How to install Ubuntu: run Linux on your laptop or PC

Ubuntu has branded itself as the friendly face of Linux, and this focus on accessibility extends to the setup. The OS is remarkably easy to find, download and install, and during the past few versions, Canonical has done sterling work in streamlining the process and making it easier to handle.

How to install Ubuntu

Before you install, though, there are some decisions to be made. First of all, you need to know which version to install.

For simplicity’s sake, we’ll ignore derivatives such as Kubuntu and Xubuntu, not to mention server variants, and focus on the core Ubuntu Desktop and Ubuntu Netbook Editions.

32-bit or 64-bit?

The arguments over whether to go for 32- or 64-bit versions of Ubuntu mirror those over the 32- and 64-bit versions of Windows. 64-bit Ubuntu is marginally faster in tests and adds support for more than 4GB of RAM.

There are issues with hardware and software compatibility, although these are easing, and some applications either run more slowly in 64-bit mode or won’t run at all without some tweaking.

Confusingly, Canonical cites the 32-bit version as the recommended choice on the Desktop Edition download page but then goes in favor of the 64-bit version on a help page. In our experience, the advantages of the 64-bit version make sense, and problems are relatively few and far between.

Installation methods

The standard method of installing Ubuntu has generally been to download the ISO file and burn it to a CD, but Canonical is aware that netbook owners may not have access to a CD drive, and that a USB stick is often more convenient.

It’s also possible to try Ubuntu from USB or CD or even install it to a USB drive as a persistent installation to give you the same desktop and applications on any PC. For now, though, we’ll assume you want to install it to a hard disk.

The simplest way is with a full install, and if you have an old PC, laptop, or netbook gathering dust, this is a great way to make it genuinely useful once again.

It’s a clean and easy installation; the installer will happily wipe your old Windows partition, and Ubuntu’s generous system requirements mean it will run happily on a single-core CPU with 1GB of RAM. It’s even possible to run it on a 1GHz CPU with 256MB of RAM, although we recommend at least 512MB.

Ubuntu’s generous system requirements mean it will run happily on a single-core CPU with 1GB of RAM.

Run it on an Atom laptop – the standardized hardware is an easy target for Ubuntu’s installer – and it’s unlikely you’ll want to run Windows ever again.

You can also install Ubuntu alongside an existing Windows setup. Run the Ubuntu installer and it will give you all the options you need to set up Ubuntu and Windows partitions manually, or you can use the easy “Install Alongside” option, decide how much space to give each operating system and let Ubuntu handle the rest.

The two operating systems work smoothly without any interaction, and both Windows and Ubuntu will run at maximum speed.
