Why we need to partition a Windows 8 or 8.1 hard drive? On the one hand, it is for data safety - if your Windows 8/8.1 hard drive only has one partition including Windows, boot files, programs, documents, photos and so on, when there is something wrong with your system, all data on the partition may be lost.
