7 If you want to help Tails, UEFI support is ready for testing!
9 Even if you don't have access to UEFI hardware, and Tails already
10 works fine for you, it is useful that you make sure that these changes
11 do not break anything you care about.
13 UEFI support allows you to start Tails using a USB stick on recent
14 hardware, and especially on Mac. It enables you to use great
15 features such as [[doc/first_steps/persistence]] and [[automatic
16 upgrades|doc/first_steps/upgrade]].
18 Please see if it works for you:
20 * If you have previously had problems starting Tails on your
21 hardware, using a USB stick created with <span
22 class="application">Tails Installer</span>: a new Tails with UEFI
23 support may fix these problems.
25 * If you are used to starting Tails using a USB stick created with <span
26 class="application">Tails Installer</span>: make sure that UEFI support
27 does not break things for you.
31 # How to try UEFI support?
33 These instructions allow you to try an **experimental version of
34 Tails** with UEFI support. Use it only for testing.
36 To follow these instructions, you will need two boot devices
37 compatible with Tails: either a DVD and a USB stick, or two
40 Follow these steps exactly. Do not try to upgrade an existing Tails
43 1. Download the latest [test ISO](http://nightly.tails.boum.org/build_Tails_ISO_devel/).
45 1. Use any officially supported way to
46 [[install|doc/first_steps/installation]] the experimental ISO image
47 to first device, that we will call *Alpha*, that can be a DVD or a USB stick. At this point,
48 device *Alpha* does not support UEFI.
50 1. Start Tails from device *Alpha*, on a computer that starts fine
51 with the latest official version of Tails.
53 1. Take detailed notes about how this boot goes.
55 1. *Clone & Install* device *Alpha* onto another USB stick [[with <span
56 class="application">Tails
57 Installer</span>|doc/first_steps/installation]]. We
58 will call this second device *Beta*, and it supports UEFI.
60 1. Get the computer you are really interested in using with Tails.
61 It may start fine with the latest official version of Tails,
64 1. Make sure this computer is configured to start with legacy BIOS and
65 not only UEFI. Try any of the following options if available:
72 1. Start Tails from the USB stick *Beta* on this computer.
74 1. Take detailed notes about how this boot goes. If it fails, proceed
77 1. Start Tails from the USB stick *Beta* in UEFI mode, again on the
79 * On a Mac: plug the USB stick, press the power button, immediately
80 press the Alt key until a boot menu appears, and then choose
81 the entry that reads *Boot EFI* and looks like a USB stick.
82 * On a PC: look first into the boot menu; if nothing reads *EFI* in
83 there, look in the BIOS settings, and try any of the following
84 options if available: `Disable Legacy mode`, `Disable CSM boot`,
87 1. Take detailed notes about how this boot goes.
89 1. Report your results to us, as documented below.
91 Reporting success and failure
92 =============================
94 We are interested both in your success and failure reports. The exact
95 information we need in a report depends on whether you are reporting
100 From Tails started in UEFI mode, please [[send us
101 a report|doc/first_steps/bug_reporting]] with <span
102 class="application">WhisperBack</span>. Include your testing notes,
103 and the answer to the following questions:
105 1. What is the number of the step you are reporting about?
106 1. What is the filename of the ISO you have been testing?
107 1. How exactly did you prepare the boot device?
108 1. What exact steps did you follow to start Tails from this device?
112 If you find a computer that cannot start with an experimental version
113 of Tails that supports UEFI, please first check if the problem you are
114 experiencing is [[already known|test_UEFI#known_issues]]. If it is,
115 then you do not need to send us a report. If not, read on.
117 Include the answer to the following questions:
119 1. What is the number of the step you are reporting about?
120 1. What is the filename of the ISO you have been testing?
121 1. How exactly did you prepare this boot device?
122 1. What exact steps did you follow to start Tails from this device?
123 1. What is the brand and model of the computer your have been
125 1. What is the type, brand, and model of this boot device?
126 1. What exactly happens when you tried to start Tails from
129 Please also consider trying to reproduce the problem with the latest
130 official version of Tails, installed in the same way, on the same
131 hardware. Include the results in your report.
