[Essai] efibootmgr depuis 14.10 en dual-boot avec W8
Manip faite en virtualisation (avec VMware Player) : installation en mode EFI de Ubuntu 14.10 64 bits en cohabitation avec Windows 8 préinstallé en mode EFI, investigations sur l'UEFI vu depuis le Ubuntu installé.
Je fais un Boot-Info pour garder un panorama complet de l'install :

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda5, using the following options: sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s fix-windows-boot use-standard-efi-file
=================== Advice in case of suggested repair
Veuillez désactiver SecureBoot dans le BIOS. Puis réessayez.Voulez-vous continuer ?
=================== Final advice in case of suggested repair
Si votre ordinateur redémarre directement sur Windows, essayez de changer l'ordre de démarrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut de l'amorceur Windows.
Par exemple, vous pouvez démarrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateur :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi
=================== User settings
The settings chosen by the user will not act on the boot.
1) commande - à passer depuis une session du Ubuntu installé - permettant de visualiser l'UEFI :
sudo efibootmgr -v
[sudo] password for malbo:

On peut noter qu'on retrouve exactement ce qu'on peut voir dans la partie "efibootmgr -v" du rapport Boot-Info.
2) déchiffrage de la ligne Boot0001 correspondant à l'entrée "ubuntu" dans le menu de l'UEFI :
Boot0001* ubuntu HD(2,96800,32000,1ccc0f6b-032a-45c8-b25e-b50e2dc5ee8d)File(\EFI\ubuntu\shimx64.efi)
a) HD(2 : c'est la partition 2 du disque (donc sda2)
b) 96800 : c'est le secteur de démarrage de la partition exprimé en Hexadécimal.
Vérification : on passe la commande "sudo fdisk -l" qui donne le résultat suivant :
sudo fdisk -l
Disk /dev/sda: 60 GiB, 64424509440 bytes, 125829120 sectors
Units: sectors of 1 * 512 = 512 bytes

/dev/sda2 616448 821247 204800 100M EFI System
/dev/sda3 821248 1083391 262144 128M Microsoft reserved

/dev/sda6 99069952 102975487 3905536 1,9G Linux swap
La partition sda2 commence au secteur 616448 (exprimé en décimal), ce qui correspond bien à 96800 exprimé en HEXA
c) 32000 : c'est le nombre de secteurs de la partition, exprimé en Hexadécimal.
Dans le résultat de "sudo fdisk -l", on voit que ce nombre (colonne "Sectors") pour la partition sda2 est 204800 exprimé en décimal, ce qui correspond bien à 32000 exprimé en HEXA
d) 1ccc0f6b-032a-45c8-b25e-b50e2dc5ee8d : c'est un identifiant de la partition. On peut vérifier qu'il s'agit bien de l'identifiant de la partition sda2 en passant la commande "sudo blkid" et en examinant le résultat obtenu :
sudo blkid
/dev/sda1: LABEL="RM-CM-)cupM-CM-)ration" UUID="B0C0E8A5C0E872D0" TYPE="ntfs" PARTLABEL="Basic data partition" PARTUUID="aee3c406-eb85-4d2e-adc3-ab50b8420b2e"
/dev/sda2: UUID="3EE8-FABA" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="1ccc0f6b-032a-45c8-b25e-b50e2dc5ee8d"

/dev/sda5: UUID="6a2b269f-d13f-4cbe-bdba-62ef91e4c44f" TYPE="ext4" PARTUUID="97033c4d-66ba-4c8c-8937-07209ee9c874"

Dans les résultats de cette commande, je trouve bien que c'est l’identifiant PARTUUID de sda2 dans la ligne suivante :
/dev/sda2: UUID="3EE8-FABA" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="1ccc0f6b-032a-45c8-b25e-b50e2dc5ee8d"
e) File(\EFI\ubuntu\shimx64.efi) : c'est l'emplacement du fichier d'amorçage de Ubuntu sur la partition
On peut voir dans cet extrait du Boot-Info que ce fichier existe bien à cet emplacement sur la partition sda2 :
sda2: __________________________________________________________________________
File system: vfat
Boot sector type: Windows 8/2012: FAT32
Boot sector info: No errors found in the Boot Parameter Block.
Operating System:
Boot files: /EFI/Boot/bootx64.efi /EFI/ubuntu/MokManager.efi
/EFI/ubuntu/grubx64.efi /EFI/ubuntu/shimx64.efi
/EFI/Microsoft/Boot/bootmgfw.efi
/EFI/Microsoft/Boot/bootmgr.efi
/EFI/Microsoft/Boot/memtest.efi
3) déchiffrage de la ligne Boot0002 correspondant à l'entrée "Windows Boot Manager" dans le menu de l'UEFI :
Boot0002* Windows Boot Manager HD(2,96800,32000,1ccc0f6b-032a-45c8-b25e-b50e2dc5ee8d)File(\EFI\Microsoft\Boot\bootmgfw.efi)WINDOWS.........x...B.C.D.O.B.J.E.C.T.=.{.9.d.e.a.8.6.2.c.-.5.c.d.d.-.4.e.7.0.-.a.c.c.1.-.f.3.2.b.3.4.4.d.4.7.9.5.}....................
C'est idem que pour l'entrée "ubuntu", ce qui est normal puisque les deux entrées "pointent" sur la partition sda2 sauf pour l'emplacement du fichier d'amorçage qui est \EFI\Microsoft\Boot\bootmgfw.efi sur la partition sda2. On peut voir dans l'extrait du Boot-Info ci-dessus que ce fichier est bien à l'emplacement indiqué.
