If you want to help Tails, UEFI support is ready for testing!

Even if you don't have access to UEFI hardware, and Tails already works fine for you, it is useful that you make sure that these changes do not break anything you care about.

UEFI support allows you to start Tails using a USB stick on recent hardware, and especially on Mac. It enables you to use great features such as [persistence](https://tails.boum.org/news/../doc/first_steps/persistence/index.en.html) and [automatic upgrades](https://tails.boum.org/news/../doc/first_steps/upgrade/index.en.html).

Please see if it works for you:

* If you have previously had problems starting Tails on your hardware, using a USB stick created with Tails Installer: a new Tails with UEFI support may fix these problems.

* If you are used to starting Tails using a USB stick created with Tails Installer: make sure that UEFI support does not break things for you.

# How to try UEFI support?

These instructions allow you to try an **experimental version of Tails** with UEFI support. Use it only for testing.

To follow these instructions, you will need two boot devices compatible with Tails: either a DVD and a USB stick, or two USB sticks.

Follow these steps exactly. Do not try to upgrade an existing Tails USB stick.

1. Download the latest [test ISO](http://nightly.tails.boum.org/build_Tails_ISO_feature-uefi/).

2. Use any officially supported way to [install](https://tails.boum.org/news/../doc/first_steps/installation/index.en.html) the experimental ISO image to first device, that we will call _Alpha_, that can be a DVD or a USB stick. At this point, device _Alpha_ does not support UEFI.

3. Start Tails from device _Alpha_, on a computer that starts fine with the latest official version of Tails.

4. Take detailed notes about how this boot goes.

5. _Clone & Install_ device _Alpha_ onto another USB stick [with Tails Installer](https://tails.boum.org/news/../doc/first_steps/installation/index.en.html). We will call this second device _Beta_, and it supports UEFI.

6. Get the computer you are really interested in using with Tails. It may start fine with the latest official version of Tails, or not.

7. Make sure this computer is configured to start with legacy BIOS and not only UEFI. Try any of the following options if available:

    * Enable Legacy mode
    * Disable Secure boot
    * Enable CSM boot
    * Disable UEFI
  8. Start Tails from the USB stick _Beta_ on this computer.


9. Take detailed notes about how this boot goes. If it fails, proceed to the next test:

10. Start Tails from the USB stick _Beta_ in UEFI mode, again on the same computer:

    * On a Mac: plug the USB stick, press the power button, immediately press the Alt key until a boot menu appears, and then choose the entry that reads _Boot EFI_ and looks like a USB stick.
    * On a PC: look first into the boot menu; if nothing reads _EFI_ in there, look in the BIOS settings, and try any of the following options if available: `Disable Legacy mode`, `Disable CSM boot`, and `Enable UEFI`.
  11. Take detailed notes about how this boot goes.


12. Report your results to us, as documented below.

# Reporting success and failure

We are interested both in your success and failure reports. The exact information we need in a report depends on whether you are reporting success or failure.

## Reporting success

>From Tails started in UEFI mode, please [send us a report](https://tails.boum.org/news/../doc/first_steps/bug_reporting/index.en.html) with WhisperBack. Include your testing notes, and the answer to the following questions:


1. What is the number of the step you are reporting about?
2. What is the filename of the ISO you have been testing?
3. How exactly did you prepare the boot device?
4. What exact steps did you follow to start Tails from this device?

## Reporting failure

If you find a computer that cannot start with an experimental version of Tails that supports UEFI, please first check if the problem you are experiencing is [already known](https://tails.boum.org/news/./test_UEFI/index.en.html#known_issues). If it is, then you do not need to send us a report. If not, read on.

Include the answer to the following questions:

1. What is the number of the step you are reporting about?
2. What is the filename of the ISO you have been testing?
3. How exactly did you prepare this boot device?
4. What exact steps did you follow to start Tails from this device?
5. What is the brand and model of the computer your have been testing on?
6. What is the type, brand, and model of this boot device?
7. What exactly happens when you tried to start Tails from this device?

Please also consider trying what follows, and including the results in your report:

1. Try to reproduce the problem with the latest official version of Tails, installed in the same way, on the same hardware.
2. Try to reproduce the problem with an [experimental ISO built from the devel branch](http://nightly.tails.boum.org/build_Tails_ISO_devel/), installed in the same way, on the same hardware.

In any case, please email your report to [intrigeri@???](mailto:intrigeri@boum.org). You may encrypt it with OpenPGP to:
