How to Create New Partition in Windows 8 or 8.1 without Formatting and Reinstalling System?

When you have a new disk, you can create new partitions to help you manage files and documents better. Usually, we suggest at least two partitions, one system partition and one data partition. Of course, three or four partitions will be better; because it will help you classify the files and documents more distinctly. How to create partition in Windows 8 or 8.1 without formatting and reinstalling system?

Here, I will introduce you two ways to create partition in Windows 8, one is AOMEI Partition Assistant [ Download ], and another is Windows 8 built-in Disk Management. Two points are worth mention here:

  • On MBR Disk, it can include at most four primary partitions, or three primary partitions plus one extended partition, which can include several logical partitions.
  • On GPT Disk, it can include at most 128 primary partitions with no extended partition or logical partition.

Compared to AOMEI Partition Assistant, Windows 8/8.1 built-in Disk Management has some disadvantages. For example, you may get some error messages when creating a new partition.

  • "You cannot create a new volume in this unallocated space because the disk already contains maximum number of partitions."
  • "The operation you selected will convert the selected basic disk(s) to dynamic disk(s). If you convert the disk(s) to dynamic, you will not be able to start installed operating systems from any volume on the disk(s) (except the current boot volume). Are you sure you want to continue?"
