La ligne Grub pour charger Windows ne boot pas

BJ69 · par **BJ69** » 06 févr. 2021 06:42

Bonjour

j'ai un system récent UEFI composé d'un disk GPT avec W10 pro et 2 Linux (Mint 20 et elementary OS 0.5) + 1 disk data 2To à coté

Au niveau UEFI de la machine, je peux booter soit sur Windows 10 - OK, soit sur le Grub de la partition Mint et là j'ai les entrées linux et une de windows 10 qui ne fonctionne pas (Ecran noir)

Ce n'est pas bloquant mais je me demande pourquoi le boot grub sur Windows (chainloader) me donne un écran noir.
J'ai essayé de configurer l'entrée Windows en dur ou de le reprendre depuis les osprober sans succes.

Dès que je sélectionne l'entrée Windows l'écran reste noir. On dirait que le bootmgfw.efi se bloque

Précision : j'ai installé d'abord w10 depuis une clé bootable sur le SSD vierge (avec ses 4 partitions EFI, MR, NTFS et recovery) puis les linux sur 2 autres partitions 5 et 6 en clonant des linux provenant d'autres machines (j'ai modifié les uuid et réglé les pbm de linux)

je met le résultat du BOOTINFO :

Si je lis bien ton disque sda est en GPT mais le bootmgr affiché est en MBR : /bootmgr /Windows/System32/winload.exe
C'est censé pointer sur winload.efi
Je ne sais pas trop si ça peut fonctionner correctement.

Par contre je ne sais pas trop comment l'arranger.
Peut-être qu'il faudrait faire un coup de bcdboot pour remettre en .efi et voir suite.

Après je ne suis pas 100% sûr.

Merci de ta réponse.

le disque 1 est bien en gpt mais c'est pas le bootmgfw.efi de la partition efi qui renvoi ensuite au winload.exe dans la partition Windows ?

je réfléchis avant de risquer gros.... J'en ai pas mal bavé pour trouver une clé usb avec mon windows bootable en mode efi car des que je passais en mode "efi" aucune clé ne bootait. ...

Finalement, j'ai résolu le pbm. J'ai constaté en mode grub rescue que le faire de charger le boutmgfw.efi sur hd0,gpt1 ne générait pas de message d'erreur mais qu'en en sortant par exit, je bootais sur Windows.

Du coup j'ai rajouté un exit dans mon 40_custom.. comme ca :

menuentry 'Windows sur 40_custom mint avec exit apres (sur /dev/sda1)' --class windows --class os $menuentry_id_option 'osprober-efi-2621-2BD2' {
savedefault
insmod part_gpt
insmod fat
set root='hd0,gpt1'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1 2621-2BD2
else
search --no-floppy --fs-uuid --set=root 2621-2BD2
fi
chainloader /efi/Microsoft/Boot/bootmgfw.efi
exit
}
