Is it possible to install Ubuntu 11.04 with full disk encryption?

Previously versions have had an alternate install cd with a text interface where you could enable encryption for your drives. This one is fully graphical and is missing that encryption option.

NOTE: the alternate CD is no longer available since Ubuntu 12.10. From this last release version you can encrypt the entire disk from the normals Live editions (LiveUSB, LiveCD, LiveDVD). – Lucio Feb 27 '13 at 23:18

  1. Go to and download the alternate install CD for your architecture.
  2. Burn the .iso to a blank CD.
  3. Reboot with the CD in the drive, and allow the computer to boot from the CD.
  4. On the Ubuntu alternate CD's menu, select "Install": Alternate CD's menu
  5. Follow the installer's instructions until you get to the step entitled "Partition Disks".
  6. Choose "Guided - use entire disk and set up encrypted LVM" from the menu. Partition disks menu
  7. Finish the installation by following the instructions on the screen.

What encryption mechanism (i.e. dm-crypt) does this use? – Felix Mar 21 '12 at 11:33
It uses dm-crypt for encryption, complying with the LUKS specification, I believe. – Flimm Mar 26 '12 at 11:38
