Message d'erreur lors du démarrage

Mario2020C

Bonjour à tous

J'ai un portable HP EliteBook Folio que j'aime bien.
Auparavant, il était monté en dual boot Windows10 et Ubuntu mais le côté Linux n'apparaissait pas lors du démarrage.
J'ai perdu cette façon de démarrage et j'aimerais bien la retrouver.

J'ai dû réinstaller Windows 10 et Linux et maintenant, voici ce qui se passe:
1- Lors du démarrage, j'ai le message suivant qui s'affiche: (voir le fichier 1 annexé)
FW Status recovery error.
System BootOrder not found. Initializing defaults.
Creating Boot entry Boot000F with label Ubuntu for file \EFI\ubuntu\shimx64.efi

Puis, après quelques secondes, mon portable continue le démarrage sous Windows 10 comme si rien n'était.

Pour retourner sous Linux, je dois, lors du démarrage, peser sur la touche F9 Boot options et suivre la procédure suivante:
Voilà quand je pèse sur F9 lors du démarrage

Ensuite j'ai le menu qui me donne que le choix suivant:
Seul choix disponible

Qui m'amène au choix EFI:
Choix EFI

D'où maintenant je peux choisir l'option Ubuntu:
Choix Ubuntu

D'où je peux choisir le fichier rubx64.efi:
Choix grubx64.efi
et qui m'amène finalement au démarrage de ma partition Ubuntu.

J'ai tenté la réparation par la partie Windows 10 mais cela n'a pas fonctionné. J'ai toujours le même message qui s'affiche au démarrage puis il continue en Windows 10.:
Outil de redémarrage de Windows 10

Finalement, voici ma configuration de mon disque dur. Vous conclurez que ma partition Linux est la dernière de 33G.:
Gestion de disque

Merci d'avance pour votre aide pour me retrouver avec un démarrage unique sous Windows 10 et aussi pouvoir peser sur F9 et sélectionner directement Ubuntu (comme auparavant) comme choix secondaire de démarrage.

Pour terminer, quel est le meilleur logiciel qui pourrait être utilisé sous Linux (et par une clé USB de démarrage) pour faire une image exacte et complète de mon disque dur (configuration de base) et ce, sur un disque dur externe afin de ne plus me retaper des jours en réinstallation de mes deux partitions. Auparavant, j'utilisais Acronis True image

Merci et bonne journée

Ben tu t'embetes à booter sur le buntu installé depuis lequel tu nous retourneras l'url fournit par boot-info (voir la doc). De là on aura tout ou presque de ce qu'il faut savoir.

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sda6,
using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file    

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.10 CurrentSession entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sda6,
using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file    

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.10 CurrentSession entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)

Donc avant, tu passais par F9 pour lancer buntu direct, c'est ça ?

Là c'est la 20.10 ; c'est une installe fraiche, une mise à niveau ?

Ce qui cloche se trouverait ci-dessous:

t'as une génération d'entrée buntu/../shimx64.efi mais quand tu t'embetes à booter c'est sur la ligne boot0000

Salut,

Ton installation est bien faite, mais ton problème vient de toute évidence de la Nvram (la zone de ton bios qui lance les OS). Si tu regardes la capture de Lucmars, on n'y voit d'entrée ni pour Windows ni pour Ubuntu dans la zone "boot order'.

Je pense qu'il faut déjà voir dans ton bios (onglet boot, mais aussi onglet avancé), si tu as moyen d'ajouter manuellement des entrées pour les deux OS.

En revanche, tu as tenté de réparer avec un logiciel du genre "grub-customizer", ce qui ne me semble pas très judicieux. Ca a juste ajouté plein de merdouilles inutiles.

On peut toujours tenter d'ajouter ces entrées depuisUbuntu avec la commande efibootmgr, mais je doute que ça se passe mieux qu'avec le processus d'installation.

Bonjour. Je suis vraiment rouillé en ce qui concerne Linux et ses termes.
J'ai finalement tenté une réinstallation complète du portable sous Windows 10 en formatant tout le disque comme un tout neuf.
Mais j'ai pris le temps de me faire une image disque avec Acronis. C'est quand même long une installation personnalisée...
L'installation s'est bien déroulée et je Bootait directement sans aucun problème.
Aussi, durant l'installation, j'ai volontairement laissé une partie de 33G non formatée, prête pour accueillir Linux Ubuntu V20.

Par la clé USB Ubuntu, j'ai fait une nouvelle installation de Ubuntu sur le disque dur en Dual-Boot et tout semblait OK.
Je me retrouve encore une fois, lors du démarrage avec le même message du début:
FW Status recovery error.
System BootOrder not found. Initializing defaults.
Creating Boot entry Boot000F with label Ubuntu for file \EFI\ubuntu\shimx64.efi

Puis, le démarrage continue pour ensuite me donner un plus gros message d'erreur ( Voir le fichier ci-joint

)

J'ai ensuite créé un fichier Boot-info qui donne ce qui suit:

boot-repair-4ppa125                                              [20201205_1928]

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sda6,
using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file    

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the Ubuntu 20.10 entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)

J'avoue que je ne crois pas avoir fait d'erreur lors de l'installation mais la, ni Windows, ni Linux ne démarre.
Merci de me répondre

Re,

Tu confirmes qu'aucun des OS ne fonctionne, même en passant par F9 ?

Mario2020C

Oui je le confirme. J'ai de plus essayé tous les choix possibles.
Je suis à me demander si c'est la configuration du bios qui est à modifier genre activer boot-secure inactif ou le genre de EFI... mais ça fonctionnait tel que présentement avant...

Re,

Procédons dans l'ordre. Quand tu passes par F9 :

1. Que se passe-t-il si tu choisis "windows boot manager" (s'il apparaît) ?
2. Parviens-tu, comme au début, à exécuter directement un fichier efi ?

1- Il me donne le choix de booter sous Windows, Boot, et Ubuntu
Dans chacun de ces choix, j'ai essayé tous les modes qui me retournent au début ou bien il redémarre et les écrans FW... réapparaissent suivis de Kernel panic....

2- OUi je me rend à chacun des fichiers efi mais il tourne en boucle comme expliqué en 1-

J'ai tenté une réinstallation totale et je suis maintenant au tout début de l'installation de Ubuntu. Je vais réessayer l'installation différemment soit en téléchargeant une autre image de Ubuntu et une nouvelle gravure sur USB.
Histoire à suivre...
Aussi, j'ai fait un reset complet d'usine du BIOS et chipset, 3 scan complet d'antivirus différents et aussi un scan du programme MRT de Microsoft. Tous n'ont rien trouvé.

ikewdu

Re,

Tiens-nous au courant du résultat de tes réinstallations.

Mario2020C

Merci de me conseiller.

J'ai tenté une réinstallation totale encore une fois.
Par contre j'ai pris soin de mettre à jour le chipset et remis les valeurs par défauts du BIOS.
Aussi, actuellement, l'option de démarrage est en mode UEFI Hybride (avec CSM).

Le disque dur a été effacé complètement et j'ai réinstallé Windows 10 avec en plus, une partition DATAS de 71G.
J'ai aussi laissé une portion inutilisé de 30G pour accueillir Ubuntu.

Puis j'ai installé cette fois-ci la version Ubuntu 20.04 (stable) qui s'est bien installé grâce à Rufus, une clé USB de 8G et aussi 2G de persistance.
Tout a bien été à part le paquet Google chrome qui m'a donné le message suivant:

Impossible d'installer le fichier: Il n'est pas pris en charge

J'ai essayé de l'installer différemment mais j'ai eu le même message.

Donc, j'ai rebooté la machine et je me suis retrouvé avec le même message du début:

FW Statut Recovery error.
System BootOrder Not Found. Initializing defautls.
Creating Boot entry Boot0006 with label ubuntu for file \EFI\ubuntu\shimx64.efi

Puis, après quelques instants, le message suivant apparait:

Désolé, Ubuntu 20.04 a rencontré une erreur interne
Envoyez un rapport d'anomalie aux développeurs?

J'ai cliqué sur Envoyé mais impossible de copier ou sauvegarder le rapport.

Au démarrage,
Impossible de redémarrer sur Windows ni sur Ubuntu. Mais mes partitions sont encore intactes.

J'ai donc réeffacé la partition Windows et refait une réinstallation de l'image.
Actuellement, je boot très bien sur Windows mais je ne vois plus ubuntu sauf qu'il est présent lorsque je regarde par el gestionnaire de disque.
Par F9, il n'est pas visible non plus.
J'imagine qu'il est possible de réactiver la partition active pour que je puisse le démarrer que par F9 comme avant mais la, j'attend vos conseils.

Re,
Peux-tu refaire un rapport boot-info pour qu'on voie concrètement la situation actuelle, qui est fonctionnelle pour W10 ?

Edit. As-tu testé cette solution de Yorick Reuvekamp ? https://askubuntu.com/questions/1154080/19-04-hp-system-bootorder-not-found-initializing-defaults-rebooting-inst

Mario2020C

Le rapport Boot-info va suivre.
J'ai tenté de démarrer à partir de l'ordinateur sous ubuntu mais pas possible.
J'ai démarré avec la clé usb sous ubuntu 20.04 mais curieusement, il m'affiche l'écran de fond de ubuntu 20.10 ??
De plus, il est super lent. Ouvrir Firefox prend plus de 2 minutes et ouvrir une fenêtre ou un programme est super lent.
C'est comme si la lecture sous usb se fait selon la norme usb 1.0...
Peut-être que ma clé de 8G n'est pas assez rapide.
Je viens de graver une nouvelle clé 32G Kingston.

Je suis allé voir vos liens et j'ai retenu le dernier qui m'a aussi amené au lien suivant:
MBR ou GPT
Ce lien m'explique que j'ai tout avantage à garder le lien GPT et je serais plutôt porté à effacer le MBR.
Effectivement, mon disque dur est un SSD et suite à la lecture, gdisk me donne exactement le même résultat tel que décrit dans l'article soit:

Partition table scan:
MBR: progressive
BSD: Not present
APM: Not present
GPT: Present
Found valid GPT with protective MBR ; using GPT.
Command (? for Help)

Je me pose la question à ce qui serait le meilleur choix.

Devrais-je supprimer l'option MBR ou GPT?

Mario2020C

P.S. Le démarrage à partir de ma nouvelle clé USB 32G Kinston avec 5G de persistance me donne une navigation et des applications très fluides.

Voici mon dernier boot-info
Selon le tutoriel, alors que j'ai démarré avec la clé USB:
1.2 Installation.
1.2.1 Cas où au moins un ubuntu installé sur disque est opérationnel (J'ai fait aussi un boot-info selon l'autre puisque je n'étais pas certain duquel choisir exactement)

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sda6,
using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file    

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sda6,
using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file    

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)

Re,

Je ne comprends pas la situation : dans le premier cas, veux-tu dire que tout fonctionne ? Et dans le second cas, c'est le contraire ?
