The download is an .iso file. You can use it to create a bootable USB drive.

3. Save the file to a location of your choice.

Note: If you’re installing to a virtual machine (like VirtualBox), you can mount the .iso image directly.

Step 2: Create Bootable USB

You will need a USB drive with 4GB or more. This process will delete all data on the USB drive. Make sure to backup any existing data on the USB drive.

Option 1: Create a Bootable USB Drive on Ubuntu

Use the Create startup disk tool:

  1. Open a search dialog, and type create startup.
  2. If it’s not installed, the Software Center will offer the option to install it – choose the option for USB drive, then open the utility.
  3. In the top pane, click Other, then browse and select the Ubuntu 20.04 .iso file you downloaded.
  4. In the bottom pane, select your USB drive.
  5. Click Make startup disk.

Option 2: Create Bootable USB Drive on Windows

You’ll need to install a third-party utility called Rufus to create a USB bootable drive.

1. Download the Rufus utility. Scroll down to the download section and click the link to download the latest version of Rufus.

5. Click Start.

Step 3: Boot up Ubuntu from USB

1. Turn off your system. Make sure you remove all other USB devices, such as printers, memory cards, etc.

2. Insert the Ubuntu USB drive into the system and turn on your machine.

There are two possible scenarios:

  • The computer boots the USB drive automatically.
  • You need to manually configure USB booting in the Boot Menu or BIOS/UEFI.

3. To manually configure the boot order, tap the boot menu key about once or twice per second as soon as the computer powers on.

The boot menu key may be different depending on your computer manufacturer. Below is a list of common boot keys associated to a brand:

Asus F8 or Esc
Acer F12F9 or Esc
Compaq F9 or Esc
Dell F12
eMachines F12
Fujitsu F12
HP F9 or Esc
Lenovo F8F10 or F12
Samsung F2F12 or Esc
Toshiba F12

4. Once you see your boot menu, use the arrows to pick the Ubuntu media to boot from. For a DVD, the entry will usually have DVD or Optical in the name. USB is usually labeled USB.

Your system should start loading the Ubuntu live disc menu.

Step 4: Run Ubuntu

You can test Ubuntu 20.04 before you commit to installing it. The .iso includes a live mode that only runs in memory.

Launch this mode by clicking Try Ubuntu.

Try Ubuntu 20.04.

Step 5: Install Ubuntu 20.04 LTS Desktop

To begin the installation, click Install Ubuntu.

Install Ubuntu 20.04.

Choose Keyboard Layout

By default, the system will select English and English.

If you have a non-standard keyboard, you can select it in the list. Alternately, click Detect Keyboard Layout and the system will automatically choose your keyboard. If you need to test your keyboard, use the labeled field.

When you’re ready, click Continue.

Choose keyboard layout for Ubuntu 20.04.

Choose Starting Applications

  • Normal Installation – This is the full Ubuntu Desktop experience, with office software, games, and media players.
  • Minimal Installation – Choose this to save disk space, especially if you won’t be using media players or productivity software.

You’ll also be asked to confirm other options:

  • Download updates while installing Ubuntu – This does the work of downloading large package files during the installation. Once the installation finishes, the packages will be ready to apply as updates.
  • Install third-party software for graphics and Wi-Fi hardware and additional media formats – Some hardware, like graphics cards and wi-fi cards, do not have open-source driver support. Also, some media formats, such as .wmv, do not fall under the GPL license. If you need support for these, you’ll need to agree to additional terms of use.
Choose starting applications for Ubuntu 20.04.

Disk Partitioning

Next, you’ll be presented with an Installation Type dialog. You can wipe the hard drive clean prior to installing Ubuntu by clicking Erase disk and install Ubuntu. If you go this route, skip ahead to the next step.

Advanced users may want to edit Advanced Features. Use this to specify your own disk partitions or set other advanced options:

  • Use LVM with the new Ubuntu installation: LVM stands for Logical Volume Management. This is a tool for dynamically managing different virtual drives on your system. It’s much like an enhanced version of the gparted tool.
  • Encrypt the new Ubuntu installation for security: This will encrypt the drive’s contents. You’ll choose a security key, which will be required to decrypt and use the drive.
  • Experimental: Erase disk and use ZFS:  ZFS refers to Zettabyte File System, but it has grown into a hybrid file system and volume manager. Since it’s still being tested, avoid this setting on mission-critical production systems.

If you’d rather create your own hard drive partitions, click Something Else.

The next screen will allow you to create your own partition table and logical drives. This lets you divide a physical hard drive into different partitions. The operating system sees partitions as individual drives.

Note: Some users create their /home directory on a separate partition. If Ubuntu needs to be reinstalled, the partition with the /home directory is unaffected.

Click Continue to apply your changes to the drive partitions.

You’ll be asked to Write changes to disks?  None of the options you’ve selected are permanent until you click Continue on this screen.  Click Continue to proceed.

Select Time Zone

Once the system formats the disk partitions, the installer will ask Where are you?

Type the nearest large city into the box, and the system will set your local time zone.

Click Continue.

Create User Account

Next, you’ll need to configure a user account. Fill in the following fields:

  • Name: Your actual name.
  • Computer name: This is the hostname or network name.
  • Username: The user account name you want to use.
  • Password: Enter and confirm a strong password – the installer will automatically evaluate your password strength.
  • Log in automatically: This is not recommended for publicly accessible servers.
  • Require my password to log in: This is recommended for publicly accessible servers.

Click Continue to install Ubuntu.

Once the installer finishes, remove the Ubuntu installation media. You’ll be prompted to Restart Now.

Installation of 20.04 complete.

The system should boot into your fresh install of Ubuntu 20.04.


You should now have successfully installed Ubuntu 20.04 on your computer.

If you’re on a network, you may see a prompt to install updates. Install them, the only time to avoid updates is when newer versions conflict with mission-critical software.
