GenesisOS 2.0

GenesisOS 2.0 is a Bare-metal Operating System made for daily use and weak computers, while also having a big overhaul from the first version.

Fun Facts

The name "Genesis" references the first chapter of the Bible, marking the beginning of my career.
GenesisOS was originally supposed to be called "Journey OS" and started out as a Linux distro.
