MultiBoot USB
This is a project that contains a collection of GRUB files and scripts that will allow you to create a pendrive capable of booting different ISO files.
Antergos is a modern, elegant and powerful operating system based on Arch Linux. It started life under the name of Cinnarch, combining the Cinnamon desktop with the Arch Linux distribution, but the project has moved on from its original goals and now offers a choice of several desktops, including GNOME 3 (default), Cinnamon, Razor-qt and Xfce. Antergos also provides its own graphical installation program.
