Set up boot system


If you are using a UEFI system instead of BIOS, the user interface is slightly different as you cannot choose the boot loader (first drop down list) since only one is available.

This tool[48] allows you to configure the boot options (choice of the bootloader, set a password, the default boot, etc.)

It is found under the Boot tab in the Mageia Control Center labeled "Set up boot system".


Don't use this tool if you don't know exactly what you are doing. Changing some settings may prevent your machine from booting again !

In the first part, called Bootloader, it is possible if using BIOS, to choose which Bootloader to use, Grub, Grub2 or Lilo, and with a graphical or a text menu. It is just a question of taste, there are no other consequences. You can also set the Boot device, don't change anything here unless you are an expert. The boot device is where the bootloader is installed and any modification can prevent your machine from booting.

In UEFI system, the bootloader is Grub2-efi and is installed in /boot/EFI partition. This FAT32 formatted partition is common to all operating systems installed.

In the second part, called Main options, you can set the Delay before booting default image, in seconds. During this delay, Grub or Lilo will display the list of available operating systems, prompting you to make your choice. If no selection is made, the bootloader will boot the default one once the delay elapses.

In the third and last part, called Security, it is possible to set a password.

The Advanced button gives some extra options.

Enable ACPI:

ACPI (Advanced Configuration and Power Interface) is a standard for the power management. It can save energy by stopping unused devices, this was the method used before APM. Check this box if your hardware is ACPI compatible.

Enable SMP:

SMP stands for Symmetric Multi Processors, it's an architecture for multicore processors.


If you have a processor with HyperThreading, Mageia will see it as a dual processor and enable SMP.

Enable APIC and Enable Local APIC:

APIC stands for Advanced Programmable Interrupt Controller. There are two components in the Intel APIC system, the local APIC (LAPIC) and the I/O APIC. The latter one routes the interrupts it receives from peripheral buses to one or more local APICs that are in the processor. It is really useful for multi-processor systems. Some computers have problems with the APIC system which can cause freezes or incorrect device detection (error message "spurious 8259A interrupt: IRQ7"). In this case, disable APIC and/or Local APIC.

The Next screen differs depending on whether you have an BIOS or UEFI system.

  • You have a BIOS system:

    In this case, you can see the list of all the available entries at boot time. The default one is asterisked. To change the order of the menu entries, click on the up or down arrows to move the selected item. If you click on the Add or Modify buttons, a new window appears to add a new entry in the bootloader menu or to modify an existing one. You need to be familiar with Lilo or Grub to be able to use these tools.

    The Label field is freeform, write here what you want to be displayed in the menu. It matches the Grub command "title". For example: Mageia3.

    The Image field contains the kernel name. It matches the Grub command "kernel". For example /boot/vmlinuz.

    The Root field contains the device name where the kernel is stored. It matches the Grub command "root". For example (hd0,1).

    The Append field contains the options to be given to the kernel at boot time.

    If the box Default is checked, Grub will boot this entry by default.

    In the extra screen called Advanced, it is possible to choose the Video mode, an initrd file and a network profile, see the section called “Manage different network profiles”, in the drop-down lists.

  • You have a UEFI system:

    In this case, the drop-down list displays all the available entries; click on the one wanted as the default one.

    The Append field contains the options to be given to the kernel at boot time.

    In the extra screen called Advanced, it is possible to choose the Video mode.

    To set many other parameters, you can use Grub Customizer, available in the Mageia repositories (see below).

[48] You can start this tool from the command line, by typing drakboot as root.
