<para>GRUB2 (with or without graphical menu) will be used exclusively
as the bootloader for a Legacy/MBR or Legacy/GPT system.</para>

<para>By default, a new bootloader will be written into either the MBR
(Master Boot Record) of your first hard drive or in the BIOS boot
partition.</para>

<listitem>
<para>GRUB2-efi will be used exclusively as the bootloader for a UEFI
system.</para>
</listitem>
<listitem>
<para>By default, a new bootloader (Grub2-efi) will be written into
the ESP (EFI System Partition).</para>
<para>If there are already UEFI-based operating systems installed on
your computer (Windows 8 for example), the Mageia installer will
detect the existing ESP created by Windows and add grub2-efi to it. If
no ESP exists, then one will be created. Although it is possible to
have several ESPs, only one is required, whatever the number of
operating systems you have.</para>

default operating system is started up.</para>
</listitem>
<listitem>
<para><emphasis role="bold">Security</emphasis></para>
<para>This allows you to set a password for the bootloader. This
means a username and password will be required when booting in order
to select a booting entry or change settings. This is optional, and
most people are not likely to have a need for it. The username is
<literal>root</literal> and the password is the one chosen
hereafter.</para>

<para><emphasis>Enable ACPI</emphasis></para>
<para>ACPI (Advanced Configuration and Power Interface) is a
standard for power management. It can save energy by stopping unused
devices. Deselecting it could be useful if, for example, your
computer does not support ACPI or if you think the ACPI
implementation might cause some problems (for instance random
reboots or system lockups).</para>
</listitem>

<para><emphasis>Enable SMP</emphasis></para>
<para>This option enables/disables symmetric multiprocessing for
multi-core processors</para>
</listitem>
<listitem>
<para><emphasis>Enable APIC</emphasis></para>
<para>Enabling this gives the operating system access to the
Advanced Programmable Interrupt Controller. APIC devices permit more
complex priority models, and Advanced IRQ (Interrupt Request)
management.</para>
</listitem>
<listitem>
<para><emphasis>Enable Local APIC</emphasis></para>
<para>Here you can set Local APIC, which manages all external
interrupts for a specific processor in an SMP system</para>

<listitem>
<para><emphasis>Do not touch ESP or MBR</emphasis></para>
<para>Select this option if you don't want a bootable Mageia, but
would rather chain-load it from another OS. You will get a warning
that the bootloader is missing. Click<emphasis> Ok</emphasis> if you
are sure you understand the implications, and wish to

<section>
<title>Using an existing bootloader</title>
<para>The exact procedure for adding Mageia to an existing bootloader is
beyond the scope of this documentation. However in most cases it will
involve running the relevant bootloader installation program, which
should detect Mageia and automatically add an entry for it in the
bootloader menu. See the documentation for the relevant operating
system.</para>
</section>
<section>
<title>Installing Without a Bootloader</title>
<para>While you can opt to install Mageia without a bootloader (see
section 2.1 Advanced), this is not recommended unless you absolutely
know what you are doing, as without some form of bootloader your
operating system will be unable to start.</para>
</section>
<section>
<title>Add or Modify a Boot Menu Entry</title>
<para>To do this you need to manually edit
<filename>/boot/grub2/custom.cfg</filename> or use the software
<application>grub-customizer</application> tool instead (available in
the Mageia repositories).</para>
<note>
<para>For more information, see: <link ns4:href="https://wiki.mageia.org/en/Grub2-efi_and_Mageia">https://wiki.mageia.org/en/Grub2-efi_and_Mageia</link></para>
