Two ways to create partition in Windows 8 or 8.1 without formatting

• 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?"
