Installation of Opensuse 15.2 Leap in 10 Steps
Creating Installation Media
Download the system ISO from the following link https://software.opensuse.org/distributions/leap The screens shown will be based on the netinstall version. To create bootable media we recommend using Rufus https://rufus.ie/ To create bootable UEFI and BIOS media, after inserting a pendrive on an active USB port, use the following settings and finally press Start to start the creation of the installation media:
To boot from a USB medium, you may need to enable this option in the firmware; consult the manual of your PC or motherboard. Some examples:
|Brand||Model 2||One Time Boot Menu|
|Asus, AsRock||F2 or CANC||F8|
Starting the Installation Program
Initialization (Without Details)
If the installation status bar scrolls, but the installation seems to be stuck, press ESC to get details on what the installer is really doing
Initialization (With Details)
Here is an example: the program has loaded the drivers without encountering errors, has recognized the disk, the wired network card (necessary if you run the netinstall), has successfully contacted DHCP obtaining a basic network configuration and finally the installer was loaded in 6 steps.
Update (Netinstall only)
In some cases the netinstall shows this screen in order to update the boot image, you had to say YES (YES) and continue
System Language & Keyboard Mapping
Select the language for the operating system (where the menus and messages are written) and the keyboard mapping (depends on your configuration). It’s optional but, we recommend trying to type something in the Keyboard Check field to verify the correct loading of the chosen layout. At the end press Next
and choose (immediately after) to Activate Online Repositories
In this screen you can select the repository (that is software collections ). In order to perform a clean installation, is not recommend to add repositories; at most select the source repository (as shown). Once the selection is complete, press Next Wait for the completion (it can take a few tens of seconds) and at the end press Next
The choice is totally personal, but for an optimal experience we recommend KDE or alternatively GNOME . If you prefer other Desktop Environments, for example XFCE , LXQT , LXDE , Enlightenment …, choose Generic Desktop. In case you exactly know what to do, and you want to install some other window manager or desktop environment ( I3VM, sway, JWM, Deepin … ) choose Server. At the first reboot you can install all the necessary programs. Transactional Server is not recommended for music production. Once you have made your choice, press Next
Users inexperienced are advised to choose Advanced partitioning and Start with the current Proposal; after which it is recommended to set EXT4 instead of Btrfs.
intermediate users (for example those who have already graphically installed other Linux distro or those who want to install Opensuse in dual boot) are advised to Advanced Partitioning starting from existing partitions and for example, create the following layout:
|Partition||Minimum Dimensions||File System|
|SWAP||128 MiB - 12 GiB||Swap|
|ROOT||> 20 GiB||Ext4|
|HOME||> 20 GiB||Ext4|
Note on the Swap: in modern systems, with SSD or NVME disks, with 8 GB of RAM, the swap is almost useless, but it becomes essential for example on laptop if you plan to use the suspension. If in doubt, set the swap size to 12 GB.
Advanced users will be amused being able to define in a few clicks (without remembering long chains of commands) RAID, snapshots, mount options etc.
Advanced Partitioning (inexperienced users)
Select the root point with mount point / Choose Edit → Edit partition
Change the file system type from Btrfs to EXT4 Press Next
After making the changes, press I accept and then Next
Advanced Partitioning (intermediate and expert users)
After choosing start with the existing partitions you have the possibility to modify the disks listed in the box Space available on linux . Here you can create / recreate the partition table (acting on Modify → Create new partition table ) or create partitions acting on Partitions → Add partition . The system view pane contains the most advanced options, such as those for mounting an NFS volume, for creating a RAID etc.
Advanced Partitioning (partition creation)
It is possible to use all the available space or only a portion pf it; the unit of measurement can be modified. Unless you know exactly what you are doing, it is not recommended to edit the blocks . Blocks are related to disk geometry and creating partitions ignoring their structure can compromise performance and (in some cases) data loss. Make the desired selections press Next
Advanced Partitioning (mount points)
The selections on this screen define the mount points:
|Operating system||= /|
|Data and applications||= / home|
|EFI boot partition||= / boot / EFI|
|Volume raw||= unformatted|
Advanced Partitioning (fstab options)
Press fstab options to define for example the volume label (very useful in cases where multiple operating systems are installed on the same disk) Press Next after confirming the options

Installation Customization (Start)
By clicking on Start you can customize the settings of the boot loader . Normally nothing needs to be changed
Installation Customization (Start)
Installation customization (Network configuration 1/3)
Wicked is usually recommended for servers or fixed PCs; Opensuse's Reference manual suggests using NetworkManager for laptops or PCs where there are frequent network changes.
Installation customization (Network configuration 2/3)
Installation customization (Network configuration 3/3)
In this screen you can customize the host name and DNS . On the Routing screen you normally don't need to touch anything.
Installation Customization (Programs 1/4)
By clicking on Programs you can customize the collection of programs that will be installed on the system
Installation Customization (Programs 2/4)
The programs are organized in Models , that is a thematic collections of software. Only the selected models will be installed on the system. If you press Details you can view the contents of the selected model
Installation Customization (Programs 3/4)
Within the model you can select or deselect individual packages, view dependencies or technical data. After accepting the selected settings and confirming, the packet manager calculates the dependencies and proposes a summary. Normally you had to do nothing but accept.
