Preparations


  • Make bootable USB drive of Ubuntu 18.04 with the program GNOME Disk Utility (GNU/Linux) or Unetbootin (on Windows).
  • Make a new blank partition of 20GB at least.
  • Make a second blank partition of 1GB at least.
  • Backup your important data if you have another system (i.e. Windows) in the same coputer. If your computer is new/blank, then just go ahead.

Booting


Restart your computer to show your BIOS and change it to boot via USB. Plug your bootable USB drive of Ubuntu and restart to show the Ubuntu 18.04 screen. You will see two choices: Try Ubuntu and Install Ubuntu. Choose Try instead.
 

1. Select Language


Choose a language from the first page. The default choice is English and is safe.

First Step

2. Select Keyboard Layout


Choose the default choice of English (US), except you are using specific charset like Russian or Japanese keyboard. This step is what makes it different from previous Ubuntu version.

Second Step

3. Select No Network Connection


Choose "I don't want to connect to a wifi/network". This makes your installation faster. Anyway, you can still update & upgrade Ubuntu after installation finished.

Third Step

4. Select No Third-Party Software


Blank all choices on this step. The first blank choice makes the installation normal, not minimal. The second blank and the third greyed choice make installation faster and not need internet connection. This step is also an improvement compared to previous Ubuntu version.

Fourth Step

5. Select Something Else


Choose "Something Else" from Installation type step. This makes you manually partition your disk and not handing over your control to automatic installer. Do not select Install alongside, do not select Erase disk.

Fifth Step

6. Create Main Partition


First partitioning step: select your first blank partition > press Change button > fill it Use as: Ext4 journaling, Format the partition: yes (checked), Mount point: / > OK.

Sixth Step

7. Create Swap Partition


Second partitioning step: select your second blank partition > press Change button > fill it Use as: swap area > OK.

Seventh Step

8. Choose Bootloader Location


For example, if your main partition is /dev/sda6, then you choose location of Ubuntu's bootloader at /dev/sda. This means you choose the parent (the hard disk) sda of the main partition sda6 to place the bootloader. As simple as that.

Eighth Step

9. Start Installation


Read once again your partitions configuration to make it sure nothing wrong selected. Once you are sure, press Install Now. This starts the real installation process and you can not go back.

Ninth step

10. Enter User Information


You enter 2 kinds of information here:

Choose your geographical location (such as Jakarta, Indonesia):

10.1 Your Geolocation

Create your username & password:

10.2 Your Password

Notice that your geolocation determines your local time and your password there are the same as your sudo password later.

11. Wait


This is the last step of copying entire files into the new partition and setting up a new operating system. Wait until all processes finished. While processing, Ubuntu 18.04 will show you a slideshow presentation of its features. This last process should takes only 15 minutes or less.

Eleventh step

Installation Finished


Once finished, the installer tells that "Installation Complete" and "has finished". Press Restart Now and enjoy Ubuntu 18.04 LTS!
