I would like to pre-install Ubuntu on a computer for someone. I may want to customize it for them, but in the end they need to be able to choose a username, password, etc. when they first boot it up. (Also called an OEM install).
How do I do this?
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
If you are using the alternate installer you can just hit F4 and choose OEM Install right from the first screen:
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
Phase 2. Customization
Phase 3. End-user configuration/"installation"
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 more detailed instructions with screen shots:
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.
