Introduction
UEFI est le nom commun pour les standards EFI et UEFI. Cependant, il ne prend pas en compte la vielle version EFI v1, ou la version à part faite par Apple.
Ordinateurs concernés
Ce guide vise à l'installation de Manjaro sur une machine ayant UEFI d'activer, le démarrage sécurisé (Secure Boot) de désactive et utilisant le partitionnement GPT (GUID Partition Table).
Pour les machines possédant plusieurs systèmes d'exploitation, le système de partition EFI qui est déjà présent (ou qui sera créé par la suite), peut être tour à fait partager parmi les autres installations de Linux présentes.
Les Étapes
Préparons ce dont nous avons besoin
- 1. Commencez part télécgharger votre version de Manjaro préférée (XFCE, Openbox, Cinnamon, KDE, etc.), il est cependant obligatoire de prendre une architecture 64 bits.
- 2. Gravez le fichier .iso sur une clef USB ou un DVD. En cas de problèmes, consultez ce guide pour plus de détails.
- 3. Consultez les paramètres de votre BIOS : UEFI doit être obligatoirement activé et Secure boot (démarrage sécurisé) désactivé.
- 4. Démarrez sur votre clef ou DVD et utilisez le menu en face de vous (rEFInd) pour choisir avec quels pilotes GPU vous voulez installer Manjaro (libres ou propriétaires) :
* Démarrez Manjaro Linux ... (default) - Choisira les pilotes libres (open source). * Boot Manjaro Linux ... (nonfree) - Cette option sélectionnera les pilotes propriétaires pour Nvidia ou ATI
Installateur Graphique
Pour utiliser cet installateur, sélectionnez Install Manjaro (Installer Manjaro) depuis l'écran de bienvenue proposé par Manjaro. Il est possible d'y accéder également depuis le bureau en cliquant sur l'icône prévue à cet effet.
Depuis l'ESP (EFI System Partition : système de partition EFI), qui enregistrera notre binaire GRUB de type EFI, une partition de 512 MB en fat32 peut être créée (depuis l'écran de modification des disques) et montée sur /boot/efi
Si vous essayez d'installer Manjaro à côté d'un autre système, alors une partition EFI déjà présente peut également être utilisée.
Installateur à l'interface en lignes de commandes (CLI)
- 5-b. Ouvrez le terminal et tapez :
- 6. Nous sommes à présent dans l'installateur à l'interface par lignes de commandes (CLI).
- 7. Choisissez 1. Set date and time - an easy intuitive configuration (Configurez la date et l'heure - une option facile et intuitive).
Préparation du disque
* When you click 2. Partition Hard Drives, you get a dialog saying "Do you want to use GUID Partition Table (GPT)", choose Yes. * Partition your disk(s) as you want (Instructions on manually partitioning are beyond the scope of this guide, some deatils are available here). * Important Step: Create a 50~250MB EFI Partition, mine is 100MB (code: ef00)
Setting filesystem mount points
* After the partitioning is done, go to 4. Set Filesystem Mountpoints. * Important Step: Format the EFI Partition you created as VFAT and mount on /boot/efi
Installation
- 9. Choose 3. Install system and wait...
- 10. Now, go to 4. Configure System and configure it the way you like (username, password, mirrorlist, system-name, ...).
- 11. When you are done, go to 5. Install bootloader. Choose EFI_x86_64 > GRUB (2) UEFI x86_64, DON'T select BIOS GRUB.
- 11.1 It will ask to format the EFI Partition you created earlier as FAT32, yes can be chosen.
- 12. If it gives a error in the final stages saying "efivars kernel module was not properly loaded", don't worry, the system will work fine!
- 13. If the installer asks you about copying grub/efi files to another folder in order to maintain compatibility in some systems, choose Yes.
- 14. Click 6. Quit
- 15. Shutdown, remove the DVD or USB, and boot. Your system should appear now!
Switching from BIOS to UEFI
1) You need to create an ESP (EFI System Partition).
It is a FAT32 partition which has the .efi files for booting, which you can create using gparted or gdisk. (Size at least 200-300 MiB.) Ensure the flags `boot` and `esp` are set on this partition.
You should also install/check whether following packages are present-
1. efibootmgr 2. dosfstools 3. grub
2) Create the /boot/efi directory
3.) Mount the EFI partition as /boot/efi
sudo mount /dev/sdXY /boot/efi
X = Alphabet of the drive = a,b,c ... Y = Partition number of the EFI partition = 1,2,3,4...
Example - /dev/sda4
4.) Install Grub according to UEFI
5.) Update Grub configuration file.
path '/boot/grub' is not readable by Grub on boot. Installation is impossible. Aborting
Then you will need to chroot as described here, and then perform Step 5 again.
EFI variables are not supported on this system.
then you could load the efivarfs module :

Dual booting with Windows
In such cases rEFInd can be used.
There are two ways to install rEFInd-
1.Install rEFInd from its website [2] (detailed) or install using pacman(preferred)-
Files will be present in /usr/share/refind .
2.Or using the instructions on the rEFInd website: [3]
Instructions
The refind-install command can be used to automatically install rEFInd (the EFI partition may need to be mounted for this to work). See the Arch wiki for more details.
Manual install
Inside the refind folder (/usr/share/refind), copy the files and folders to-
/boot/efi/EFI/Boot/
You need to copy these files to the Boot folder on your EFI partition, and the Boot folder itself will be present inside the EFI folder on the EFI Partition, so take note of it.
You can check which partition is your ESP using Gparted; find which partition is formatted as fat32 and has size around 200mb-1gb.
Can mount it as /boot/efi by
X=a,b,c... N=1,2,3... These depend on which partition your ESP is present which can be obtained via Gparted as mentioned earlier.
Now inside the /boot/efi/EFI/Boot/ folder, there should already be a file present-
bootx64.efi
You can rename it as windows.bootx64.efi Then you can rename refind_x64.efi to bootx64.efi
The bootx64.efi files boot by default, hence rEFInd should now boot by default, and detect grubx64.efi(linux-manjaro) and efibootmgfw.efi (windows) automatically.
So it could be like-
/boot/efi/EFI/Manjaro/grubx64.efi
rEFInd would use this file for booting Manjaro.
If you do not have this file or folder, try-
to create /boot/efi/EFI/Manjaro/grubx64.efi

An alternative: chainloading via GRUB
An entry can be added to
menuentry 'Windows8 (UEFI)' { insmod ntfs set root=(hd0,gpt4) chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi boot }
In this case (hd0,4) or /dev/sda4 is the EFI System partition where the Windows bootloader is present.
After adding the above entry, running sudo update-grub updates the GRUB configuration file so that an entry named Windows8 (UEFI) is added to the GRUB boot menu.
Related Forum thread: [4]
The chainloading will fail on some hardware (Lenovo Ideapad 110) with the "invalid signature" message - the Refind method will still work.
Extras
Using Rufus on Windows to create installation media
Rufus users can use the following settings:
* Click on the DVD icon and load your .iso * In the menu left of the DVD icon, select DD Image * Device: "choose your USB" (Attention: choose correctly, the device selected here will be formatted!!!) * Partition scheme: GPT partition scheme for UEFI computer * File system: FAT32 * Cluster size: "Don't modify" * Volume label: "Don't modify" * Click Start, and you are done (takes 2~5 min to complete).
