gpg --verify SHA256SUMS.gpg SHA256SUMS

Step 2: Create Bootable USB Drive

You'll need a bootable USB installer to begin the installation process.

Creating Bootable USB on Different Operating Systems

On Windows (Using Rufus)

1. Download Rufus: rufus.ie
2. Insert your USB drive (8 GB minimum)
3. Launch Rufus (no installation required)
4. Configure Rufus:
   • Device: Select your USB drive
   • Boot selection: Click "SELECT" → Choose Kali ISO
   • Partition scheme:
     • GPT for UEFI (modern systems)
     • MBR for BIOS/Legacy (older systems)
   • File system: FAT32 (default)
   • Cluster size: Default
5. Click START
6. Choose write mode: ISO Image mode (recommended)
7. Confirm data erasure warning
8. Wait for completion (5-10 minutes)

On Linux (Using dd)

1. Insert USB drive
2. Identify the device:

lsblk

Look for your USB (e.g., /dev/sdb, /dev/sdc)

⚠️ CRITICAL: Ensure you have the correct device. Wrong device = data loss!

3. Unmount if mounted:

sudo umount /dev/sdX*

(Replace sdX with your actual device)

4. Write the ISO:

sudo dd if=kali-linux-2026.x-installer-amd64.iso of=/dev/sdX bs=4M status=progress oflag=sync

5. Wait for completion (10-15 minutes)

6. Safely eject:

sudo eject /dev/sdX

On macOS (Using dd)

1. Insert USB drive
2. Identify the device:

diskutil list

3. Unmount the disk:

diskutil unmountDisk /dev/diskX

Modern systems (2012+):

• Boot Mode: UEFI (recommended)
• Legacy/CSM Support: Disabled (unless needed)
• Secure Boot: DISABLED ⚠️ (Required for Kali)

Older systems:

• Boot Mode: Legacy BIOS
• Keep existing settings

Why disable Secure Boot? Secure Boot restricts loading of unsigned bootloaders. While Kali Linux can work with Secure Boot, disabling it prevents installation complications. You can re-enable it later if needed.

2. Boot Order

Set boot priority:

1. USB Drive (first priority)
2. Hard Drive/SSD (second priority)
3. Optical Drive (if present)
4. Network Boot (last)

Some systems have a one-time boot menu (F12, F8, or Esc) - use this instead of changing permanent boot order.

3. Advanced Settings (if available)

Enable:

• AHCI mode (for SATA drives - better performance than IDE)
• Intel VT-x / AMD-V (virtualization - useful for future nested VMs)
• Hardware virtualization extensions

Disable:

• Fast Boot (can interfere with USB booting)
• Secure Boot (as mentioned above)
• Intel Rapid Start (potential conflicts)

4. Save and Exit

• Save changes: F10 (usually) or "Save & Exit" option
• Confirm changes
• System will reboot

Troubleshooting Boot Issues

USB not detected:

• Try different USB ports (USB 2.0 often more reliable than 3.0)
• Recreate bootable USB with different tool
• Check BIOS USB support settings
• Ensure USB Legacy Support is enabled (older systems)

Secure Boot error:

• Confirm Secure Boot is fully disabled
• Some systems have "Other OS" vs "Windows UEFI mode" - choose "Other OS"
• Check for "Secure Boot Keys" option - clear/delete keys

Boot loop:

• Reset BIOS to defaults
• Try Legacy BIOS mode instead of UEFI
• Check USB drive integrity

Step 4: Boot from USB Installer

Now you'll boot into the Kali Linux installation environment.
