Now that Secure Boot is supported, what special instructions does one have to follow to install Ubuntu on a UEFI Secure Boot enabled PC shipped with Windows 8?
As I understand, Ubuntu >= 12.04.2 ships with signed GRUB2. I searched but cannot get past the "supported" statement. I am looking for specific instructions on registering Ubuntu keys to let the firmware boot Ubuntu.
UPDATE:
Thanks. SecureBoot in Ubuntu 12.10 gives me the answer. The Ubuntu first-stage EFI bootloader is signed by Microsoft. The last time I read, Ubuntu had plans to publish their own key which had to be registered in the firmware's database before installing. May be I did not track the story long enough to realize that it is not the case anymore.

Probably start here: help.ubuntu.com/community/UEFI
UEFI (~EFI) is a firmware interface that is widespread on recent computers, especially those more recent than 2010. It is intended to replace the traditional BIOS firmware interface that is prevalent on earlier machines. This page provides information about installing and booting Ubuntu using EFI, as well as about switching between EFI mode and legacy BIOS mode using Ubuntu.
UPDATE:
Ubuntu 12.10 is intended to be able to be used with Secure Boot.
