Stepwise guide: How to dual boot Windows 11 and Windows 10

Whenever you need to make significant modifications to your computer, it is important to be adequately prepared beforehand. In order to successfully set up a dual boot between Windows 10 and 11, please ensure that the following tasks have been completed:

Before you do:
Verify that your computer meets the system requirements for Windows 11 to ensure it runs normally.
Take the precautionary measure of creating a full system backup. This step is essential to safeguard against unforeseen system issues that may arise due to inadvertent errors during the process.
Obtain an external USB flash drive with a capacity of at least 16GB. This flash drive will serve as the installation media to download and install Windows 11.

Stage 1: Creating Windows 11 Installation Media

To begin the process of dual boot Windows 10 and 11, you first need to download Installation Creation Tool.

Step 1: Connect the prepared USB to your PC. Visit the official Microsoft website and download the Windows 11 media creation tool, which will help you create a bootable USB.


Step 2: Run the tool and select your preferred language and Windows 11 edition. Click "Next" to proceed.


Step 3: Choose the option for a USB flash drive and select "Next".


Step 4: Install Windows 11 onto the USB and safely remove the USB. Congratulations, you now have the Windows 11 operating system on your USB.

Stage 2: Creating a new partition for dual boot Win 10 and Win 11

Once you have downloaded the Windows 11 files, it's essential to decide where to install it. Since two different systems cannot be installed on the same partition, creating a new partition for Windows 11 installation on your current Windows 10 computer is necessary.


• A smooth installation process requires at least 20 GB of free hard disk space; otherwise, you may encounter the error code 0x80070070.

• If you have two separate hard drives on your computer and intend to dual boot Windows 10 and 11 on them individually, you can skip this part.

To create a partition using Disk Management, you need unallocated space on your disk. If it is not available, you should shrink existing partitions first to obtain unallocated space. Follow these specific steps:

Step 1: Right-click on the partition you wish to shrink and select "Shrink Volume".


Step 2: In the pop-up window, enter the desired amount of space to shrink and click "Shrink". This action will create unallocated space.


Step 3: Right-click on the unallocated space, select "New Simple Volume," and click "Next" to continue.


Step 4: Follow the wizard's instructions to set the volume size, drive letter, and file system according to your preferences. After completion, you will have a new partition on your disk.

Stage 3: Installing Windows 11 on the New Partition

Once you have Windows 11 and the new partition ready, it's time to proceed with the installation.

Step 1: Insert the USB with the Windows 11 OS into your current Windows 10 computer and restart it. Access the BIOS/UEFI interface and set the USB as the primary boot device.

Step 2: Restart the computer and boot from the USB.

Step 3: The Windows Setup interface will appear. Select the appropriate parameters and click "Next".


Step 4: Click the "Install now" button.


Step 5: Enter your product key if you have one. Otherwise, click "I don't have a product key" to skip this step.


Step 6: In the new window, select "Custom: Install Windows only (advanced)".


Step 7: Choose the new partition where you want to install Windows 11. Click "New" and then "Next".


Step 8: Configure any necessary settings and patiently wait for the installation process to complete.


Eventually, your Windows 10 computer will have Windows 11 installed, enabling you to seamlessly switch between the two operating systems whenever you wish.

Stage 4: Setting the Default Operating System

Once you have completed the dual boot setup of Windows 10 and 11, each time you boot your PC, a boot menu will appear, giving you the choice between the two systems. You can select and load into either Windows 10 or Windows 11 based on your current requirements.

If you don't make a choice immediately, your previous Windows 10 will load automatically. However, if you plan to use Windows 11 frequently, you can click "Change Defaults or Choose Other Options" at the bottom of the boot menu and follow the prompts to set it as the default system.
