User:Xerxeslins/Simplified Installation of Gentoo

This article is a summary for reference, which removes much of the information from the Handbook to meet a specific case: installing Gentoo using ext4 file system, Systemd, GRUB, GPT/UFI, no encryption, all system directories on a single partition (except for efi partition). It serves as a superficial guide and reminder of the installation process that can perhaps help you in some way. But if you want "generic" content that adapts to all situations, the best option would be to read the Handbook.

Article tested on a modest personal computer:


 * AMD Ryzen 7 3700X
 * 32 GB RAM SSD4
 * 128 GB NVMe SSD
 * GPU RADEON R5220 2 GB

Burn the ISO to a USB device and boot from it.
