The world of operating systems is vast and varied, and one of the most popular choices among users is Ubuntu. With the release of Ubuntu 22.04, many users are wondering whether they can install it on their older machines. The answer largely depends on the type of firmware interface your machine uses: UEFI (Unified Extensible Firmware Interface) or BIOS (Basic Input Output System). In this article, we’ll delve into the differences between UEFI and BIOS, and discuss the process of installing Ubuntu 22.04 on older machines.
Yes, it is possible to install Ubuntu 22.04 on older machines that use BIOS. However, there have been reports of issues with non-UEFI machines, so it’s recommended to use utilities like
Rufus to create a bootable USB drive and verify the ISO file’s integrity.
Understanding UEFI and BIOS
Before we dive into the installation process, it’s important to understand the differences between UEFI and BIOS. BIOS is the old standard firmware interface that has been used in PCs since the 1980s. It’s a simple system that allows your computer to start up and load the operating system.
On the other hand, UEFI is the newer standard that offers several advantages over BIOS. It supports larger hard drives, faster boot times, more security features, and a graphical interface. However, it’s not always compatible with older machines, which primarily use BIOS.
Ubuntu 22.04 and Older Machines
Ubuntu 22.04 does not officially require UEFI and should be able to boot on BIOS machines. However, there have been reports of issues with non-UEFI, BIOS-only machines failing to boot Ubuntu 20.10 Groovy and later versions. This could be the reason why you are experiencing difficulties booting Ubuntu 22.04 on your old machines.
Creating a Bootable USB Drive
To create a bootable USB drive for these machines, you can try using the
mkusb utility from the
unstable PPA. Install
mkusb by adding the PPA and running the necessary commands:
sudo add-apt-repository ppa:mkusb/unstable sudo apt-get update sudo apt-get install mkusb
Once installed, you can use the
mkusb > dus option to prepare the flash drive. The
dus option stands for “Do USB Stuff”, which is a simple and user-friendly interface for creating bootable USB drives.
Another option is to use the
Rufus utility on a Windows machine. Download and run
Rufus as an administrator. Select the correct USB drive, choose the Ubuntu ISO, and set the partition scheme to MBR and the target system to BIOS or UEFI. Start the process and select the ISO image mode when prompted. Be aware that all data on the USB drive will be destroyed during this process.
Verifying the ISO File
It is also recommended to verify the integrity of the downloaded ISO by checking the checksums. This ensures that the ISO file is not corrupted. You can use tools like
sha256sum to check the checksum of the ISO file:
Compare the output with the official Ubuntu checksums, which can be found on the Ubuntu Hashes page.
In summary, Ubuntu 22.04 should be able to boot on BIOS machines, but there have been reports of issues with non-UEFI machines. You can try using
Rufus utilities to create a bootable USB drive. Verifying the ISO file’s integrity is also recommended. By following these steps, you should be able to successfully install Ubuntu 22.04 on your older machine.
