Once the installer starts, you will be greeted with an initial screen. Press Enter to boot, or read the instructions for other boot methods and parameters (see Del 5.3, «Boot Parameters»).
After a while you will be asked to select your language. Use the arrow keys to pick a language and press Enter to continue. Next you'll be asked to select your country, with the choices including countries where your language is spoken. If it's not on the short list, a list of all the countries in the world is available.
You may be asked to confirm your keyboard layout. Choose the default unless you know better.
Now sit back while debian-installer detects some of your hardware, and loads the rest of the installation image.
Next the installer will try to detect your network hardware and set up networking by DHCP. If you are not on a network or do not have DHCP, you will be given the opportunity to configure the network manually.
Setting up the network is followed by the creation of user accounts. By default you are asked to provide a password for the «root» (administrator) account and information necessary to create one regular user account. If you do not specify a password for the «root» user, this account will be disabled but the sudo package will be installed later to enable administrative tasks to be carried out on the new system. By default, the first user created on the system will be allowed to use the sudo command to become root.
The next step is setting up your clock and time zone. The installer will try to contact a time server on the Internet to ensure the clock is set correctly. The time zone is based on the country selected earlier and the installer will only ask to select one if a country has multiple zones.
Now it is time to partition your disks. First you will be given the opportunity to automatically partition either an entire drive, or available free space on a drive (see Del 220.127.116.11, «Guided Partitioning»). This is recommended for new users or anyone in a hurry. If you do not want to autopartition, choose from the menu.
If you have an existing DOS or Windows partition that you want to preserve, be very careful with automatic partitioning. If you choose manual partitioning, you can use the installer to resize existing FAT or NTFS partitions to create room for the Debian install: simply select the partition and specify its new size.
On the next screen you will see your partition table, how the partitions will be formatted, and where they will be mounted. Select a partition to modify or delete it. If you did automatic partitioning, you should just be able to choose
/. For more detailed information on how to use the partitioner, please refer to Del 6.3.4, «Partitioning and Mount Point Selection»; the appendix Tillegg C, Partitioning for Debian has more general information about partitioning.
debian-installer formats your partitions and starts to install the base system, which can take a while. That is followed by installing a kernel.
The base system that was installed earlier is a working, but very minimal installation. To make the system more functional the next step allows you to install additional packages by selecting tasks. Before packages can be installed
apt needs to be configured as that defines from where the packages will be retrieved. The «Standard system» task will be selected by default and should normally be installed. Select the «Desktop environment» task if you would like to have a graphical desktop after the installation. See Del 18.104.22.168, «Selecting and Installing Software» for additional information about this step.
The last step is to install a boot loader. If the installer detects other operating systems on your computer, it will add them to the boot menu and let you know. By default GRUB will be installed to the UEFI partition/boot record of the primary drive, which is generally a good choice. You'll be given the opportunity to override that choice and install it elsewhere.
debian-installer will now tell you that the installation has finished. Remove the cdrom or other boot media and hit Enter to reboot your machine. It should boot up into the newly installed system and allow you to log in. This is explained in Kapittel 7, Booting Into Your New Debian System.
