A.2. インストーラを起動する

For some quick links to installation images, check out the debian-installer home page. The debian-cd team provides builds of installation images using debian-installer on the Debian CD/DVD page. For more information on where to get installation images, see 「Official Debian GNU/Linux installation images」.

Some installation methods require other images than those for optical media. The debian-installer home page has links to other images. 「Where to Find Installation Files」 explains how to find images on Debian mirrors.


A.2.1. Optical disc

The netinst CD image is a popular image which can be used to install bullseye with the debian-installer. This installation method is intended to boot from the image and install additional packages over a network; hence the name netinst. The image has the software components needed to run the installer and the base packages to provide a minimal bullseye system. If you'd rather, you can get a full size CD/DVD image which will not need the network to install. You only need the first image of such set.

Download whichever type you prefer and burn it to an optical disc.

A.2.2. USB メモリ

取り外し可能な USB 記憶装置からもインストールできます。例えば、USB メモリは、どんな場所ででも手軽に Debian をインストールできる媒体です。

The easiest way to prepare your USB memory stick is to download any Debian CD or DVD image that will fit on it, and write the image directly to the memory stick. Of course this will destroy anything already on the stick. This works because Debian CD/DVD images are isohybrid images that can boot both from optical and USB drives.

その他にも、debian-installer で使用するための USB メモリを設定する、より柔軟な方法があり、もっと小さなサイズの USB メモリで動作させられます。詳細は、「USB メモリでの起動用ファイルの準備」をご覧ください。

A.2.3. ネットワークからの起動

debian-installer をネットから完全に起動することもできます。netboot のための様々な方法は、アーキテクチャや netboot の設定に依存します。netboot/ 以下のファイルは、debian-installer を netboot するために使用できます。

A.2.4. ハードディスクからの起動

It's possible to boot the installer using no removable media, but just an existing hard disk, which can have a different OS on it. Download hd-media/initrd.gz, hd-media/vmlinuz, and a Debian CD/DVD image to the top-level directory of the hard disk. Make sure that the image has a filename ending in .iso. Now it's just a matter of booting linux with the initrd.
