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 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 the other is
Windows 8 built-in Disk Management. Some 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, such as "You cannot create a new volume in this
unallocated space because the disk already contains maximum number of
partitions." and "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?" These
two errors are due to there are already 4 primary partitions on the MBR disk. To
solve these problems, you can first convert one data partition
to logical and then continue to create new partition on the logical
partition.
