2. **Create Bootable Installation Media**:
**Use a USB Drive or DVD**:
For USB: Use tools like Rufus (Windows), Etcher (Mac), or the `dd` command (Linux) to create a bootable USB drive from the downloaded ISO.
For DVD: Use disc burning software to write the ISO to a DVD.
3. **Prepare the System for Installation**:
**Backup Data**: If you are installing Kali alongside another operating system, back up any important data.

Disk Space: 20 GB or more
Graphics: VGA compatible
4. **Boot from Installation Media**:
**Change Boot Order**: Restart your computer and enter the BIOS/UEFI settings (usually by pressing F2, F10, or DEL). Set the boot order to prioritize the USB drive or DVD.
**Start Installation**: Insert the bootable media and restart the computer. Select the appropriate option to boot from it.
5. **Begin the Installation Process**:
**Select Install Option**: When prompted, choose either the graphical or text-based installation option.
