<title>With an UEFI system</title>
<para>With an UEFI system, the user interface is slightly different as you
cannot choose the boot loader since only Grub2-efi is available. </para>

</imageobject>
</mediaobject>
<para>If Mageia is the first system installed on your computer, the
installer created an ESP (EFI System Partition) to receive the bootloader
(Grub2-efi). If there was already UEFI operating systems previously
installed on your computer (Windows 8 for example), the Mageia installer
detected the existing ESP created by Windows and added grub2-efi. Although
it is possible to have several ESPs, only one is advised and enough
whatever the number of operating systems you have.</para>
<para>Don't modify the "Boot Device" unless really knowing what you
do.</para>
