Grunty OS is a free OS Developed by GuntXProductions. It has a working filesystem , a 32 bit assembler that is still being developed, and a simple executable loader. If you want the current release then goto and click on snapshots. The current version (Infinity) is not open source at the moment (Some components are though , message me if you want them) , although it might be later.

Grunty OS was written in the C# Programming Language and assembly uses Cosmos a powerful project that lets you compile bootable C# code.
