How to install kali kinux on usb drive or pen drive?

To install Kali Linux on a live USB drive, you can follow these steps:

1. Download the Kali Linux ISO image from the official Kali Linux website 

2. Download and install a tool such as Rufus   to create a bootable USB drive.

3. Connect the USB drive to your computer and launch Rufus or Etcher.

4. Select the Kali Linux ISO image and the USB drive as the destination.

5. Choose the "Create a bootable disk using" option and select "ISO Image" in the dropdown menu.

6. Click on "Start" and wait for the process to complete. This will take a few minutes depending on the speed of your computer and USB drive.

7. Once the process is complete, eject the USB drive and insert it into the computer you want to use Kali Linux on.

8. Boot the computer from the USB drive. You may need to change the boot order in the BIOS to ensure the USB drive is prioritized.

Once the Kali Linux live environment loads, you can either use it directly from the USB drive or install it on your computer's hard drive using the installer icon on the desktop.
