I recommend you put a SSD into that laptop 🙂 before continuing.

What you do is: You get another computer / laptop capable of burning DVDs:

http://cdimage.debian.org/debian-cd/8.3.0/amd64/iso-cd/debian-8.3.0-amd64-netinst.iso (brasero did that nicely on a DVD-R, the dell would not take accept CD-R „selecting boot device failed“)

Hit F12 during boot and select your DVD-Drive.

You should see all the normal „Language – Region“ stuff.

Then the Wifi missing firmware iwlwifi-6000-4.ucode popup comes:

debian 8.3.0 loading missing non free firmware for wifi - dialog

What you do is you download this *.deb

http://ftp.de.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-iwlwifi_20160110-1_all.deb

mirror: firmware-iwlwifi_20160110-1_all.deb.gz

and place it on a FAT32-USB Stick.

Attach it to your laptop, wair 3 seconds, hit enter … and it should continue without error.

debian 8.3.0 loading missing non free firmware for wifi success

PS: I Stick to ext3 for the next 5 years until ext4 is stable.

alternatively:

use unofficial non-free iso – that allready has the drivers on it. (Richard Stallman IS VERY MUCH AGAINST ANYTHING THAT IS NON-FREE) For good reasons of privacy… because after all a backdoor in your network card firmware could really compromise your system in terms of security and privacy.

Unofficial non-free images including firmware packages:

recommendation: ALWAYS GO FOR THE MINIMAL and load packages during setup straight from the internet…

Here are some extra images, equivalent to the normal images we produce regularly except in that they also include non-free firmware to make things easier on some systems requiring proprietary but redistributable firmware. See http://wiki.debian.org/Firmware for more details.

There are two types of image here:

  • „netinst“ install CDs that also include firmware to make installation easier
  • live images including firmware packages pre-installed

The current and current-live directories contain images that match up with the latest stable Debian release.
