2. Creating a Bootable USB Drive

To install Kali Linux, create a bootable USB drive using the ISO image.

Download Rufus from rufus.ie and open it.
Insert your USB drive and select it in Rufus.
Click Select and choose the downloaded Kali Linux ISO image.
Ensure the Partition scheme is set to MBR for legacy BIOS or GPT for UEFI systems.
Click Start to create the bootable USB drive. This process will erase all data on the USB drive, so back up important files first.

3. Boot from the USB Drive

Insert the bootable USB into the computer where you want to install Kali Linux.
Restart the computer and enter the BIOS/UEFI settings (usually by pressing F2, F10, F12, Del, or Esc during boot, depending on the manufacturer).
Set the boot priority to the USB drive and save the settings.
The computer will boot from the USB drive, and you will see the Kali Linux boot menu.

4. Start the Installation Process

From the boot menu, select Graphical Install for a user-friendly installation process.
Choose your preferred language, location, and keyboard layout.
The installer will detect and load components from the USB drive.

5. Configure the Network

Network Configuration: Enter your computer’s network details (usually DHCP will auto-configure this).
Hostname: Assign a unique name for your system (e.g., kali).
Domain Name: Leave it blank if you’re installing for personal use or add your network domain if required.

6. Set Up User Accounts and Passwords

Root User: Kali Linux no longer uses root as the default user. Create a new user and set a strong password.
Confirm User Details: Enter and confirm the password for added security.

7. Partition the Disks

Choose how you want to partition your disk. Beginners should select Guided – use entire disk:

Choose the disk for installation.
Select All files in one partition for simplicity.
Confirm the partition layout and select Finish partitioning and write changes to disk.
The installer will format the partitions and install the system files.

8. Install the System and GRUB Bootloader

The installer will copy files and install Kali Linux. This may take some time.
When prompted, install the GRUB bootloader to the master boot record. Select Yes and choose the appropriate disk.
Complete the installation by restarting the computer. Remove the USB drive when prompted.

9. First Boot and Post-Installation Setup

Boot your system, and Kali Linux will start. Log in using the user credentials you set during the installation.
Update Kali Linux: Ensure your system is up to date by running:

sudo apt update && sudo apt upgrade -y

Install Additional Tools: Use the Kali Linux metapackages to install tools as needed. For example:

sudo apt install kali-tools-top10
