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.

Det er også muligt at installere fra eksterne USB-lagerenheder. For eksempel et USB-drev være et smart Debian-installationsmedie, som du kan medtage overalt.

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.

Der er andre, mere fleksible måder at opsætte et hukommelsesdrev for debian-installer, og det er muligt at få den til at fungere med små hukommelsesdrev. For detaljer se Afsnit 4.3, “Forberedning af filer for opstart via USB-hukommelsesdrev”.

Det er også muligt at starte debian-installer alene fra nettet. De forskellige metoder til netopstart afhænger af din arkitektur og opsætning af netopstarten. Filerne i netboot/ kan bruges til at netopstarte debian-installer.

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.
