8 If you want to help Tails, UEFI support is ready for testing!
10 Even if you don't have access to UEFI hardware, and Tails already
11 works fine for you, it is useful that you make sure that these changes
12 do not break anything you care about.
14 UEFI support allows you to start Tails using a USB stick on recent
15 hardware, and especially on Mac. It enables you to use great
16 features such as [[doc/first_steps/persistence]] and [[automatic
17 upgrades|doc/upgrade]].
19 Please see if it works for you:
21 * If you have previously had problems starting Tails on your
22 hardware, using a USB stick created with <span
23 class="application">Tails Installer</span>: a new Tails with UEFI
24 support may fix these problems.
26 * If you are used to starting Tails using a USB stick created with <span
27 class="application">Tails Installer</span>: make sure that UEFI support
28 does not break things for you.
32 # How to try UEFI support?
34 These instructions allow you to try an **experimental version of
35 Tails** with UEFI support. Use it only for testing.
37 To follow these instructions, you will need two boot devices
38 compatible with Tails: either a DVD and a USB stick, or two
41 Follow these steps exactly. Do not try to upgrade an existing Tails
44 1. Download the latest [test ISO](http://nightly.tails.boum.org/build_Tails_ISO_devel/).
46 1. Use any officially supported way to
47 install the experimental ISO image
48 to first device, that we will call *Alpha*, that can be a DVD or a USB stick. At this point,
49 device *Alpha* does not support UEFI.
51 1. Start Tails from device *Alpha*, on a computer that starts fine
52 with the latest official version of Tails.
54 1. Take detailed notes about how this boot goes.
56 1. *Clone & Install* device *Alpha* onto another USB stick with <span
57 class="application">Tails
59 will call this second device *Beta*, and it supports UEFI.
61 1. Get the computer you are really interested in using with Tails.
62 It may start fine with the latest official version of Tails,
65 1. Make sure this computer is configured to start with legacy BIOS and
66 not only UEFI. Try any of the following options if available:
73 1. Start Tails from the USB stick *Beta* on this computer.
75 1. Take detailed notes about how this boot goes. If it fails, proceed
78 1. Start Tails from the USB stick *Beta* in UEFI mode, again on the
80 * On a Mac: plug the USB stick, press the power button, immediately
81 press the Alt key until a boot menu appears, and then choose
82 the entry that reads *Boot EFI* and looks like a USB stick.
83 * On a PC: look first into the boot menu; if nothing reads *EFI* in
84 there, look in the BIOS settings, and try any of the following
85 options if available: `Disable Legacy mode`, `Disable CSM boot`,
88 1. Take detailed notes about how this boot goes.
90 1. Report your results to us, as documented below.
92 Reporting success and failure
93 =============================
95 We are interested both in your success and failure reports. The exact
96 information we need in a report depends on whether you are reporting
101 From Tails started in UEFI mode, please [[send us
102 a report|doc/first_steps/bug_reporting]] with <span
103 class="application">WhisperBack</span>. Include your testing notes,
104 and the answer to the following questions:
106 1. What is the number of the step you are reporting about?
107 1. What is the filename of the ISO you have been testing?
108 1. How exactly did you prepare the boot device?
109 1. What exact steps did you follow to start Tails from this device?
113 If you find a computer that cannot start with an experimental version
114 of Tails that supports UEFI, please first check if the problem you are
115 experiencing is [[already known|test_UEFI#known_issues]]. If it is,
116 then you do not need to send us a report. If not, read on.
118 Include the answer to the following questions:

131 official version of Tails, installed in the same way, on the same
132 hardware. Include the results in your report.
