Install SUSE\* Linux Enterprise Server 12 SP2

#############################################

|
This guide describes SUSE-specific details of the :ref:`multi-boot`
|
|
tutorial.
|
|
|
|
#. Start the SUSE installer and follow the prompts.
|
|
|
|
#. At the :guilabel:`Suggested Partitioning` screen, choose
|
|
:guilabel:`Expert Partitioner`. See Figure 1.

|
|
|
|
**Optional:** Under :guilabel:`Available Storage on Linux` section,
|
|
right-click the SUSE :file:`/home` partition and delete it. In this example, it is :file:`/dev/sda8`. See Figure 2.

|
|
|
|
#. Under :guilabel:`Available Storage on Linux` section, right-click the SUSE
|
|
root partition and resize it. In this example, :file:`/dev/sda7` is
|
|
resized to 45 GB. See Figure 3.

|
|
|
|
#. Click :guilabel:`Accept`.
|
|
|
|
#. Follow the remaining prompts to complete the SUSE installation.
|
|
|
|
#. At this point, you cannot boot |CL| because `Grub`
|
|
is the default boot loader. Follow these steps to make the |CL|
|
|
Systemd-Boot the default boot loader and add SUSE as a boot option:
|
|
|
|
#. Boot into SUSE.
|
|
|
|
#. Log in.
|
|
|
|
#. Locate the SUSE :file:`grub.cfg` file in the :file:`/boot/grub2/` directory
|
|
and look for the primary SUSE :guilabel:`menuentry` section. In Figure 4, the
|
|
highlighted lines identify the kernel, the :file:`initrd` filenames, the
|
|
root partition UUID, and the additional parameters used. Use this information
|
|
to create a new Systemd-Boot entry for SUSE.

#. Copy the kernel and the :file:`initrd` file to the EFI partition.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo cp /boot/vmlinuz-4.4.21-69-default /boot/efi
|
|
|
|
sudo cp /boot/initrd-4.4.21-69-default /boot/efi
|
|
|
|
#. Create a boot entry for SUSE. At a minimum, the file must contain
|
|
these settings:
|
|

|
|
| Setting | Description |
|

See the `systemd boot loader documentation`_ for additional
|
|
details.
|
|
|
|
The *options* parameter must specify the root partition UUID and
|
|
any additional parameters SUSE requires.
|
|
|
|
.. note:: The root partition UUID used below is unique to this example.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudoedit /boot/efi/loader/entries/suse.conf
|
|
|
|
Add the following lines to the :file:`suse.conf` file:
|
|
|
|
.. code-block:: console
|
|
|
|
title SUSE Linux Enterprise 12 SP2
|
|
|

|
|

|
|
#. Re-install Systemd-Boot to make it the default boot loader.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo bootctl install --path /boot/efi
|
|
|
|
.. note::
|
|
If an older version of SUSE does not have the `bootctl` command,
|
|
skip this step and see :ref:`multi-boot-restore-bl` to restore
|
|
Systemd-Boot.
|
|
|
|
#. Reboot.
|
|
|
|
If you want to install other :abbr:`OSes (operating systems)`, refer to
|
|
:ref:`multi-boot` for details.
