Part 2: Preparing for Installation
To create a USB drive that can act as an installation disk for Kali Linux, you will need to create a bootable drive out of an ISO file.
An ISO file is a complete image of a disc, containing all the data needed to install an operating system. For Kali Linux, the ISO file acts as a digital version of an installation DVD, which you’ll use to create a bootable USB drive. This USB drive will enable you to install Kali Linux on your computer.
However, before downloading the ISO file, you must ensure it matches your computer’s architecture—64-bit or 32-bit. This choice is critical for compatibility and performance.
What Does 64-bit vs. 32-bit Mean, and Why Is It Important?
The terms 64-bit and 32-bit refer to how a computer’s processor (CPU) handles data. This matters because the operating system must match the architecture of the CPU.
64-bit:
Designed for modern systems.
Can handle large amounts of RAM (more than 4 GB), making it ideal for multitasking and running resource-heavy applications.
Offers better performance and efficiency.
32-bit:
Used in older systems.
Limited to 4 GB of RAM, which restricts performance.
Suitable only for basic tasks and lightweight applications.
If you install a 64-bit version of Kali Linux on a 32-bit machine, it won’t work. Conversely, installing a 32-bit version on a 64-bit machine will work but won’t utilize the system’s full potential. This is why identifying your system’s architecture is crucial before downloading the ISO.
How to Determine Your System’s Architecture
On Windows:
Press
Windows + Rto open the Run dialog.Type
msinfo32and press Enter.In the System Information window, look for System Type:
If it says
x64-based PC, your computer is 64-bit.If it says
x86-based PC, your computer is 32-bit.
On Mac:
Click the Apple menu in the top-left corner and select About This Mac.
Check the Processor or Chip:
If it says Intel Core 2 Duo, i3, i5, i7, or newer, your Mac is 64-bit.
If it says Intel Core Duo or Core Solo, your Mac is 32-bit.
Macs made after 2008 are almost always 64-bit.
Downloading the Correct Kali Linux ISO
Once you’ve identified your system’s architecture:
Visit the Kali Linux downloads page.
Choose the Installer ISO that matches your system:
Download the 64-bit ISO for 64-bit systems.
Download the 32-bit ISO for 32-bit systems.
(Optional) You can verify the ISO file’s integrity by checking its SHA256 checksum to ensure it hasn’t been tampered with.
Part 3: Create a Bootable USB Drive
To install Kali Linux, you’ll need a bootable USB drive. Make sure the USB drive is at least 8 GB in size to accommodate the Kali Linux ISO and its installation files. Here’s how to prepare it:
Before writing the ISO, you’ll need to format the USB drive to ensure it’s ready for use.
Format the USB Drive
Windows: Open File Explorer, right-click on the USB drive, and select "Format." Choose FAT32 as the file system and click "Start."
Linux/Mac: Use Disks (Linux) or Disk Utility (Mac) to format the drive to FAT32.
Write the ISO to the USB
Use a tool like Rufus or Etcher to create the bootable USB:
Rufus (Windows): Download and open Rufus. Select your USB drive, click "Select" to choose the Kali Linux ISO, and start the process.
Etcher (Windows/Mac/Linux): Open Etcher, select the Kali Linux ISO, choose the USB drive as the target, and click "Flash."
Once complete, your bootable USB drive will be ready for installing Kali Linux.
