Step 1: Backup Important Data
Before making any significant changes to your system, it’s crucial to back up all important data. This ensures that if anything goes wrong during the installation of Kali Linux, your data will remain safe. Use cloud storage services or external hard drives to create backups of your vital files.
Step 2: Download Kali Linux
Visit the official Kali Linux website to download the latest ISO file. Ensure you are downloading the version compatible with your hardware (32-bit or 64-bit). Store this ISO file in a known location on your Windows system, as it will be needed for creating a bootable USB drive.
Step 3: Create a Bootable USB Drive
You will need a USB drive (at least 8 GB) to create a bootable installer for Kali Linux. Use tools like Rufus or balenaEtcher to create this bootable USB drive. Open the tool, select the downloaded Kali Linux ISO file, and choose your USB drive. Follow the prompts to complete the process.
Step 4: Partition Your Hard Drive
To install Kali Linux alongside Windows, you need to create a separate partition on your hard drive. Here’s how:
- Open Disk Management by right-clicking the Start button and selecting it from the menu.
- Locate your main disk, right-click on it, and select Shrink Volume.
- Enter the amount of space to shrink (this will be the space allocated for Kali Linux) and click Shrink.
- Your unallocated space will now appear. Right-click on it and select New Simple Volume if you want to format it later in Linux.
This partitioning step is essential in creating room for your new operating system without affecting your Windows installation.
Step 5: Install Kali Linux
Insert the bootable USB drive into your computer and restart it. You may need to access the boot menu (usually by pressing F12 or Esc during startup) to select the USB drive as the boot device. Once the Kali Linux installer loads, choose Graphical Install and follow these steps:
- Select your language, location, and keyboard layout.
- When prompted, choose Manual Partitioning and select the partition you created earlier.
- Format the partition to ext4 and set the mount point as
/. - Proceed with the installation following the on-screen instructions. Be sure to install the GRUB bootloader when prompted, as this will allow you to choose between Kali and Windows at startup.
Step 6: Reboot Your System
Once the installation is complete, remove the USB drive and restart your computer. You should see a boot menu allowing you to choose between Windows 10/11 and Kali Linux. Select the OS you wish to use and enjoy your dual boot setup!
Extra Tips & Common Issues
Be aware that issues such as incorrect boot order settings or GRUB not appearing can occur. To fix boot-related issues, you may need to adjust settings in BIOS/UEFI. Additionally, always ensure that your system’s secure boot feature is disabled for Linux installations to prevent conflicts.
