boot menu.

<p>Mageia now also offers GRUB2 as an optional bootloader in addition to GRUB
legacy and Lilo.

<p>With an UEFI system, the user interface is slightly different as you cannot
choose the boot loader since only Grub2-efi is available.
</p>
<p>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.
</p>
<p>Don't modify the "Boot Device" unless really knowing what you do.</p>
