Emmabuntus

Bonjour,

Normalement grub s'installe sur l'en-tête de ton disque dur à la fin de l'installation. Je t'invite donc à reprendre ton installation jusqu'au bout, car manifestement, quelque chose ne s'est pas passé comme prévu. Autrement, tu peux essayer d'utiliser boot-repair qui sert précisément à réinstaller grub en cas de soucis au démarrage.

Bonne chance

Bonjour,

Je reprends tes derniers messages (merci au passage de soigner l'orthographe et de ne pas utiliser d'abréviations):

C'est rescue et non recue, vous l'avez bien compris

Ce n'est pas le message d'erreur exact (qui est ce que je te demande).

J'ai installé un autre disque oú le PC s'est deroulé bien la première fois et ça ne marche pas, tjours c'est le démarrage de syslinux de Alvin.

Je n'ai pas compris. Qu'est ce que c'est que ces histoires de syslinux et d'Alvin?

J'ai sorti le disque du PC qui marche, je l'ai mis sur le PC qui ne marchait pas et bien il marche.

Qu'entends-tu par il marche ? Tu arrives à démarrer sur emmabuntus ?

J'ai essayé bcp de Distributions oú le Grub est de syslinux et ça ne démarre pas

Je ne vois pas de quoi tu parles. Il n'y a pas 40 grub, ou plutôt, comme te l'a dit Patrick Emmaubuntus, tu as une version de grub selon que tu utilises un linux 64 bits (amd64) ou 32 bits (i386). Ensuite, il t'a également indiqué à juste titre que si ta carte mère avait un BIOS UEFI, il fallait en plus installer le paquet approprié (en particulier si le secure boot est activé dans le BIOS). Les distributions linux modernes prennent correctement ce genre de situations Plus de détails ici. Typiquement, voici les paquets grub que ton installeur est supposé déployé pour une machine 64 bits sur une machine avec UEFI :

(mando@silk) (~) $ dpkg -l | awk '/grub/ {print $2}'
grub-common
grub-efi-amd64
grub-efi-amd64-bin
grub-efi-amd64-signed
grub2-common

Enfin pour revenir à

boot-repair

, celui-ci génère un rapport et il serait bien de nous le partager. Cela nous permettrait de voir ton partitionnement, si tu es dans le cas UEFI ou pas, et enfin voir ce que

boot-repair

a fait.

Bonne chance

Bonjour,

Est-ce que ton linux démarre désormais correctement ?

Si on regarde les infos de

boot-repair

:

/dev/sda1 * 2,048 35,954,687 35,952,640 83 Linux
/dev/sda2 35,956,734 66,054,143 30,097,410 5 Extended
/dev/sda5 35,956,736 44,441,599 8,484,864 83 Linux
/dev/sda6 44,443,648 49,682,431 5,238,784 82 Linux swap / Solaris
/dev/sda7 49,684,480 50,356,223 671,744 83 Linux
/dev/sda8 50,358,272 66,054,143 15,695,872 83 Linux

... il n'y a pas de partition EFI. Ce n'est pas grave mais ça signifie que ton linux ne peut pas être démarré si le secure boot est activé dans le BIOS. Le secure boot est une fonctionnalité qui a été introduite pour renforcer la sécurité, mais elle n'a rien d'obligatoire. La seule chose à savoir c'est que si tu as installé disons windows en mode secure boot, alors il faut installer linux de la même façon (car tu ne peux pas démarrer un système ainsi installé en mode legacy).

Vu ton partitionnement, tu ne sembles avoir que windows (et pas de partition EFI) donc il faut t'assurer dans ton BIOS, dans les options de boot, que tu es bien en mode legacy, sans quoi ton BIOS refusera d'amorcer ton linux.

Si on regarde un peu plus loin :

=================== UEFI/Legacy mode:
This live-session is not EFI-compatible.
SecureBoot maybe enabled.

... donc on ne sait pas si l'option secure boot ou est activée dans ton BIOS ou pas.

Bonne chance

J'ai sortie le disque du PC qui marche, je l'ai mit sur le PC qui ne marchait pas et bien il marche.

J'ai installé un autre disque oú le PC s'est deroulé bien la première fois et ça ne marche pas, tjours c'est le démarrage de syslinux de Alvin.
