Chapter 1.3 Installation
========================
This is a guide through the installation process of Lubuntu.

Starting the installer
----------------------

At the start of the boot process, a GRUB splash screen will be shown. To install select :menuselection:`Try or Install Lubuntu`. If you have a problematic graphics card, select :menuselection:`Lubuntu (safe graphics)` (for example, some NVIDIA cards will need this.) To test your RAM, select :menuselection:`Test memory`.

.. image::  grubsplash.png

The next screen will present a choice between :guilabel:`Try Lubuntu`, which will give you a live session to run Lubuntu as you see fit, or run the installer directly with :guilabel:`Install Lubuntu`. Above this there is a field to select which language you want to install in the :guilabel:`Select Your Language` drop down. To get this screen in your language, select one then press the :guilabel:`Confirm` button. If you need more advanced network settings to install Lubuntu than just connecting to Wi-Fi use the :guilabel:`Try Lubuntu` choice. If choose :guilabel:`Install Lubuntu` the installer will start right away and install in your language. At the bottom of your screen if you are connected to the internet automatically like with an Ethernet cable it will say :guilabel:`Connected` at the bottom. If you are not connected to the internet at the bottom it will say :guilabel:`Not Connected`.

Setting Up Partitions
---------------------

If all you want is Lubuntu on your machine, you can select the :guilabel:`Erase disk` button. This will format the disk and **delete all data on the disk**,  which is why having your data backed up before this point is extremely important. If you choose to do this you can continue on to user setup. To change the storage device to install Lubuntu on use the :guilabel:`Select Storage device` drop down menu. To see whether you are installing in uefi or bios mode is shown in the top left corner of this window. To choose to use a swap file under :guilabel:`Erase disk` keep :menuselection:`Swap to file` or to not use swap choose :menuselection:`No Swap`. To choose which filesystem to use the drop down on the right to choose which filesystem you want to use. If you want to encrypt your drive press the :guilabel:`Encrypt system` checkbox and then you will need to enter the encryption passphrase twice to make sure you have it typed in correctly. It is strongly advised to write down this passphrase and keep it somewhere safe. 

.. warning::
   Erasing your entire disk or partition may cause you to lose data so please backup beforehand.

.. image:: partitioning.png 


.. note:: 
   If you had a previous Linux install with a swap partition you will need to unmount the swap. To do this run 
.. code:: 

   sudo swapoff -a; sudo swapon /dev/zram0
  
which will unmount them and any swap partitions while still leaving zram enabled. This will not work if you have data partition mounted open PCManFM-Qt and press the upward pointed arrow on each partition in the :guilabel:`Places` sidebar to unmount all data partitions. 

To move back to Selecting your keyboard layout press the :guilabel:`Back` button. To advance to the setting up users press the :guilabel:`Next` button.

User Setup
----------
The user setup section creates a user profile, consisting of typing your name into the :guilabel:`What is your name?` field. Next type your username in the :guilabel:`What name do you want to use to log in?`. Put what you want your hostname of your computer to be in the :guilabel:`what is the name of this computer?` field. The last thing you need to enter is your password in the :guilabel:`Choose a password to keep your account safe`. Enter your password twice to make sure you have not mistyped it. To the right of your password will have an x if your passwords don't match. If you have a weak password to the right will have an orange triangle saying why your password is weak. Passwords less than 8 characters, containing a sequence like 1234, or based off a simple dictionary word like testing1 are considered weak. If a name can actually be used as a username or hostname a green checkmark will appear to the right of it if you cannot a red x will appear. Pressing the :guilabel:`Next` button will give you a summary screen, showing you the settings before the install begins.

Manual Partitioning
-----------------------
.. Warning::
   Trying to use nonlinux filesystems such as NTFS or FAT as your root filesystem will result in a broken system.

If you wish to manual set up partitions, as an advanced option you will have to choose which file-system you want. A file-system controls how your files are accessed at lower levels on the disk. If you are booting your computer in UEFI mode a more modern firmware compared to BIOS you will need to create an EFI system partition (see `efi system partition Wikipedia <https://en.wikipedia.org/wiki/EFI_System_partition>`_ for more detail). To create this partition you will need a FAT32 file-system with the ESP flag to be mounted at /boot/efi/ under the mount point. You will also need a root (/) file-system, several file-systems included for Lubuntu are Ext4, XFS, and Btrfs. Lubuntu 22.04 has bug with installing BTRFS and `This guide on Lubuntu discourse <https://discourse.lubuntu.me/t/getting-lubuntu-22-04-to-install-with-btrfs/3273/>`_

.. image:: manpartitioning.png

.. Warning::
    Creating a new partition table will erase all data on the drive and deleting a partition will delete all data on the partition.

If you have a new hard disk or solid state drive press the :guilabel:`New Partition table` button but this will delete the whole disc if you have any data on it. After pressing this button you will get a dialog saying what kind of partition table to use. The :guilabel:`Master Boot Record` button will create an old partition table but will only allow 4 primary partitions and partitions up to 2 Terabytes. The :guilabel:`GUID Partition Table` button works for large discs but may not be recognized by legacy operating systems. To get back to your main partitioning window press the :guilabel:`OK` button.

To change what disk you are partitioning use the :guilabel:`Storage device` drop down menu.

You can create partition by clicking the :guilabel:`Create` button which will bring up a dialog. The file system field is a drop down menu, select which file-system you want. You also need to select where you want to mount the partition in the :guilabel:`Mount Point` drop down menu. To change how big to make the partition change the :guilabel:`Size` field. To change the size or type of a partition after initially creating it press the :guilabel:`Edit` button. To delete a partition press the :guilabel:`Delete` button. You will need at least one root (/) partition and if you are booting an EFI system you will also need a /boot/efi mounted partition. Another common option is to have all your data on its own partition, which can even be on its own separate physical disk this can be mounted at /home. If you want to encrypt your your filesystem check the :guilabel:`Encrypt` checkbox. Then two fields will appear to get write type your encryption passphrase twice to confirm it. To add a label for this partition enter it into the :guilabel:`FS Label` field.

.. image::  manpartition-create.png

Lubuntu's bootloader grub does not support creating an encrypted / partition without a separate unencrypted /boot partition. If you create a separate /home partition will be where you save all your user documents photos and videos so make sure if you create one it has enough space for your personal files. All partitions created do not be on the same drive so you can for example put /home on its own drive to give you lots of space and then put / where all of your system and programs will be launched from. A good example of a sensible way to use manual partitioning is if you have a solid state disk and a hard drive in a computer, put the / partition on the solid state drive for faster program launches and /home on the hard drive for more space for your files. 

To go back on all your changes to the previous state press the :guilabel:`Revert All Changes` button in the top right. To change what device your computer will boot off of you will need to use the :guilabel:`Install boot loader on` drop down menu to select which disc to boot off of. 

In the center of the manual partitioning window shows you what name of the partition is. What type of filesystem is displayed in the :guilabel:`File System` column. To see where your partition is mounted are shown in the :guilabel:`Mount Point` column. The size of the system is shown in the :guilabel:`Size` Column.

The top of the manual partitioning window shows a visual bar showing size of your partitions on top. Below it shows each partition on your drive with the color it is in the bar graph and the size of the partition.


OEM Installs
------------

To install Lubuntu in an OEM mode for distributing to someone else on the grub boot splash select :menuselection:`OEM install (for manufacturers)` or from the panel menu :menuselection:`System Tools --> Install Lubuntu 24.10 (OEM mode)`. Then you will be asked if you are sure you want to install in OEM mode and to actually install in OEM mode press the :guilabel:`Yes` button. Then the installer will say have a welcome screen that will say it is in OEM mode will show up. To change what language to use for installation use the drop down bar under :guilabel:`OEM installation mode`. To move to the next step of installation press the :guilabel:`Next` button.
