Dual Boot Windows 11 with Windows 10

If you are interested in going through the Insiders Preview of Windows 11 and having some choices regarding the place of installation of the new OS, it’s a good idea to set up the OS on a dedicated computer. This implies that you have to own an extra PC. The OS can also be installed as a virtual machine through a free VM, but that could make your system lag if there is insufficient memory. In this case, a dual-boot setup is a much better option. Use a system that has an old version already installed (such as Windows 10). Then you can install Windows 11 as well. Every time your computer will boot up, you must choose between using Windows 10 or Windows 11. But, if you are wondering that how to dual boot Windows 11 with Windows 10, we have got you covered.

It is possible to install Windows 11 by simply running your setup.exe file from your Windows Source folder. This becomes more useful if there is no bootable flash drive available. This method includes several different steps, so you should follow whatever is applicable in your system.

Steps To Dual Boot Windows 11 With Windows 10?

Step 1: Shrink a Volume

First, you have to shrink the existing partition to make room for installing Windows 11. Press the keyboard shortcut Win + R to start Run. Type in “diskmgmt.msc” then click OK so that the Disk Management tool opens.

In the title “Disk”, right-click on the volume with adequate free space and then click Shrink Volume.

A dialog box should appear, where you have to enter the total space that you want to shrink in MBs, then click on Shrink. For instance, if the current volume shows available space as 153122 MB (150 GB), you might enter 70000 on the Shrink dialog box. This will ensure that your current volume shrinks to 80 GB, while the remainder 70 GB will exist as unallocated space.

Step 2: Create New Volume

For creating new volume, you have to right-click where it shows Unallocated space then choose New Simple Volume.

Here, the New Simple Volume Wizard will pop up, and you click Next. Now, you can enter the required size for your new volume, then click Next. Note that you have to ensure that enough space has been allocated for the installation of Windows 11.

Next, choose “Assign the Following Drive Letter” option and click Next.

Choose Format This Volume using the settings as follows and choose: Allocation unit size – Default, File System – NTFS, Volume Label – Windows 11.

By labeling your volume, you are actually making it easier for you to recognize this drive as you install it. Moreover, you can go through the “Perform a Quick Format” option. Lastly, select Finish, and you have created a new volume.

Step 3: Installing Windows 11

Connect the bootable Window 11 drive to the computer. In case you cannot get your hands on a bootable flash drive, you will have to mount the ISO image of Windows 11.

For doing this, right-click on your ISO image and select Mount. After the image has been mounted, it can appear as one new drive under the This PC section.

Then, open your bootable flash drive and mounted ISO in the File Explorer. Now, open this Sources folder, then run your setup.exe file. Select Yes once you are prompted by the User Account Control (UAC).

Then, on your screen for Windows Setup, click on the No thanks button to continue. Accept all required notices as well as license terms and click on Next.

Choose the “Custom: Install Windows only (advanced)” option. Once you reach the ‘Where do you want to install Windows option’, select the Windows 11 volume, then click Next.

Once all of this is done, Windows 11 will begin to install. This may take a bit longer.

While installation is in progress, the computer will restart with Windows Boot Manager showing up. You have to click on the first Windows Setup option for carrying on with your setup. If you use a leaked Windows 11 version, you might see Windows 10 and not Windows 11.

After the setup is completely done, you can restart the computer, and the dual-boot option will be shown upon the Boot Manager screen.
