rEFInd is a simplistic boot manager for UEFI-based systems. This is a clean, dark and cute theme for it.

How to install BlackCatMuzzle-rEFInd

BlackCatMuzzle-rEFInd installs like any rEFInd theme: clone it into rEFInd's themes folder and include it from refind.conf.

Where is refind.conf? On Linux it's usually /boot/efi/EFI/refind/refind.conf. On macOS and Windows, mount the EFI System Partition first; open the help dialog ( in the header) for every path.

  1. Locate the themes/ folder

    It lives inside your rEFInd installation directory. If it doesn't exist, create it:

    mkdir -p /boot/efi/EFI/refind/themes
  2. Download the theme

    Clone the theme's GitHub repository into that folder, or extract its ZIP archive:

    git clone https://github.com/Scorpi-ON/BlackCatMuzzle-rEFInd.git /boot/efi/EFI/refind/themes/BlackCatMuzzle-rEFInd
  3. Edit refind.conf

    With administrator privileges, add this line at the very bottom:

    include themes/BlackCatMuzzle-rEFInd/theme.conf

    If the repository keeps theme.conf in a subfolder, adjust the path to match.

  4. Save and reboot

    rEFInd will render the new theme on your next boot.

Where is refind.conf?

The location depends on your operating system:

  • Linux: /boot/efi/EFI/refind/refind.conf or /boot/EFI/refind/refind.conf
  • macOS: /Volumes/ESP/EFI/refind/refind.conf (mount the EFI System Partition first)
  • Windows: S:\EFI\refind\refind.conf (after mounting the ESP to drive S: as Administrator)

Can I customize OS icons and backgrounds?

Yes. rEFInd themes define custom graphics for operating system icons (Linux, Windows, macOS, Arch, Ubuntu, etc.), tool icons (reboot, shutdown, firmware), selection highlights, and banner backgrounds. Swap or edit any .png file inside the theme's directory to suit your preferences.

What is rEFInd?

rEFInd is an advanced, open-source UEFI boot manager maintained by Rod Smith. Designed for systems that dual-boot or multi-boot, such as Linux distributions (Ubuntu, Arch, Fedora), macOS, and Windows, it offers a clean, visual alternative to text-only bootloaders like GRUB.
