Insert the openSUSE Leap DVD into the drive, then reboot the computer to start the installation program. On machines with a traditional BIOS you will see the graphical boot screen shown below. On machines equipped with UEFI, a slightly different boot screen is used. Secure boot on UEFI machines is supported.

Use F2 to change the language for the installer. A corresponding keyboard layout is chosen automatically. See Section 2.2.1.1, “The Boot Screen on Machines Equipped with Traditional BIOS” or Section 2.2.1.2, “The Boot Screen on Machines Equipped with UEFI” for more information about changing boot options.

Select Installation on the boot screen, then press Enter. This boots the system and loads the openSUSE Leap installer.

The Language and Keyboard Layout are initialized with the language settings you have chosen on the boot screen. Change them here, if necessary.

Read the License Agreement. It is presented in the language you have chosen on the boot screen. License Translations are available. Proceed with Next.

In case no network interface could be configured automatically via DHCP, the Network Settings dialog opens. If you prefer to install openSUSE Leap with no network connection, choose Next to proceed. However, configuring the network at this stage is recommended, since it will allow to install the latest updates and security fixes from the online update repository. A working network connection will also give you access to additional software repositories. This step is skipped if a network interface was successfully configured via DHCP.

To configure the network, choose a network interface from the list and click Edit to change its settings. Use the tabs to configure DNS and routing. See Book “Reference”, Chapter 13 “Basic Networking”, Section 13.4 “Configuring a Network Connection with YaST” for more details.

A system analysis is performed, where the installer probes for storage devices, and tries to find other installed systems. When the analasys has finished, the Installation Options screen launches.

You have got two choices:

Tip: Release Notes

From this point on, the Release Notes can be viewed from any screen during the installation process by selecting Release Notes.

Review the partition setup proposed by the system. If necessary, change it. You have the following options:

To accept the proposed setup without any changes, choose Next to proceed.

Select the clock and time zone to use in your system. To manually adjust the time or to configure an NTP server for time synchronization, choose Other Settings. See Section 2.8, “Clock and Time Zone” for detailed information. Proceed with Next.

If you have selected Add Online Repositories Before Installation earlier during the installation, the List of Online Repositories screen lets you choose which official openSUSE Leap online repositories to add. The default selection is the recommended choice. In case you would also like to have the repository hosting the sources for the complete distribution, add Main Repository (Sources). The Debug repositories as well as the Untested Updates are for experts and beta testers only.

After having proceeded with Next, you need to confirm the license agreement for the online repositories with Next.

If you have selected Include Add-On Products from Separate Media earlier during the installation, the Add-On Product step lets you add addtitional repositories.

Activate I would like to install an additional Add-On Product. Specify a media type, a local path or a network resource hosting the repository and follow the on-screen instructions.

Check Download Repository Description Files to download the files describing the repository now. If deactivated, they will be downloaded after the installation has started. Proceed with Next and insert a medium if required. Depending on the product's content it may be necessary to accept additional license agreements. Proceed with Next. Add-On products can also be installed at any time later from the running system as described in Chapter 10, Installing Add-On Products.

Note: The Add-On Product Installation Screen

In case you have also configured the product online repositories, you will not see the screen depicted in the screensjot above, but rather a table showing the products online repositories that already have been added. Choose Add to advance to the Add-On Product screen.

Select the desktop system you would like to use. KDE and GNOME are among the most widely used desktops on Linux. If you prefer a different desktop, choose Other for more options. The XFCE Desktop and the LXDE Desktop are fast and lightweight desktop environments suitable for modest hardware. With Minimal X Window, install a graphical window manager that allows for running stand-alone X applications and console windows but does not provide the usual integrated desktop functionality. In Minimal Server Selection (Text Mode), only console terminals are available.

To create a local user, type the first and last name in the User’s Full Name field, the login name in the Username field, and the password in the Password field.

The password should be at least eight characters long and should contain both uppercase and lowercase letters and numbers. The maximum length for passwords is 72 characters, and passwords are case-sensitive.

For security reasons it is also strongly recommended not to enable the Automatic Login. You should also not Use this Password for the System Administrator but rather provide a separate root password in the next installation step. Mails generated by the system are delivered to the user root by default. Check Receive System Mail if you would rather get them as the user that you have created.

Selecting Change gets you to the expert options explained in Chapter 3, Managing Users with YaST. Proceed with Next.

Type a password for the system administrator account (called the root user). This step is skipped if you have chosen Use this Password for the System Administrator in the previous step.

You should never forget the root password! After you entered it here, the password cannot be retrieved. See Section 2.13, “Password for the System Administrator root” for more information. Proceed with Next.

Tip: Passwords and Keyboard Layout

It is recommended to only use characters that are available on an English keyboard. In case of a system error or when you need to start your system in rescue mode a localized keyboard might not be available.

Use the Installation Settings screen to review and—if necessary—change several proposed installation settings. The current configuration is listed for each setting. To change it, click the headline. Some settings, such as firewall or SSH can directly be changed by clicking the respective links.

Tip: Remote Access

Changes you can make here, can also be made later at any time from the installed system. However, if you need remote access directly after the installation, you should adjust the Firewall and SSH settings by opening the SSH port and enablöing the SSH server.

After you have finalized the system configuration on the Installation Settings screen, click Install. Depending on your software selection you may need to agree to license agreements before the installation confirmation screen pops up. Up to this point no changes have been made to your system. After you click Install a second time, the installation process starts.

During the installation, the progress is shown in detail on the Performing Installation screen.

After the installation routine has finished, the computer is rebooted into the installed system. Log in and start YaST to fine-tune the system. If you are not using a graphical desktop or are working from remote, refer to Book “Reference”, Chapter 1 “YaST in Text Mode” for information on using YaST from a terminal.
