+<p>For the most part, rEFInd is easy to use; just use your keyboard's arrow keys to select the OS you want to boot or the utility you want to launch and press the Enter key. A few details aren't entirely intuitive, though, so this page describes them.</p>

<h2>Using Basic rEFInd Features</h2>
+</a>
<p>With rEFInd in place and added to your firmware's list of boot utilities, you can reboot your computer. Depending on your configuration, rEFInd may come up immediately or you may need to select it from your firmware's boot options or reconfigure your firmware to present rEFInd automatically. Unfortunately, I can't offer much specific advice on this score, since EFI implementations differ so much in their user interfaces.</p>
<p>Assuming rEFInd starts up correctly, you should see its main screen, which resembles the following:</p>
- <br /><center><img src="refind.png" align="center" width="905"
- height="389" alt="rEFInd presents a GUI menu for selecting your boot
+ <br /><center><img src="refind.png" align="center" width="734"
+ height="552" alt="rEFInd presents a GUI menu for selecting your boot
OS." border=2 /></center> <br />
-<p>If you don't press any key before the timeout (shown on the last line) expires, the default boot loader will launch. This is normally the first item in the menu, but you can adjust the default by editing the configuration file. (In this example, it's the SUSE loader, which is further identified by text above the timeout as <i>Linux 3.3.0-rc7 from ESP.</i>)</p>
+<p>If you don't press any key before the timeout (shown below the icons and description line) expires, the default boot loader will launch. This is normally the first item in the menu, but you can adjust the default by editing the configuration file. (In this example, it's the Ubuntu Linux loader, which is further identified by text above the timeout as <i>vmlinuz-3.5.0-27-generic from UBUNTU BOOT</i>.)</p>
-<p>This display is dominated by the central set of OS <i>tags</i> (icons), which in this example includes tags for OS X, Windows, Ubuntu, a generic Linux installation (ELILO, in fact), SUSE, and an unkown boot loader. All but the last of these are on hard disks, but the unknown boot loader is on an optical disc, as revealed by the small icons (known as <i>badges</i>) in the lower-right corner of the OS icons.</p>

-<p>In this example, the SUSE tag is selected. You can move the selection left by pressing the left arrow key and right by pressing the right arrow key. If your system has many boot loaders, an arrow icon will appear to the right of the boot loader list, indicating that the boot loader list will scroll when you move off the right edge. If you do this, an arrow icon will appear to the left of the icon list, indicating that you can scroll back in a similar manner. You can scroll the list by one line full of icons by using the Page Up or Page Down keys to move left and right, respectively. Moving past the final selection or using the down arrow key moves the selection to the second row of small tags, which launch ancillary programs or perform special actions. If you've moved the selection cursor to the second row, pressing the up arrow key or scrolling past the left edge of the second row moves the cursor to the top row. In this figure, these five tags are present:</p>
+<p>In this example, the Ubuntu tag is selected. You can move the selection left by pressing the left arrow key and right by pressing the right arrow key. If your system has many boot loaders, an arrow icon will appear to the right and/or left of the boot loader list, indicating that the boot loader list will scroll when you move off the edge. (Such arrows are visible to the right and left in the sample screen.) You can scroll the list by one line full of icons by using the Page Up or Page Down keys to move left and right, respectively. Moving past the final selection or using the down arrow key moves the selection to the second row of small tags, which launch ancillary programs or perform special actions. If you've moved the selection cursor to the second row, pressing the up arrow key or scrolling past the left edge of the second row moves the cursor to the top row. In this figure, these five tags are present:</p>
<ul>
<li>Launch the EFI shell</li>
-<p class="sidebar">As noted on the <a href="installing.html">Installing rEFInd</a> page, the <tt>gptsync</tt> utility is dangerous, but it's useful on some Mac systems that dual-boot with Windows. If you're using a UEFI-based PC, it's best to <i>not</i> install this utility!</p>
-
-<li>Launch the <tt>gptsync</tt> utility</li>
+<li>Launch the tool to create a hybrid MBR (<tt>gptsync</tt>)
<li>Produce an information page</li>
-<li>Shut down the computer</li>
-
<li>Reboot the computer</li>
+<li>Exit from rEFInd</li>
+
</ul>
-<p>The last three of these options are always available by default, but the first depends on the presence of the EFI shell program file, as described earlier. To get the <tt>gptsync</tt> icon, you must install <tt>gptsync.efi</tt> and adjust the <tt>showtools</tt> option in <tt>refind.conf</tt>, as well.</p>
+<p>By default, the options to display an information page, shutdown the computer, and reboot the computer are present. Options to launch a shell, launch the Apple recovery utility, and launch the Machine Owner Key (MOK) utility will also appear automatically if these utilities are installed. Options to launch the hybrid MBR tool and to exit from rEFInd are not displayed by default; you must edit the configuration file to enable these features, or to disable those that are displayed by default.</p>
+
+<p>To launch an OS or utility, you should select its tag and then press the Enter key or the space bar.</p>
+
+<p class="sidebar"><b>Note:</b>On UEFI-based PCs, rEFInd defaults to scanning for EFI, but <i>not</i> for BIOS, boot loaders. If you want to launch BIOS-mode OSes from rEFInd, you must edit the <tt>scanfor</tt> line in <tt>refind.conf</tt>, as described on the <a href="configfile.html">Configuring the Boot Manager</a> page. On Macs, rEFInd scans for BIOS-based OSes by default, since such configurations are a common way to launch Windows on Macs.</p>
-<p>To launch an OS or utility, you should select its tag and then press the Enter key. If you press the Insert key, rEFInd will show a menu that may hold additional options, depending on the OS type. The following figure shows the submenu for Mac OS X. You can use this menu much like the main menu; move the cursor to select the option you want to use, then press the Enter key to launch the boot loader with the selected options. Press the Esc key or select <tt>Return to Main Menu</tt> to return to the main menu.</p>
+<p>Ordinarily, rEFInd displays tags for OSes it finds on internal hard disks, external hard disks (including USB flash drives, CF disks, and so on), and optical discs. Sometimes, though, the firmware hasn't had time to fully examine these devices by the time rEFInd starts; or you might only insert or plug in the media after rEFInd appears. In these cases, you can press the Esc key to have rEFInd re-read its configuration file and re-scan your media for boot loaders. This action can take a few seconds to complete, so be patient. You can also use this feature to detect OSes if you launch a shell and use it to load a driver or edit the <tt>refind.conf</tt> file. If you regularly need to press Esc, you might look into the <tt>scan_delay</tt> configuration file option, described on the <a href="configfile.html">Configuring the Boot Manager</a> page.</p>
+
+<p>On some computers, the firmware doesn't mount external USB media unless you adjust a firmware option or use the EFI's own boot manager prior to launching rEFInd. If you don't see external media appear in rEFInd's list, consult your computer's manual or examine its firmware to locate a relevant option.</p>

+<h2>Adjusting Boot Options</h2>
+</a>
+
+<p>If you press the Insert, F2, or + key, rEFInd will show a menu that may hold additional options, depending on the OS type. (OS X and Linux are most likely to hold interesting options on their submenus.) The following figure shows the submenu for Mac OS X. You can use this menu much like the main menu; move the cursor to select the option you want to use, then press the Enter key to launch the boot loader with the selected options. Press the Esc key or select <tt>Return to Main Menu</tt> to return to the main menu.</p>

+<p>From the options submenu, you can press the Insert, F2, or + key again to edit your boot loader options. You're most likely to want to do this when booting Linux via its EFI stub loader, since you can then enter arbitrary kernel options. A simple text-mode line editor opens (shown below), enabling you to move a cursor back and forth in the line with your arrow keys, delete text, and type in new text. If you want to boot with your edited options, press the Enter key. If you decide you picked the wrong entry, press the Esc key. Note that long option lists, as shown in the figure, scroll off the edge of the screen. Moving the cursor past the screen edge scrolls the entire line of text.</p>

+
+<p>If your computer supports Secure Boot, you may find that some of your OSes and tools won't work; they'll produce <tt>Secure Boot validation failure</tt> error messages. You can overcome this problem by creating a signing key, signing your binaries with it, and adding the public version of that key to your machine owner key (MOK) list. This process is described on the <a href="secureboot.html">Managing Secure Boot</a> page.</p>

<h2>Using Keyboard Shortcuts</h2>

<p>Although most rEFInd features can be activated via fairly obvious keyboard actions, some are not obvious. <a href="#table1">Table 1</a> summarizes the keystrokes that rEFInd accepts, and the action that each keystroke invokes.</p>
