This guide describes Ubuntu-specific details of the :ref:`multi-boot`
|
|
tutorial.
|
|
|
|
#. Start the Ubuntu installer and follow the prompts.
|
|
|
|
#. At the :guilabel:`Installation type` screen, choose
|
|
:guilabel:`Something else`. See Figure 1.

|
Figure 1: Ubuntu: Installation type.
|
|
|
|
#. Create a new root partition.
|
|
|
|
#. Under the :guilabel:`Device` column, select :guilabel:`free space`. See
|
|
Figure 2.

|
Figure 2: Ubuntu: Add partition.
|
|
|
|
#. Click the :guilabel:`+` button on the lower left corner.
|
|
|
|
#. Enter the new partition size. For this example, we used *40000 MB*, as
|
|
shown in Figure 3.

Figure 3: Ubuntu: Configure new root partition.
|
|
|
|
#. Set :guilabel:`Use as` to :guilabel:`Ext4 journaling file system`.
|
|
|
|
#. Set the :guilabel:`Mount point` to `/`.
|
|
|
|
#. Click :guilabel:`OK`.
|
|
|
|
#. Under the :guilabel:`Format?` column, select the new partition to be
|
|
formatted, in this example :file:`/dev/sda8`.
|
|
|
|
#. Share the swap partition that was created by |CL|.
|
|
|
|
#. Under the :guilabel:`Device` column, select :file:`/dev/sda2`.
|
|
|
|
#. Click :guilabel:`Change`.
|
|
|
|
#. Confirm :guilabel:`Use as` is set to :guilabel:`swap area`. See Figure 4.

|
|
|
|
#. Follow the remaining prompts to complete the Ubuntu 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 Ubuntu as a boot option:
|
|
|
|
#. Boot into Ubuntu.
|
|
|
|
#. Log in.
|
|
|
|
#. Locate the Ubuntu :file:`grub.cfg` file in the :file:`/boot/grub/`
|
|
directory and look for the :guilabel:`menuentry` section. In Figure 5, the
|
|
highlighted lines identify the kernel, the :file:`initrd` files, the
|
|
root partition UUID, and the additional parameters used. Use this
|
|
information to create a new Systemd-Boot entry for Ubuntu.

|
|
|
|
#. Copy the kernel and the :file:`initrd` file to the EFI partition.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo cp /boot/vmlinuz-4.8.0-36-generic.efi.signed /boot/efi
|
|
|
|
sudo cp /boot/initrd.img-4.8.0-36-generic /boot/efi
|
|
|
|
#. Create a boot entry for Ubuntu. At a minimum, the file must contain
|
|
these settings:
|
|
|
|
+---------+------------------------------------+
|
|
| Setting | Description |
|
|
+=========+====================================+
|
|
| title | Text to show in the boot menu |
|
|
+---------+------------------------------------+
|
|
| linux | Linux kernel image |
|
|
+---------+------------------------------------+
|
|
| initrd | initramfs image |
|
|
+---------+------------------------------------+
|
|
| options | Options to pass to the EFI program |
|
|
| | or kernel boot parameters |
|
|
+---------+------------------------------------+
|
|
|
|
See the `systemd boot loader documentation`_ for additional
|
|
details.
|
|
|
|
The *options* parameters must specify the root partition UUID and
|
|
any additional parameters that Ubuntu requires.
|
|
|
|
.. note:: The root partition UUID used below is unique to this example.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudoedit /boot/efi/loader/entries/ubuntu.conf
|
|
|
|
Add the following lines to the :file:`ubuntu.conf` file:
|
|
|
|
.. code-block:: console
|
|
|
|
title Ubuntu 16.04 LTS Desktop
|
|
|
|
linux /vmlinuz-4.8.0-36-generic.efi.signed
|
|
|
|
initrd /initrd.img-4.8.0-36-generic
|
|
|
|
options root=UUID=17f0aa66-3467-4f99-b92c-8b2cea1045aa ro
|
|
|
|
#. 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 Ubuntu 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.
