Bootloader
Grub2
Grub2 on Legacy MBR/GPT systems
GRUB2 (with or without graphical menu) will be used exclusively as the
bootloader for a Legacy/MBR or Legacy/GPT system.
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.
Grub2-efi on UEFI systems
GRUB2-efi will be used exclusively as the bootloader for a UEFI system.
By default, a new bootloader (Grub2-efi) will be written into the ESP (EFI
System Partition).
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.
Bootloader Setup
Opzioni principali del bootloader
Bootloader to use
This feature is only available to Legacy MBR/BIOS systems. Users of UEFI
systems will not see this option here.
Boot device
Don't change this unless you really know what you are doing
Delay before booting the default image
This text box 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 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 root and the
password is the one chosen hereafter.
Password
Choose a password for the bootloader (optional)
Password (again)
Retype the password and DrakX will check that it matches with the one set
above
Advanced
Enable 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
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.
Enable Local APIC
Here you can set Local APIC, which manages all external interrupts for a
specific processor in an SMP system
Bootloader Configuration
Default
The operating system to be started up by default.
Append
This option lets you pass information to the kernel or tell the kernel to
give you more information as it boots.
Probe foreign OS
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,
then untick the Probe Foreign OS option.
Advanced
Video 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
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 Ok if you are sure you understand the
implications, and wish to proceed.
Other Options
Usare un bootloader esistente
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.
Installing Without a Bootloader
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.
