[Resolu]-Grub ne se lance pas

Bonjour,
Soucis avec mon PC. Suite à un crach d' origine inconnu, J' ai réinstallé Xubuntu 18.04. Au démarrage du PC, je n' ai plus accès au Grub. Le PC démarre directement sur Xubuntu. De plus, la partition sda2 contient Win 10.
Pour info, la commande os-prober ne me ramène rien, même pas Xubuntu.
La commande fdisk -l, trouve toute les partitions comme indiqu é ci-dessous:

Disque /dev/sda : 465,8 GiB, 500107862016 octets, 976773168 secteurs
Unités : secteur de 1 × 512 = 512 octets
Taille de secteur (logique / physique) : 512 octets / 4096 octets
taille d'E/S (minimale / optimale) : 4096 octets / 4096 octets
Type d'étiquette de disque : gpt
Identifiant de disque : B153DE2B-F747-4315-97E3-EB06F3405527

Périphérique     Début       Fin  Secteurs Taille Type
/dev/sda1         2048   1050623   1048576   512M Système EFI
/dev/sda2      1050624 192667647 191617024  91,4G Données de base Microsoft
/dev/sda3    909416448 973748223  64331776  30,7G Système de fichiers Linux
/dev/sda4    192667648 909416447 716748800 341,8G Données de base Microsoft
/dev/sda6    973748224 976771071   3022848   1,5G Partition d'échange Linux

Les entrées de la table de partitions ne sont pas dans l'ordre du disque.

Plus embêtant encore, je n' arrive plus à entrer dans le bios?
J' ai peur que mon PC soit comme moi, bon pour la retraite.
Cordialement
PS: Ce qui m' intrigue, c 'est que Sda2 en type m' annonce Donnée de base Microsoft alors que Sda3 en type m' annonce Système de fichiers Linux.

Alors la première chose à faire est de contrôler l'état du disque.
                       En session installée :
a) Installer l'utilitaire permettant de voir l'état du disque :

sudo apt-get install --no-install-recommends smartmontools

  - -
b) Lire les données SMART :
faire sans ajouter de chiffre :

sudo smartctl -s on -S on -o on -a /dev/sda

et en donner le retour complet et entre balises-code.




La seconde remarque est qu'on ne voit plus de partition MSR. Cf. extrait de la documentation Microsoft avec traduction
et mes commentaires au 13/09/2016.



Enfin

Plus embêtant encore, je n' arrive plus à entrer dans le bios?

L'accès au bios de certains ordis est subordonné à la présence de partitions constructeur sur le disque. Peut-être est-ce le cas du tien ?
  Donne le nom complet du modèle, pour que les spécialistes puissent te conseiller.

Oui, et alors ?

Pour ce qui est du bios, la touche F12 est à utiliser pour les Pacard Bell. Mon PC est un EasyNote TE69KB séries.
Enfin, en disant que je suis intrigué par la formulation des partitions, c' est tout simplement parce que dans un cas, on annonce un disque de données et dans l' autre cas, on parle de système alors que les deux disques sont dédiés à des OS. Rien de plus.

Re : [Resolu]-Grub ne se lance pas

Ton disque est encore sain.     Pour le faire durer, évite ces sessions courtes :

  9 Power_On_Hours          -       5086
 12 Power_Cycle_Count       -       6993
194 Temperature_Celsius     -       27

= =


  C'est à juste titre que tu t'étonnes de cette hétérogénéité de la sortie de

sudo fdisk -l
/dev/sda2       Données de base Microsoft
/dev/sda3       Système de fichiers Linux

Il serait plus cohérent d'avoir
     soit
/dev/sda2       Système de fichiers Microsoft
/dev/sda3       Système de fichiers Linux

     soit
/dev/sda2       ntfs
/dev/sda3       ext4

Tu peux tester aussi

sudo parted -l

= =


Tu devrais lire les messages #1 à #31 :
même pc que le tien, multi-boots réussis, d'abord sur DDE, puis sur le HDD interne.
  casp3r27200 y précise :

accès bios avec le F2 (sans le bouton fn)

F2  - et non F12 qui sert à autre chose.

= =


Reste le problème de la disparition de la partition MSR :
  J'ignore s'il est possible, malgré ce qu'en dit Microsoft, de rétablir Windows10 sans écraser toutes les partitions de ton disque à GPT, après l'indispensable sauvegarde de tes données.

  De toute façon, les spécialistes auront besoin d'un rapport boot-info pour t'éclairer davantage.
NE fais PAS pour l'instant de "réparation recommandée".

(debug) reinstall grub2 place-in-MBR no-BIOS_boot (sda3)


=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub2 of sda3 into the MBR of sda.
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot


=================== Blockers in case of suggested repair
GPT détecté. Veuillez créer une partition BIOS-Boot (>1MB, système de fichiers non formaté, drapeau bios_grub). Cela peut être réalisé via des outils tels que Gparted. Puis réessayez.
Alternativement, vous pouvez ré-essayer après avoir activé l'option [Partition /boot/efi séparée :].


=================== Advice in case of suggested repair
EFI détecté. Vous souhaiterez peut-être ré-essayer après avoir activé l'option [Partition /boot/efi séparée :].
Voulez-vous continuer ?


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

Merci encore en attendant d' autres infos.

Re : [Resolu]-Grub ne se lance pas

Bonjour à tous,
N' ayant pas de nouvelles de spécialistes du démarrage en dual boot, j' ai réglé le problème à la hussarde. En fait, pour le démarrage avec une partition GPT, il semble nécessaire d' avoir à la base du disque dur un partition vide et non formaté de 1 MIO. Ne sachant pas comment faire, j' ai réinstallé Win 10 et après avoir fait de la place avec Gparted, j' ai réinstallé Xubuntu ainsi que toutes les applications que j' utilisai. Il est indispensable d' effectuer une sauvegarde de toutes les données avant d' effectuer ce genre de manipulation.
Bon, voila une solution. Elle est peut satisfaisante mais elle dépanne.
Cordialement
