By default, Mageia uses exclusively: GRUB2 (with or without graphical menu) for a Legacy/MBR or Legacy/GPT system GRUB2-efi for a UEFI system. The Mageia graphical menus are nice :)

Don't modify the Boot Device unless you really know what you are doing.

With a UEFI system, the user interface is slightly different as you cannot choose between the with or without graphical menu options. If Mageia is the only system installed on your computer, the installer created an ESP (EFI System Partition) to house the bootloader (GRUB2-efi). If there are already UEFI operating systems installed on your computer (Windows 8 for example), the Mageia installer detects the existing ESP created by Windows and adds GRUB2-efi. Although it is possible to have several ESPs, only one is required (and advised), whatever the number of operating systems you have. Don't modify the Boot Device unless you really know what you are doing.

By default, and according to your system, Mageia writes one of the following: a GRUB2 bootloader either into the MBR (Master Boot Record) of your first hard drive or in the BIOS boot partition. a GRUB2-efi bootloader into the ESP If you already have other operating systems installed, Mageia attempts to add them to your new Mageia boot menu. If you don't want this behaviour, click on Next and then untick the Probe Foreign OS option

The exact procedure for adding your Mageia system 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 and add it automatically. See the documentation for the operating system in question.

If you don't want a bootable Mageia, but to chain-load it from another OS, click on Next, then on Advanced and tick the box Do not touch ESP or MBR. You will get a warning that the bootloader is missing, ignore it by clicking OK.

Delay before booting the default image: This lets you set a delay in seconds before the default operating system is started up.Security: This allows you to set a password for the bootloader. This means a username and password will be required when booting to select a booting entry or change settings. The username is root and the password is the one chosen here-after.Password: Choose a password for the bootloader.Password (again): Retype the password and DrakX will check that it matches with the one above.NaprednoEnable ACPI: 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).Enable SMP: This option enables/disables symmetric multiprocessing for multi core processors.Enable APIC: 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.Enable Local APIC: Local APIC manages all external interrupts for a specific processor in an SMP system.

Default: Operating system started up by default Append: This option lets you pass the kernel information or tell the kernel to give you more information as it boots. Probe foreign OS: see above Using a Mageia bootloader NaprednoVideo mode: This sets the screen size and colour depth to be used by the boot menu. If you click the down triangle you will be offered other size and colour depth options.Do not touch ESP or MBR: see above Using the chain loading
