Ticket: [[!tails_ticket 6560]]
[[!toc levels=2]]
# One possible plan
Goal: avoid the need to disable Secure Boot in the firmware
configuration. Tails should boot out-of-the-box with Secure Boot
enabled, without the user having to do _anything_ special about it.
Means: use the shim signed by Microsoft + GRUB2.
We don't support booting on a custom built kernel, so that should be
relatively easy.
Resources
=========
* Debian's [[!debwiki SecureBoot desc="Secure Boot support"]] will be
done for GRUB first, unclear if other bootloaders will be supported
- tracker bug: [[!debbug 820036]]
- shim is [[!debpts shim-signed desc="in Debian"]] (signed by the
Microsoft UEFI CA) but grub2-signed is not ([[!debbug 820050 desc="RFP bug"]]).

- [Ubuntu Privacy Remix](https://www.privacy-cd.org/)'s next release
(UPR 12.04r1) will support UEFI; a beta is available; they copied
the solution from Ubuntu 13.10 (beta): the shim bootloader and
a corresponding GRUB binary which passes secure boot. See their
[build script](https://www.privacy-cd.org/en/tutorials/build-your-own-cd/79).
