The bootloader is GRUB. I haven't tested building TestKernel on anything but MS.NET, but you can give it a shot. Follow the instructions at the GitHub repo ( http://github.com/daeken/RenrakuOS/tree/master http://github.com/daeken/RenrakuOS/tree/master , also linked in my post), and if you're running on a non-Windows platform, you'll have to install nasm and point the build script to that instead of the exe that ships.
