Can I Install Ubuntu on This PC? Requirements and ISO Choice

Can I install Ubuntu on a 12-year-old PC?

Usually yes if it is a 64-bit Intel or AMD PC with at least 6 GB of RAM and 25 GB of free storage. For example, an older desktop with an Intel Core i7-class processor, 8 GB of RAM, an x64 processor, and ample disk space clears Canonical's published CPU, memory, and storage baseline on paper. Download the amd64 image. Treat graphics, Wi-Fi, suspend, storage-controller mode, and real-world speed as separate checks.

If the older PC has a legacy NVIDIA card, do not assume that the card is supported just because the CPU and RAM qualify. Use Try Ubuntu from USB and test the display and the workloads you care about before installing.

Ubuntu Desktop 26.04 system requirements

Canonical's current Ubuntu Desktop page gives this baseline:

These are starting requirements, not a performance guarantee. A modern browser, 3D application, legacy GPU, unusual Wi-Fi device, or firmware setting can still make an older computer slow or incompatible.

Which Ubuntu ISO should I download?

Ubuntu's current Desktop download page presents two relevant architecture choices:

• Intel or AMD 64-bit: for 64-bit Intel and AMD desktop processors. The amd64 label is an architecture name, not an AMD-only restriction. Intel x64 processors use this image too.
• ARM 64-bit: for computers with an ARM processor. Do not choose it for an ordinary Intel or AMD PC because the label sounds newer.

Canonical's current Ubuntu Desktop page does not present a normal x86 32-bit Desktop image. A 32-bit-only computer therefore needs a different, specifically verified operating-system path; it is not a normal match for the current Ubuntu Desktop download.

How do I check x64 or ARM64 before downloading?

If the PC is still running Windows, open Settings > System > About and read System type. A result such as 64-bit operating system, x64-based processor points to Ubuntu's Intel or AMD 64-bit image. An ARM-based processor points to ARM64. The installed Windows version is not the deciding factor; the processor architecture is.

If Linux is already installed, uname -m commonly reports x86_64 for the Intel/AMD 64-bit family and aarch64 for ARM64. When the result is unclear, identify the exact CPU model from the machine's firmware or manufacturer documentation before writing an installer.

How can I test Ubuntu hardware without installing?

Canonical recommends checking the Ubuntu certified hardware list when the exact device is available. If it is not listed, create a bootable USB and select Try Ubuntu instead of immediately installing. Test the display, keyboard, touchpad, Ethernet or Wi-Fi, audio, suspend, storage access, and the workload that matters to you before changing the internal disk.

For NVIDIA hardware, do not infer support from the GPU name alone. Ubuntu's installer can offer third-party drivers when network access is available, and Canonical documents the ubuntu-drivers tool for checking which driver branches are available for the detected hardware. If no suitable driver is offered, treat that as an unresolved compatibility issue rather than promising that the installation will be trouble-free.

How do I install Ubuntu from the official source?

1. Open Canonical's Download Ubuntu Desktop page and choose the image matching the CPU architecture.
2. Create a bootable USB with an image-writing tool. Copying the ISO file onto a USB drive as an ordinary file is not the same as writing installation media.
3. Back up files on both the target PC and the USB drive. Writing the image and installing Ubuntu can erase data.
4. Boot the target PC from the USB. On many PCs, F12, Escape, F2, or F10 opens the boot menu; the manufacturer determines the exact key.
5. Select Try Ubuntu first, test the hardware, and only then start the installer if the result is acceptable.

Canonical's installation tutorial also calls out device-specific issues such as Intel RST storage mode. Resolve those against Canonical's instructions before repartitioning a Windows installation.

What this answer can and cannot prove

A CPU architecture match answers which ISO to download. The published memory and storage requirements answer whether the machine clears Ubuntu's documented starting point. Neither one guarantees a good experience with modern browsers, 3D applications, proprietary peripherals, sleep and wake, or legacy NVIDIA hardware. A live USB test is the most useful next step when the exact model is not certified.

This guide does not promise that an old PC will feel fast, that every Windows application will run under Ubuntu, or that an ARM translation layer will make an x86 application compatible. Those are separate product, driver, or workload questions.

Use What-Version for the next architecture decision

If you are checking a Windows machine before downloading Ubuntu, the Windows ARM64 vs x64 vs x86 guide explains the labels you may see in System type. Use the Windows bitness guide for a slower walkthrough, and the official-source verification guide when a download page or mirror shows conflicting version information.
