Gentoo LiveCD Installer, RC4

A live USB image that installs Gentoo with a guided desktop wizard, or repairs a Gentoo system that does not start. It works on most 64-bit PCs and laptops.

This project is assisted by AI. AI coding agents wrote most of it, directed by the maintainer.

It is unofficial. It is not an official Gentoo release, and it is not made or endorsed by the Gentoo Foundation. Gentoo is a trademark of the Gentoo Foundation, Inc. and of Förderverein Gentoo e.V.

It is a release candidate. Install it only on a spare disk or a spare PC. An install erases the disk you choose. This build was tested in virtual machines, not yet on real hardware.

Before you start

  • Secure Boot on: the first start shows blue screens once, so that the PC learns the key of this disc. Enroll it only if the fingerprint matches the one below.
  • Installed system: it starts with GRUB, which is not signed. Turn Secure Boot off in the firmware settings before its first start.
  • Kernels: the disc runs Linux 7.2.13. Installs get the newest Gentoo distribution kernel.

was built: it can sign nothing else. Enroll it only when the fingerprint matches.
