Part 1. Create a Partition for Windows 10 installation under Windows 8 or 7

As you can see in my disk management, I have a 160GB hard disk with a 30GB partition on which Windows 8/7 is installed and a 130GB empty partition. What I need to do now is to make a new partition for Windows 10 installation.

On EaseUS Partition Master, right-click on a partition, for example, Partition E and select Resize/Move. Drag the left border of Partition E, and shrink its size to 100GB to make 30GB free space to Windows 10 system partition (Windows 10 installation requires at least 16GB partition).
