🖥️ Method 3: Dual Boot Kali with Windows

This is best if you want full performance with no virtualization overhead. But ⚠️ CAUTION: dual boot can break your system if done wrong.

1. ⛑️ Backup your data from Windows.
2. Download Rufus and make a bootable Kali USB:

8. Install GRUB on your main disk (usually /dev/sda).
9. Reboot → you’ll see Kali and Windows options.

✔️ Done! You now have a dual boot Kali + Windows setup.
