Create a 4th primary partition under Windows Server 2008

Windows Server 2008 disks are divided into MBR and GPT partitions. This article only discusses MBR (the number of primary partitions for GPT, which is not a problem at all...). In theory, an MBR disk can be divided into up to four primary partitions, or three primary partitions and one extended partition. However, in practice, it is found that when the fourth primary partition is created through disk management, the system automatically converts it into an extended partition: What is going on? Is it true that the theory of supporting up to four primary partitions is wrong? In fact, the fourth primary partition can be created by the diskpart command. The steps are as follows: 1. Enter the diskpart interface and select the disk to be operated. 2. Create a primary partition on the disk: create partition primary. At this time, you can see the newly created primary partition in disk management: then give it After assigning the drive letter and formatting, it can be used normally: PS: When creating the primary partition, you can also specify the size of the partition. Specifically, in the diskpart interface, use the help create partition command to view the help documentation.
