down the system running.
  • If there are several partitions on the disk and each partition stores different kinds of data, then it is convenient for the users to manage them.
  • After partition creation, the size of the cluster will decrease, which improve the efficiency of data storage. (Cluster is the distributive minimum disk space to save files. According to the stipulation of the operating system, a cluster can only be used to store one file. Therefore, the space occupied by files can only be integer times of the size of a cluster. However, if the size of a file is smaller than that of a cluster, the extra space in the cluster will be wasted. Thus, generally speaking, a small cluster is better)
    Consider all the reasons above, it is necessary to create more than one partition on a hard disk.

Before You Do

For MBR disk, please check how many partitions are already on the hard drive. Because MBR disk supports creating up to 4 primary partitions. If the number of partitions reaches the upper limit, please visit how to convert to logical partition to change one primary partition to logical one and then you can create partition(s) on it. For GPT disk, you can create partitions without limitation and you can have more primary partitions. However, the Windows implementation restricts this to 128 partitions.

How To Create Partition?

AOMEI Partition Assistant provides two ways to create the partition, please choose the one which is more convenient for you.
Tips: No matter which way you choose, please download AOMEI Partition Assistant in order to follow the below steps.
Solution  1: Create partition with unallocated space
Step1:  Install and run AOMEI Partition Assistant on your computer. Right-click the unallocated space and select "Create Partition" in the left panel (if there is no unallocated space, please go to Solution 2).
Create Partition Unallocated Space
Step2: In the pop-up window, click "Advanced<<" to specify the information for the new partition, including partition size, partition label, drive letter, files system (NTFS or FAT), and the partition type (logical or primary). You can also specify the size of the new partition by dragging the both edges. When all settings are completed, click "OK" to continue.
Edit New Partition
Step3: Now you can preview the new created partition. Click "Apply" on the toolbar to commit the "Pending Operations".
Tips:
  • We suggest you set the file system as NTFS.
  • If you set the drive letter as "None", the partition will be hidden, in other words, you cannot view it in "My Computer".
Solution 2: Create partition without unallocated space (within existing partition)
If there's no unallocated space, AOMEI Partition Assistant also supports creating the partition from an existing partition (this way will reduce the size of the existing partition).
Step1: Install and run AOMEI Partition Assistant. Right click the partition on which you are going to create new partition and select “Create Partition” in the drop-down menu.
Create Partition
Step2: In the pop-up window, click "Advanced<<" to specify the information for the new partition, including partition size, partition label, drive letter, files system (NTFS or FAT), and the partition type (logical or primary). You can also specify the size of the new partition by dragging the edge circle rightwards or leftwards. When all settings are completed, click "OK" to continue.
Resize Partition
Step3: You can preview the new created partition. To save the changes, please click "Apply" on the toolbar.
Apply
Notes:
  • If you create partitions on SSD (Solid State Drive), it's recommended to tick the check box “Partition alignment for SSD” to align the partition(s) on SSD option.
  • If the disk where you want to create a partition is in MBR style and there are already 4 primary partitions on it, you cannot create a primary partition on this disk anymore but if you do really want to create a primary partition on it, then you need to convert one of the primary partitions on the disk to a logical partition first.
