For this guide, we’ll use Parrot Security Edition.
Step 2: Verify ISO Integrity
# Download the SHA256 checksum file
wget https://download.parrot.sh/parrot/iso/5.3/Parrot-security-5.3_amd64.iso.sha256
# Verify the downloaded ISO
sha256sum -c Parrot-security-5.3_amd64.iso.sha256
Step 3: Create Bootable USB
Using dd command (Linux/macOS):
# Identify your USB device
lsblk
# Create bootable USB (replace /dev/sdX with your USB device)
sudo dd if=Parrot-security-5.3_amd64.iso of=/dev/sdX bs=4M status=progress
Using Rufus (Windows):
- Download and run Rufus
- Select your USB device
- Choose the Parrot Linux ISO
- Click “Start” to create bootable media
Lab 2: Installing Parrot Linux
Step 1: Boot from USB
- Insert the USB drive into your target machine
- Boot from USB (usually F12, F2, or Del during startup)
- Select “Boot from USB” in BIOS/UEFI settings
Step 2: Live Environment Testing
When Parrot Linux boots, you’ll see the MATE desktop environment. This is a live session where you can:
- Test hardware compatibility
- Explore the interface
- Run preliminary security tools
- Check network connectivity
Step 3: Installation Process
- Launch Installer: Click the “Install Parrot” icon on the desktop
- Language Selection: Choose your preferred language

- Partitioning: Choose partitioning scheme:
- Guided – use entire disk: Simplest option
- Manual: Advanced users can create custom partitions
Recommended Partition Scheme:
/boot - 512MB (ext4)
swap - 2GB (equal to RAM)
/ - 20GB (ext4, root partition)
/home - Rest (ext4, user data)
- Installation: The installer will copy files and configure the system
- Bootloader: Install GRUB to the master boot record
