Installing Debian 11 GNU/Linux
Debian can be downloaded from the following link: Download Debian 11
Once you have downloaded your chosen "iso" image of Debian, you will need to burn this image to a DVD. For software that can do this, you can search for "dvd iso burning software" in the search box provided above. Your computer may already have CD/DVD burning software already installed such as "Brasero, K3B, Nero, CDBurnerXP or Roxio". Once you have burned your chosen "iso" image of Debian to your Media, you will need to place your DVD disc into the DVD drive of the target system and reboot your system. As your computer system reboots, you will need to press the appropriate key to access your system's BIOS settings. On many systems this key will be "F8", "F11" or "F12". Most systems will display a message indicating which key needs to be pressed. Once you have access to your system's BIOS settings, you will need to modify the boot order of your system to boot from CD/DVD first. Once this change has been made, you can now reboot your system and follow the installation guide below. If you are installing into a Virtual Environment, simply copy the downloaded "iso" image to the relevant location provided by your software.
