You have to shrink the volume for the disk where Windows 10 is installed so that you can boot Kali Linux from that disk. To do that, first open Disk Management from the menu:

Then right-click on the Windows 10 installation drive, which is the C drive in my case, once done, select the Shrink Volume option:

Choose the amount of space to shrink. Once selected, choose the Shrink button to shrink the volume on Windows 10:

Step 3: Download Kali Linux Image

To boot Kali Linux on Windows 10, you will require an ISO image file of the Kali Linux operating system. It is up to you whether to download a simple Kali Linux ISO file or Kali Linux Live from here. Here, I am going with installing Kali Linux simple ISO file:

Step 4: Download and Install Rufus on Windows 10

You should also require downloading a Windows application called Rufus, which will be used in this process. Rufus is a desktop application designed for Windows systems that is used to creating a bootable USB. This tool will help you in making a Kali Linux bootable USB for running the operating system alongside Windows 10.

Most part of the installation is similar to the one we have performed, earlier, in our guide. There are some options that you have to choose carefully, such as selecting the default partitioning method as “Guided-use the largest continuous free space”. Then selecting your partition that you have created in Step 2, and ensure going with the option Automatically partition the free space. Further, you can pick the All files in one partition option from the menu, and then go with the finish partitioning and write changes to disk option for completing the disk partition:
