How To Create an EFI System Partition for Ubuntu 18.10 Installation

Ubuntu 3

If you’re planning to install Ubuntu 18.10 on a computer system, it’s crucial to understand how to create an EFI System Partition (ESP). This partition is necessary for computers that use the Unified Extensible Firmware Interface (UEFI) as a replacement to BIOS. In this guide, we will walk you through the steps to create an ESP for Ubuntu 18.10 installation.

Quick Answer

To create an EFI System Partition (ESP) for Ubuntu 18.10 installation, you need to boot your system in UEFI mode and manually partition your hard drive during the installation process. Allocate around 200-500MB of space for the ESP. After installation, you can verify the creation of the ESP by running the command "sudo fdisk -l" in the terminal.

What is an EFI System Partition?

The EFI System Partition (ESP) is a partition on a data storage device that is used by computers adhering to the UEFI. When a computer is booted, UEFI firmware loads files stored on the ESP to start installed operating systems and various utilities.

Preparing for Installation

Before you begin, ensure that your system is set to boot in UEFI mode. If you’re using a virtual machine, such as VMWare, you may need to adjust the settings to enable UEFI booting. If you’re booting from a Live USB or DVD, ensure that it’s configured to boot in UEFI mode.

Creating an EFI System Partition

Once you’ve booted in UEFI mode, follow these steps:

  1. Launch the Ubuntu Installer: Start the installation process as you normally would until you reach the “Installation type” screen.
  2. Choose ‘Something else’: On the “Installation type” screen, select the ‘Something else’ option to manually partition your hard drive and then click ‘Continue’.
  3. Create a new partition: In the next screen, you’ll see a list of your current partitions. To create a new partition, select the free space and click on the ‘+’ button.
  4. Configure the new partition: A new window will pop up for you to configure the new partition. In the ‘Use as:’ dropdown, select ‘EFI System Partition’. You should allocate around 200-500MB of space for this partition. After you’ve made your selection, click ‘OK’.
  5. Complete the installation: Once you’ve created the EFI System Partition, you can continue with the rest of the installation as normal.

Verifying the Installation

After the installation is complete, you can verify that the ESP has been created correctly. To do this, open a terminal and run the following command:

sudo fdisk -l

This command lists all the partitions on your system. Look for a partition with the ‘EFI System’ under the ‘Type’ column. This is your ESP.

Conclusion

Creating an EFI System Partition is a crucial step when installing Ubuntu 18.10 on a system that uses UEFI. By following this guide, you should be able to successfully create an ESP and install Ubuntu 18.10. If you encounter any issues during the installation process, don’t hesitate to seek help from the Ubuntu community or refer to the official Ubuntu documentation.

Remember, always ensure that you have a backup of your data before making any changes to your system’s partitions.

What is the difference between BIOS and UEFI?

BIOS (Basic Input/Output System) is the traditional firmware interface used by older computer systems, while UEFI (Unified Extensible Firmware Interface) is the modern replacement for BIOS. UEFI offers more advanced features, such as faster boot times, larger hard drive support, and improved security.

Why is an EFI System Partition necessary for Ubuntu 18.10 installation?

The EFI System Partition (ESP) is necessary for computers that use UEFI as it stores the necessary files to boot the installed operating systems. Without an ESP, the system would not be able to start Ubuntu 18.10 or any other operating system installed on the computer.

How much space should I allocate for the EFI System Partition?

It is recommended to allocate around 200-500MB of space for the EFI System Partition. This size is sufficient for storing the necessary boot files and allows for future updates and additions to the partition.

Can I create the EFI System Partition during the Ubuntu installation process?

Yes, you can create the EFI System Partition during the Ubuntu installation process by selecting the ‘Something else’ option for manual partitioning. Follow the steps mentioned in the guide to create the EFI System Partition.

How can I verify if the EFI System Partition has been created correctly?

After the installation is complete, you can open a terminal and run the command ‘sudo fdisk -l’. This command will list all the partitions on your system. Look for a partition with the ‘EFI System’ label under the ‘Type’ column to verify that the EFI System Partition has been created correctly.

What should I do if I encounter any issues during the installation process?

If you encounter any issues during the installation process, it is recommended to seek help from the Ubuntu community or refer to the official Ubuntu documentation. They can provide guidance and solutions to any problems you may encounter.

Should I backup my data before creating an EFI System Partition?

Yes, it is always important to have a backup of your data before making any changes to your system’s partitions. While creating an EFI System Partition is a relatively safe process, unexpected issues can occur, and having a backup ensures that your data is protected.
