réparation grub

Bonjour, j'ai un pc portable Dell sur lequel j'ai installé window 7 et 10 et ubuntu en multi-boot sur un disque SSD partitionné.
Tout fonctionnait bien mais j'ai eu la mauvaise idée de vouloir modifier  un paramètre dans grub ça c'est mal passé j'ai paniqué et tenté de faire une réparation puis une autre et finalement j'ai planté le pc.maintenant au démarrage j'ai le message suivant :
GNU GRUB Version 2.04
Minima BASH-like line editing is supported. For the first word, TAB list possible command completions, anywher else TAB list possible device or file completions.

mon anglais étant limité, je suis complètement perdu.
Puis- tenter d'utiliser boot repair à partir d'une clé usb ?

Par avance merci pour votre aide.

Re : réparation grub

Bonsoir.
Dans un premier temps, faire un état des lieux avec boot-info serait préférable. Poste le lien qui sera généré.

Si tu te souviens du paramètre modifié, indique-le, cela permettra de le retrouver plus vite dans le boot-info.

Re : réparation grub

Bonjour,
Merci  geole pour ta réponse rapide.

Voici le lien boot-info  http://paste.ubuntu.com/p/FHyrHqcmp8/

Initialement je voulais modifier le titre du boot via le gestionnaire Grub et j'ai eu un message me disant que Grub avait rencontré un pb et du coup j'ai " trifouillé" dans les menus déroulant sans prendre garde de mémoriser les choix avant , je ne sais pas trop dire quels sont les paramètres que j'ai modifié

Re : réparation grub

Bonjour

D'après le boot-info

===================================== UEFI =====================================
This live-session is not in EFI-mode.

Donc boot à partir du MBR

============================== Boot Info Summary ===============================
 => Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of 
    the same hard drive for core.img. core.img is at this location and looks 
    for (,msdos6)/boot/grub. 

Cela va donc continuer dans la partition 6

sda6: __________________________________________________________________________
    File system:       ext4
    Operating System:  Ubuntu 20.04.3 LTS
    Boot files:        /boot/grub/grub.cfg /etc/fstab /etc/default/grub 
                       /boot/grub/i386-pc/core.img

Core.img y est bien présent...
La suite sera donc le  fichier de paramétrage  du grub

====================== sda6/boot/grub/grub.cfg (filtered) ======================


========================== sda6/etc/fstab (filtered) ===========================

On voit qu'il n'en existe plus aucun .......

Regardons donc ces fameux paramètres modifiés

====================== sda6/etc/default/grub (filtered) =======================
GRUB_DEFAULT="saved"
GRUB_TIMEOUT_STYLE="hidden"
GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
export GRUB_COLOR_NORMAL="light-gray/black"
export GRUB_COLOR_HIGHLIGHT="magenta/black"
GRUB_SAVEDEFAULT="true"

A priori, je n'ai pas vu d'erreurs de codification évidente.
Regardons ce que propose boot-repair

The default repair of the Boot-Repair utility would purge (in order to fix customized files) and reinstall the grub2 of sda6 into the MBRs

Conclusion : Fais la réparation recommandée. Cela devrait refabriquer le fichier de paramétrage du grub.

=============================== StdErr Messages ================================

File descriptor 63 (pipe:[57905]) leaked on lvs invocation. Parent PID 4569: /bin/bash

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to fix customized files) and reinstall the grub2 of
sda6 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix     

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your BIOS boot on sda (ATA SanDisk SSD PLUS) disk!

Re : réparation grub

Voilà c'est fait ! voici le lien http://paste.ubuntu.com/p/XDkyZ97HyN/
(Pas évident quand on est débutant sur Linux mais formateur:))
Super ! ça marche. il reste un problème sur Ubuntu quand j'arrête le système, le pc est très long à s'éteindre (le curseur clignote pendant ~ 2mn).
Il me restera à modifier l'ordre des démarrages ( je met W10 en premier ) en espérant ne pas faire de nouvelles bêtises .
Je continue à faire quelques test et passerais en résolu si tout va bien d'ici quelques jours.
Un grand merci pour votre  disponibilité et aide.

Re : réparation grub

Quel est l'intérêt de mettre windows sur la première ligne?
Si tu veux que windows boote par défaut, il suffit de dire que c'est la ligne N° 3 ( à vérifier en comptant les lignes) au lieu de la ligne N° 0. ( GRUB_DEFAULT="saved").

Nota.
J'ai vu que la réparation fut dure.

GRUB est encore absent. Veuillez réessayer.
