The netinst CD image is a popular image which can be used to install trixie 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 trixie system. If you'd rather, you can get a 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.

debian-installer можно загрузить полностью из сети. Методы загрузки по сети (netboot) зависят от архитектуры и настройки сетевой загрузки. Файлы для загрузки debian-installer по сети лежат в каталоге netboot/.

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 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.
