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.

Είναι δυνατόν να εκκινήσετε τον debian-installer απευθείας από το δίκτυο. Οι διάφορες μέθοδοι για αυτήν τη διαδικασία εξαρτώνται από την αρχιτεκτονική του υπολογιστή και τη ρύθμιση του netboot (συντ. "Δικτυακή Εκκίνηση"). Τα αρχεία στον κατάλογο netboot/ μπορούν να χρησιμοποιηθούν για δικτυακή εκκίνηση του 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.
