• KDE
• i3

Install example:

sudo apt install kali-desktop-gnome

Common Installation Issues and Fixes

• GRUB not installing: Try manual partitioning or “Force GRUB installation” in advanced options during setup.
• Black screen on boot: Use the “nomodeset” boot option or disable 3D acceleration in VirtualBox.
• Network issues: Install missing firmware via USB or verify network adapter settings.
• Installation freeze at base system: Ensure sufficient RAM (2GB+), verify ISO integrity, and enable network connectivity.
• “No root file system defined” error: Assign proper root partition with ext4 filesystem.
• Failed to install Linux kernel: Use 64-bit ISO if hardware supports it and verify download.
• “An installation step failed” during software install: Ensure network connection, skip extra software, or reinstall.
• VM resources insufficient: Increase allocated CPU cores, memory, and disk space.
• Incorrect ISO file: Always use official Kali ISO from the Kali.org website.
• Virtualization disabled: Enable VT-x/AMD-V in BIOS/UEFI settings.
• Secure Boot enabled: Disable Secure Boot as Kali kernel is unsigned.
• Sparse disk space: Allocate minimum 20 GB free disk space.
• Incompatible architecture: Confirm 32-bit vs 64-bit ISO matches hardware.
• Legacy boot vs UEFI conflicts: Adjust BIOS settings accordingly for installation.
• Desktop environment fails to load: Reinstall or switch to XFCE desktop environment.
• Missing peripheral drivers: Manually install firmware packages for network and graphics cards.
• Partitioning errors: Use guided partitioning unless experienced with manual setup.
• Corrupted VM Saved State: Discard saved state and restart VM.
• Root account disabled: Use new default non-root user “kali” and set passwords accordingly.
• Installation media not detected: Verify media integrity or remake USB/DVD boot media.
