How to create a dual-boot setup on Windows 11

Dual Boot Setup on Windows 11

To run two or more operating systems separately, you can set up a dual-boot configuration on Windows 11. You can use apps that are incompatible with the most recent release by using this approach to run previous editions (such as Windows 10, 8.1, or 7). You can install previews of later versions of Windows 11 to try out new features without having to change your system. Alternatively, you can install an operating system from a different platform, like Linux. Even if virtualization is an option, a dual-boot system will have full access to the hardware for improved performance and usability. In this guide, you will learn how to create a dual-boot setup on Windows 11.

In an ideal world, you could use a different computer with a different operating system. But a dual-boot system makes it possible to run Windows 11 along with Insider preview versions for the Dev, Beta, Release Preview Channels, or another version.

Right-click the partition and select the Shrink Volume option.

Disk Management
