Setting up partitions
|
|
---------------------
|
|
|

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 choose to use a swap file under :guilabel:`Erase disk` keep :menuselection:`Swap to file` or to not use swap choose :menuselection:`No Swap`. If you want to encrypt your drive press the :guilabel:`Encrypt system` checkbox and then you will need to enter the encryption passphrase twice make sure you have it typed in correctly. It is strongly advised to write down this passphrase and keep it somewhere safe.

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

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

|
|
sudo swapoff -a
|
|
|
|
which will unmount them and any swap partitions. 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.

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.

|
|
|
|
.. Warning::
|
|
Creating a new partition table will erase all data on the drive and deleting a partion will delete all data on the partition.
|
|
|
|
If you have a new hard disc 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 disc 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.

|
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.
