Dual Boot: Windows 11 and Kali Linux

After running Kali Linux as a live OS, from a USB-drive I thought it would be smoother to just have access to a linux distro directly installed on the PC instead of carrying around the USB-drive all the time.

When you want to run two operative systems on your computer it is often referred to as dual booting and using it can be pretty easy after you have prepared the necessary steps.

You will need a USB-drive for putting the Kali Linux ISO file on (I used a 16 gb one) and some 40 gb of space to spare on the computer that you want to dual boot. 

The following are the steps I took:

1. First you want to create a partition with descent amount of available disk.
   Start computer management on the computer that you are going to dual boot. Find your primary partition, right click it and shrink it by roughly 40000 mb. This will create around 40 gb of free unallocated space to use.
   
   
2. Download Rufus and download the latest Kali Linux ISO for bare metal installations. Bare metal simply means that it gets installed directly on the computer, not a virtual machine or a USB.
   
   
3. Now run Rufus and flash the Kali Linux ISO to the USB-drive. I used the option "DD image" that pops up. Leave the USB-drive plugged in.
   
   
4. Boot into UEFI of your computer and turn fast boot and secure boot off, then boot from the USB. Run the graphical installer and when it comes to partition, make a main partition with about 35 gb and then a swap partition with the rest (about 5 gb). Once you're near the end of the installation, it will ask you to unplug. Do so and continue to boot.
   
   
5. You will notice that you now get the option of choosing what to boot into when starting or restarting the computer. In my case it auto boots to Kali if I just leave it for a few seconds, but using the arrow keys and enter key I can choose between my Windows 11 and Kali Linux.
   
   
6. On your Kali installation you might want to open the terminal (ctrl + alt + T) and enter the following command in order to update and upgrade the OS/programs.
   
   sudo apt-get update && apt-get upgrade
   
   
7. Don't forget to customize your installation further, such as rearranging the task bar, installing keyboard layouts and choosing a nice background.

Best of luck with your dual booting!
