I want to sell my computer, how can I "preinstall" Ubuntu without configuring it? [duplicate]

Use the built-in OEM install functionality!

It's very easy to install Ubuntu on a computer for someone else, so that you can customize it for their needs but they can still perform the final basic setup (username, password, language, etc.).

Phase 1. Pre-installation

  1. Press any key to interrupt the LiveCD/LiveUSB autoboot; then press F4 and select OEM Install, and then "Install Ubuntu"

    enter image description here

  2. Enter a "company name" (it will only be used in error reports, etc.)

    enter image description here

  3. Continue installing...

  4. Enter a temporary username, password and machine-name for the customization phase

    enter image description here

  5. Restart

    enter image description here

Phase 2. Customization

  1. You are now in the customization phase:

    enter image description here

  2. Perform customization: Upgrades, updates, install software, remove software, change wallpapers, etc. In the sample below, we just use the terminal to change the Ubuntu update mirror to one closer to New York City.

  3. When you are done, close all windows and double-click on the Prepare for shipping to end-user icon on the desktop, which will show the message as below:

Phase 3. End-user configuration/"installation"

  1. When the receiver first boots up the computer, he/she will have to select a language:

    enter image description here

  2. ...and their location/time zone...

    enter image description here

  3. ...and keyboard layout...

    enter image description here

  4. They then choose their username, password, machine-name and whether to encrypt their home directory:

    enter image description here

  5. Ubuntu takes a few seconds to perform these final customizations...

    enter image description here

  6. ...and takes the user directly to their new login screen!

I originally thought this feature was only available in the alternate installer but I have been corrected. I was able to boot up a USB key for the desktop CD, holding down the left shift key until I was asked to choose a language, and then I hit F4 and was presented with this menu:

Colin Watson also notes that you can enable oem-config/enable=true as a boot parameter to expose the feature. After using it it prompted me with OEM-looking prompts:

If you are using the alternate installer you can just hit F4 and choose OEM Install right from the first screen:

When the boot menu comes up all you have to do is select "Install in OEM Mode" then walk through the rest of the process.

Here is a screenshot of this option from Ubuntu 12.04 installation. You need to press a key to bring this option menu just after starting to boot the Live CD or USB.
