<p>Haiku's Boot Loader can help when you experience hardware related problems or want to choose which Haiku installation to start, if you have more than one (maybe on an installation CD or USB stick).<br/>
It's also handy after you installed a software component that acts up and prevents you from booting the system to remove it again. The <i>Disable user add-ons</i> option that's mentioned below, will start Haiku without loading user installed components, e.g. a driver.</p>
<p>To enter the Boot Loader options, you have to press and keep holding the <spanclass="key">SHIFT</span> key before the beginning of Haiku's boot process. If there's a boot manager installed, you can start holding <spanclass="key">SHIFT</span> before invoking the boot entry for Haiku. If Haiku is the only operating system on the machine, you can begin holding the key while still seeing boot messages from the BIOS.</p>

</td><td></td><td>There are several options to try in case of hardware related trouble. When moving the selection bar to an option, a short explanation appears at the bottom of the screen.
</td><td></td><td>Here you'll find several options that help with debugging or getting details for a bug report. Again, a short explanation for each option is displayed at the bottom.
<p><i>- Enable serial debug output</i><br/>

<i>- Enable debug syslog</i>

<p>If "debug syslog" is enabled, a warm reboot after a crash shows these additional options:</p>
<p><i>- Display syslog from previous session</i><br/>
<tr><tdclass="onelinetop"><b>Select fail safe video mode</b></td><td></td><td>If you had to activate the option <i>Use fail-safe video mode</i>, you can set resolution and color depth.</td></tr>

<p>After activating one or more options, you return to the main menu and continue booting, which presents you with this boot screen:</p>
