+
+## Tails fails to start a second time on some computers ([[!tails_ticket 16389]])
+
+On some computers, after installing Tails to a USB stick,
+Tails starts a first time but fails to start a second time. In some
+cases, only BIOS (Legacy) was affected and the USB stick was not listed
+in the Boot Menu.
+
+We partially fix this issue in 3.14.1 but are still investigating it, so if it happens to you, please
+report your findings by email to <tails-testers@boum.org>. Mention the
+model of the computer and the USB stick. This mailing
+list is [archived publicly](https://lists.autistici.org/list/tails-testers.html).
+
+To fix this issue:
+
+1. Reinstall your USB stick using the same installation method.
+
+1. Start Tails for the first time and [[set up an administration
+   password|doc/first_steps/startup_options/administration_password]].
+
+1. Choose <span class="menuchoice">
+   <span class="guimenu">Applications</span>&nbsp;▸
+   <span class="guisubmenu">System Tools</span>&nbsp;▸
+   <span class="guimenuitem">Root Terminal</span>
+   </span> to open a <span class="application">Root Terminal</span>.
+
+1. Execute the following command:
+
+   <p class="pre command">sgdisk --recompute-chs /dev/bilibop</p>
+
+You can also test an experimental image:
+
+1. [Download the *.img* file from our development
+   server](https://nightly.tails.boum.org/build_Tails_ISO_bugfix-16389-recompute-chs/lastSuccessful/archive/build-artifacts/).
+
+1. Install it using the same installation methods.
+
+   We don't provide any OpenPGP signature or other verification technique
+   for this test image. Please only use it for testing.
+
+See the list of [[long-standing issues|support/known_issues]].
