The Technical Preview Edition of the next Windows operating system - Windows 10 has been released. It adds many new features, such as "Multiple Desktops" which enables users to use multiple desktop environments; the users can switch between different environments depending on their requirements; as for advanced users, Command Prompt supports paste button which allows the users to paste files into Command Prompt directly and quickly. With these new functions, more and more users want to install this new system. But on the other hand, they don’t want to give up Windows 7 or Windows 8/8.1. What should they do? In this article, we help you make a dual boot Windows 10 and Windows 7 or 8 environment on the same computer. The things you need to do are as followings.

1. Create a new partition for Windows 10.
2. Install Windows 10 on the new partition.

Usually, the common way for the users of Windows 7 or 8 to create a new partition is using built-in Disk Management. However, in order to help you finish the task more easily, you can choose a free third-party partition software - AOMEI Partition Assistant Standard.

Disk Management

Disk Management is a built-in tool in Windows operating system. It can help you create/shrink/extend/delete partition. You can enter this tool by right clicking "My Computer" -> "Manage" -> "Disk Management". To create a new partition, if there is no unallocated space on hard drive, you should shrink partition to get it at first. And then right click on the unallocated space and choose New Simple Volume.

AOMEI Partition Assistant Standard

AOMEI Partition Assistant Standard is free partition management software, apart from creating partition, it supports moving partition, merging partition, making bootable CD, converting disk style between MBR and GPT, copying disk, migrating OS to SSD/HDD and so on.

This software offers two ways for you to create partition. One is creating partition within unallocated volume; another one is creating partition when there is no unallocated space. You can choose one depending on yourself.

The following steps are creating a partition when there is no unallocated space on hard drive.

Step1: Download AOMEI Partition Assistant Standard, install and open it. Right click any partition which has enough unused space (here take E for example) and choose "Create Partition".

Step2: Move the slider bar in the middle to decide the size of new partition you want to create. And then click "OK".

Step3: Click Apply to commit the changes.

1. Insert an installation of Windows 10 DVD or USB flash drive into your PC and choose language and keyboard layout. Then click Install now.

2. After allowed by license agreement, click "Custom: Install Windows only (advanced)".

3. You will be asked to choose where you want to install Windows 10. Remember to choose the new partition you have created as destination. Then click Next.

4. Then Windows will start to install without asking anything. You just need to wait patiently.

Here take Windows 7 for example, it is same with Windows 8/8.1. After you finish installing and boot your computer at first time, there will be a boot menu which makes you choose boot Windows 10 or Windows 7. Windows 7 is default, which means if you don’t choose boot Windows 10, your computer will boot Windows 7 automatically.
