The Check disk for defects option offers a way to check integrity of the disk image once it is burned to the media please use this if you have problems installing it could be bad media. The Test Memory options test to make sure your RAM works on your computer.


Once you have booted into the live session, feel free to explore Lubuntu and make sure all your hardware works. Once you are ready to install Lubuntu, double click the icon in the top-left corner of the desktop Install Lubuntu 19.04.

Setting up partitions

If all you want is Lubuntu on your machine, you can select the Erase disk button.

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



If you have had a previous Linux install and want to put the entire disk or just replace an entire partition you will need to unmount them.

sudo swapoff -a

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 the Places sidebar to unmount all data partitions.

The Lubuntu installer provides some useful information while the installer is running. Once Lubuntu is installed you have a checkbox Reboot now after your Lubuntu is installed and is now finished.


Manual partitioning

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 for more detail to create this partition you will need a FAT32 file-system with the ESP flag with 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.


If you have a new hard disc or solid state drive press the 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 Master Boot Record button will create an old partition table but will only allow 4 primary partitions and partitions up to 2 Terabytes. The GUID Partition Table button works for large discs but may not be recognized by legacy other operating systems. To get back to your main partitioning window press the OK button.

To change what disc you are partioning use the Storage device drop down menu.

You can create partition by clicking the 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 Mount Point drop down menu. To change how big to make the partition change the Size field. To change the size or type of a partition after initially creating it press the Edit button. To delete a partition press the 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 press the Encrypt checkbox. Then a two fields will appear to get write type your encryption passphrase twice to confirm it.


To go back on all your changes to the previous state press the Revert All Changes button. To change what device your computer will boot off of you will need to use the 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 File System column. To see where your partition is mounted are shown in the Mount Point column. The size of the system is shown in the Size Column.
