Se preferisci impostazioni del bootloader diverse da quelle scelte in automatico dall'installer puoi modificare da qua. Potresti già avere altri sistemi su questa macchina. In tal caso puoi decidere se aggiungere Mageia al tuo bootloader esistente o permettere a Mageia di crearne uno nuovo. The Mageia graphical menus are nice :

By default, Mageia writes a new GRUB (legacy) bootloader into the MBR (Master Boot Record) of your first hard drive. If you already have other operating systems installed, Mageia attempts to add them to your new Mageia boot menu. Mageia adesso offre GRUB2 come bootloader opzionale oltre a GRUB legacy e Lilo. Linux systems which use the GRUB2 bootloader are not currently supported by GRUB (legacy) and will not be recognized if the default GRUB bootloader is used. La migliore soluzione è utilizzare GRUB 2 che è disponibile durante l'installazione.

If you decide to use an existing bootloader then you will need to remember to STOP at the summary page during the installation and click the Bootloader Configure button, which will allow you to change the bootloader install location. Do not select a device e.g."sda", or you will overwrite your existing MBR. You must select the root partition that you chose during the partitioning phase earlier, e.g. sda7. Per essere chiari, sda è il dispositivo, sda7 la partizione su quel dispositivo. Go to tty2 with Ctrl+Alt+F2 and type df to check where your / (root) partition is. Ctrl+Alt+F7 takes you back to the installer screen. The exact procedure for adding your Mageia system to an existing bootloader is beyond the scope of this help, 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 have very limited disk space for the / partition that contains /tmp, click on Advanced and check the box for Clean /tmp at each boot. This helps to maintain some free space.

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