Windows8.1 extended partition method

Click the “Start” menu to find the “Command Prompt” from the attachment, right click and select “Run as administrator” to open the Command Prompt window, enter the “diskpart” command to enter the DISKPART state. Then follow the steps below:
1. Select the physical disk
Input“select disk N”Select the physical disk, where “N” represents the first physical hard disk. If you want to operate on the first physical hard disk, you should enter “select disk 0”, and so on.
2. Create extended partition
input “create partition extended” command, the system will automatically create an extended partition after execution, all the free space behind the primary partition will be occupied. When you are done, you can exit the command prompt and no longer have to enter the commands to create a logical partition, because the system uses all of the extended partitions to create a logical partition. Ok, now go to the "Computer Management & Rarr; Disk Management" window and you will find the extended partition that has been created. Right-click and select “New Simple Volume”, and the “New Simple Volume Wizard” will pop up (ie create a logical partition). Follow the wizard prompts to specify the size of the simple volume. The next operation is very good. Easy
