Win7 disk management extended partition creation method

In win7, there is no option to create extended partitions in the default disk management. You can only create 3 primary partitions first, and then create extended partitions by default. To create extended partitions directly, you must use cmd to operate. Specific creation method steps: 1. Run CMD to enter command line 2. Then run DISKPART, enter DISKPART3. Run LIST DISK to display the disk list. If there are two disks connected, 0 and 1 will be displayed, where the master is 0 and the slave is 14. Run SELECT DISK 0, select the first hard disk 5. Then enter CREATE PARTITION EXTENDED to create an extended partition.

Note: This extended partition will include all free disk space. To limit the size of the win7 extended partition, you need to use the parameter size to limit it later, such as size=1000 (the default unit is MB).
