Install x86_64 ArchLinux (late 2020)

How to Install x86_64 Arch Linux 2020 (Single Boot)

Pre-Installation

  • Set the keyboard layout and Font

    The default console keymap is US. To list available layouts, run ls /usr/share/kbd/keymaps/**/*.map.gz. To modify the layout, append a corresponding file name to loadkeys, omitting path and file extension.

    For example, run loadkeys jp106 to set a Japanese keyboard layout.
