Grub2Win

Grub2Win is a robust, free, and open-source Windows application that allows you to safely multiboot Windows and Linux systems. Configure your Grub boot screen and options directly from Windows without complex procedures. All modules are SSL signed for your security. The software installs entirely to a compact 30 MB directory on your C: drive. You can personalize the boot menu by using your own JPG files as custom background wallpaper. It automatically generates configuration files for a wide range of systems including PhoenixOS, Android, Ubuntu, Debian, Suse, Fedora, Manjaro, Mint, OpenCore, POSROG, and Windows, and supports importing configs for Chrome OS and other distributions.
