Editor’s note: Part Two of the Debian Guide is now online.
An Illustrated Debian 7 Installation Guide
First of all you need an installation image (ISO file) which you can download from www.debian.org. I recommend the small network install image. After downloading the file, copy it to a blank CD, DVD or USB memory-stick. For information on creating a bootable USB memory stick, see the article Create a Bootable Live USB Thumb Drive or Rescue Drive Using UNetbootin.
If you´re installing to a virtualbox you’re ready to continue to the next step. However, if you’re installing directly to your hard drive as a native installation, you should connect to the Internet using an Ethernet cable since not all Wi-Fi cards are supported. For example, I have an Intel Wi-Fi card for which there are no drivers included in the Debian installation media, so they need to be downloaded manually later.
If you already have another operating system installed you can keep it, but be sure you have enough room to add Debian and a Swap partition.
Ok, let’s get started with the installation! Just click on the first image below, the one with the caption “Beginning your Debian install,” and follow the slide show until the installation is complete. Beneath each image, I’ll guide you through the installation process.
