[Résolu] Restauration d'une table GPT ou de GRUB

Bonjour à tous,

J'ai réalisé un live usb de Gparted manuellement en suivant les instructions données sur ce site :
http://gparted.org/liveusb.php

Comme je suis curieux et que j'aime comprendre, j'ai choisi la méthode manuelle :
GNU/Linux Method B: Manual

Il se trouve qu'elle fonctionne parfaitement bien cette clé ! Je réussis à booter dessus et à utiliser Gparted tout à fait comme je le souhaitais.

Le problème maintenant :

Lorsque j'enlève la clé usb et que je souhaite booter sur Ubuntu comme d'habitude. J'obtiens un écran noir avec un curseur blanc clignotant en haut à gauche de l'écran. Aucune possibilité d'interagir avec le pc (pas de clavier, pas de souris, etc).

En rebootant sur mon live usb Gparted, je me rends compte que mes partitions sont intactes. Je pense donc que mon problème vient de Grub ou du GPT. J'ai probablement fait une mauvaise manipulation à l'étape 5 en rendant la clé usb bootable.

Lors du lancement du script makeboot.sh, j'ai suivi toutes les options par défaut. Et notamment, lors de l'écriture du MBR sur la clé. Je pensais que le script écrirait le MBR sur la clé USB et laisserait intacts mes deux disques sda et sdb. (clé usb = sdc)

Est ce qu'à ce stade, quelqu'un pourrait m'aider ? J'imagine qu'il faut reconstruire une table GPT sur le disque sda. Sachant que ce genre de manipulation ne laisse aucun droit à l'erreur, je sollicite votre aide svp pour ne pas perdre mes données.

Voici des infos sur mon partitionnement :
sda :
Partition             Système de fichiers      Taille                    Utilisé            Inutilisé           Drapeaux
/dev/sda1           fat 32                            512Mio                 4,37Mio         507,63Mio      boot,esp
/dev/sda2           ext4                              207,15Gio            135,48Gio     71,67Gio         
/dev/sda3           linux-swap                    15,92Gio              0,0o              15,92Gio       

sdb :
Partition             Système de fichiers      Etiquette               Taille                    Utilisé            Inutilisé           Drapeaux
/dev/sdb1           ext4                              DATA                    931,51Gio            341,84Gio     589,67Gio     

En complément au cas où : sdc :
sdc :
Partition             Système de fichiers      Point de montage               Taille                    Utilisé            Inutilisé           Drapeaux
/dev/sdc1           fat 32                            /lib/live/mount/medium       1,83Gio                232,44Mio     1,60Gio          boot
     
N'hésitez pas si besoin d'autres infos
Par avance merci à vous

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file rename-ms-efi


=================== Blockers in case of suggested repair
The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. This will enable this feature. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode.


=================== Advice in case of suggested repair
The boot of your PC is in Legacy mode. You may want to retry after changing it to EFI mode.
Alternatively, you may want to retry after deactivating the [Separate /boot/efi partition:] option.
Do you want to continue?


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda1/efi/.../grub*.efi file!

The boot of your PC is in Legacy mode. You may want to retry after changing it to EFI mode.


=================== User settings
The settings chosen by the user will not act on the boot.

Ton installation de Ubuntu parait intacte. Le souci c'est que le "Boot mode" de ton système UEFI est sur Legacy (mode non-EFI) alors qu'il faut qu'il soit sur UEFI.
Peux-tu indiquer quel est le modèle de ton ordi et son fabricant ?

Re : [Résolu] Restauration d'une table GPT ou de GRUB

Il s'agit d'un pc portable assemblé par une société française. Il n'a donc pas de marque particulière. L'installation d'Ubuntu a également été réalisée par cette société (possibilité d'ordi sans OS voire de tout autre système d'exploitation au choix).

Je pense que le boot en legacy mode est dû à la clé usb. Il semble que Unetbootin crée un démarrage en legacy mode. J'ai trouvé l'utilitaire Rufus qui permet de créer un live usb avec une table GPT et un démarrage en UEFI. Je propose de tester le boot-repair avec un nouveau live usb créé avec rufus. (Pour info, j'ai déjà tenté un boot-repair avant de poster sur le forum mais un message d'erreur m'indiquait de booter en UEFI mode).

Par ailleurs, le boot en legacy est peut être dû aussi à ma mauvaise manipulation du makeboot.sh lors de la création de ma clé Gparted ?

Qu'en penses-tu ?

Re : [Résolu] Restauration d'une table GPT ou de GRUB

malbo,

J'ai fait le test que j'ai proposé. ça n'a pas fonctionné, car c'est effectivement mon système qui est en Legacy, et non pas seulement la clé.

En relisant ton message, j'ai compris que je devais changer le mode de boot dans mon bios. Eh bingo ça marche ! J'ai retrouvé mon Ubuntu habituel.

En revanche, je n'ai pas compris comment mon bios s'est retrouvé configuré pour booter en legagy. Serait-il possible qu'écrire une table MBR sur la clé usb ait pu changer d'une manière ou d'une autre le mode de boot du bios ? J'ai du mal à y croire...

Ou alors tout simplement c'est moi qui ait modifié ce mode de boot en allant fouiller dans les paramètres du bios pour modifier l'ordre de boot et mettre la clé usb en haut de la liste ? C'est bizarre aussi car je sais bien que mon système est sensé démarrer en UEFI... 

En tout cas, tout fonctionne dorénavant. Merci pour ton aide !!
