Verify integrity of the file.iso that you downloaded before creating live USB drive.

Note that you can use software that has GUI (Graphical User Interface) such as 'HashTab', 'GtkHash' instead of using command line in Terminal window.

Live USB Drive

Note that after creating live USB, you can install Lubuntu on a computer that already has OS (Operating System)
without resizing or creating a new partition by yourself because the live USB drive can detect the old OS and find empty space on your harddisk.

without resizing or creating a new partition by yourself because live USB drive can detect the old OS and find empty space on your harddisk.

--------------------------------------------

TestDisk

Note that if you have installed Linux successfully, you can skip this topic.
Actually you can install Lubuntu with live USB drive without resizing a partition or creating a new partition by yourself.
In case you try resizing a partition or creating a new partition by yourself, but it fails
, and you need to copy file from unallocate partition to a flashdrive or an external harddisk.
You should use only the following keys or commands.
p=list, :=select file, C=copy, arrow key=change directory, C=paste in destination directory in the flashdrive or an external harddisk
, and then use q=quit when you want to go back to the previous menu.
If you want to exit, you just hold down or press 'q' key many times until you exit especially when you are unsure what you just did.
Do not write any partitions because the parition that has D=Delete charatecristic will be unallocate partition when you boot your computer again next time.
You need to write (BackupBS, *=boot charatecristic) only if you try to boot from the partition that has problem, but that might take a long time.

GRUB

Note that in case there is something wrong e.g. you play with partitions and your Linux cannot boot anymore
, so you need to rescue GRUB to make your Linux be able to boot again.

Most Used Linux Terminal Commands

Note that you can use 'Ctrl+Alt+T' or use menu 'System>Tools>LXTerminal' to open a Terminal window at the 'Home' directory.
You can also open a Terminal window at a directory by right clicking at the directory, and then selecting 'Open in Terminal' from the pop-up menu.
When you want to copy a long text command e.g. the long command from a web page when installing a software
, you need to use 'Copy' and 'Paste' from the pop-up menu by right clicking at that long command
because you cannot use Ctrl+C and Ctrl+V in the Terminal.

How to install font

Note that if you want to install by copying file.ttf to home/computername/.fonts directly
, you need to use 'View>Show Hidden' to show the '.fonts' directory
, but it is easier if you use software that has GUI (Graphical User Interface) like 'Font Manager' instead.

Unalbe to log in because the keyboard cannot work

Some users cannot log in after updating the latest of Linux via the internet.
If you have this problem, you need to download and install files via the internet.
If you share the internet by using your smartphone via the USB port
, you need to insert the USB cable after you select 'kernel (recovery mode)' menu
and before you select 'Network' menu of the GRUB.
You cannot insert USB cable before you boot your computer because when your computer boots
, your smartphone will reset or turn off the internet sharing via the USB port automatically.
In other words, insert the USB cable, then open internet sharing at your smartphone
, and then select 'Network' menu of the GRUB.
Note that the following links will show you how to download and install the files.
