Installing Debian 8.1

To install Debian 8.1 (jessie), download any of the following images (all i386 and amd64 CD/DVD images can be used on USB sticks too):

netinst CD image (generally 150-280 MB)

Blu-ray (via jigdo)

other images (netboot, flexible usb stick, etc.)

If any of the hardware in your system requires non-free firmware to be loaded with the device driver, you can use one of the tarballs of common firmware packages or download an unofficial image including these non-free firmwares. Instructions how to use the tarballs and general information about loading firmware during an installation can be found in the Installation Guide (see Documentation below).

netinst (generally 240-290 MB) non-free CD images with firmware

If you read only one document before installing, read our Installation Howto, a quick walkthrough of the installation process. Other useful documentation includes:

Errata

This is a list of known problems in the installer shipped with Debian 8.1. If you have experienced a problem installing Debian and do not see your problem listed here, please send us an installation report describing the problem or check the wiki for other known problems.

Errata for release 8.0

Desktop installations may not work using CD#1 alone
Due to space constraints on the first CD, not all of the expected GNOME desktop packages fit on CD#1. For a successful installation, use extra package sources (e.g. a second CD or a network mirror) or use a DVD instead.
Status: It is unlikely more efforts can be made to fit more packages on CD#1.
Powerpc boot messages are out of date
Bug #783569: powerpc CDs still talk about using the kernel command line to select a desktop, which is now obsolete - use the tasksel menu instead.
Status: A fix is already committed for this issue and it will be fixed in 8.1
Problems installing more than one desktop task at once
Bug #783571: It's not possible to install both GNOME and Xfce at the same time. There is a conflict in dependencies that causes package installations to fail.
Status: A fix is already proposed for this issue and it will hopefully be fixed in 8.1

Improved versions of the installation system are being developed for the next Debian release, and can also be used to install jessie. For details, see the Debian-Installer project page.
