The Quick Install guide covers the Gentoo install process in a non-verbose |
| 23 |
neysx |
1.52 |
manner. Its purpose is to allow users to perform a stage3 install in no time. |
| 24 |
|
|
Users should already have prior experience with installing Gentoo Linux if they |
| 25 |
|
|
want to follow this guide. |

This guide contains all the commands you should use to complete a stage3 |
| 42 |
neysx |
1.52 |
installation of Gentoo. You need a connection to the Internet to download the |
| 43 |
|
|
stage3 and Portage snapshots. |

New users should read the <uri link="/doc/en/handbook/index.xml">Handbook</uri> |

as it gives a better overview about the installation process. The Quick Install |

guide is designed for experienced users who just need a checklist to follow. |

Use <c>fdisk</c> or <c>cfdisk</c> to create your partition layout. You need at |
| 91 |
neysx |
1.52 |
least a swap partition (type 82) and one Linux partition (type 83). The |
| 92 |
neysx |
1.82 |
following scenario creates a <path>/boot</path>, a swap and a main partition as |
| 93 |
|
|
used in our handbook. Replace <path>sda</path> with your disk. Most systems |
| 94 |
|
|
ignore the bootable flag, but a few need it. Set this flag on your boot |
| 95 |
|
|
partition with fdisk's <c>a</c> command. |
