Installing Linux by Adding a Dedicated Partition Alongside Windows, or Completely Re-Partitioning a Hard Drive to Replace Windows:
Below is a basic step-by-step guide for installing a Linux distro to your computer using a live CD/DVD/USB drive, which involves re-partitioning your hard drive:
- Go to the website for your Linux distro of choice and download an ISO image file to your computer.
- Burn the downloaded ISO image to a blank CD-R/DVD-R disk to create a live CD/DVD, or create a bootable USB drive. Click here to see an excellent guide from Ubuntu on how to do burn a live CD/DVD . Click here to see a guide for creating a bootable USB drive with Ubuntu . If you are not able to download the ISO image and burn it to a live CD/DVD or create a bootable USB drive, you can purchase a CD/DVD or preloaded USB drive from the Canonical Shop.
- If you plan to install Linux side-by-side with Windows by creating a dedicated partition, it is recommended that you completely defragment your hard drive before proceeding with the next step. If you plan to wipe your hard drive clean by re-formatting it and installing Linux in the place of Windows, you can skip this step.
- Insert the live CD/DVD or bootable USB drive into the computer which you want to run/install Linux.
- FOR OLDER COMPUTERS WITH BIOS: Restart your computer and it should run from the live CD/DVD or bootable USB drive as long as the CD/DVD drive or USB drive appears before the computer’s hard drive in the boot sequence in the computer’s BIOS. If the CD/DVD/USB drive is not first in the boot sequence, you will need to enter the BIOS settings and make the necessary changes.

FOR NEWER COMPUTERS WITH UEFI: If you have a newer computer with Windows 8 / UEFI, then you can click here to learn how to install Ubuntu.
- Follow the instructions from the live CD/DVD and enjoy!
- OPTIONAL: If you decide to completely replace Windows with Linux on your computer, there are a number of ways that you can re-format and re-partition your hard drive. With many Linux distros, such as Ubuntu, Kubuntu, Xubuntu, Lubuntu, and Linux Mint, you can have your hard drive re-formatted and re-partitioned automatically by choosing guided partitioning while installing. With this option, the Linux system files/folders and the “/home” folder are placed within the same partition, which is fine. However, once you become adept at manually working with partitions, it is preferable to install your root Linux system files/folders in a separate partition from your /home folder as shown in the picture below. One reason for this is if you need to re-install your Linux system, you can avoid re-copying all of your personal documents, pictures, videos, etc. in the /home folder which can remain intact in a system re-install. If you choose this configuration, you should dedicate a minimum of 10 GB to your Linux system “/” (root) partition. In the picture below, the / (root) partition is sda1 and the /home partition is sda2. The sda3 partition is reserved for the linuxswap, which is an overflow for RAM if needed; having a swap partition is more necessary on older hardware with limited RAM.

Installing Linux on a pre-Intel Mac PowerPC – Definitely for More Advanced Users:
Macs manufactured since 2006 use Intel chips and can run the same versions of Linux as typical Windows PCs. However, pre-Intel macs such as the PowerPC have processors with a different architecture, which requires different versions of Linux. Not all distros have these PowerPC-compatible versions, but fortunately some do have them. When installing from a live CD, just remember that in order to get a Mac to boot from the CD/DVD drive, you must hold down the “C” key while starting the computer.
