-<p>If your computer supports Secure Boot, you may find that some of your OSes and tools won't work; they'll produce <tt>Access Denied</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>Adjusting Boot Options</h2>

+
+<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>
