Pas de grub au démarrage

LeRouge · Le 26/04/2017, à 15:06

Bonjour,

Je viens de faire l'acquisition d'un PC portable ACER Aspire avec Windows 10 installé dessus.

Je me suis donc empressé d'installer Kubuntu 17.04. L'installation s'est bien passée mais par contre impossible d'avoir un Grub, même en faisant un boot-repair..
J'ai réussi à démarrer une seule fois Kubuntu en passant par le boot Menu (touche F12) qui me laissait le choix entre Windows 10 et Toshiba quelque chose... et je suis extrêmement imprécis car je n'ai eu ce choix qu'une seule fois, à présent seul windows 10 s'affiche...

J'hésite donc à désinstaller kubuntu via une live USB pour recommencer l'installation à zéro au cas où j'ai oublié quelque chose au milieu. Mais das*ns le doute, quelqu'un a-t-il une idée ?

Merci à vous !

Un boot-info depuis ta clef en live serait bien (voir dans la doc).

Bonsoir

Vérifie que ton lien est correct, et si tu constates qu'il ne l'est pas, recommence.

Bonjour

Logiquement ca devrait mieux aller avec celui ci http://paste.ubuntu.com/24466134/

Bonjour,

Je reviens pour que mon message remonte.
Quelqu'un peut-il me filer un coup de main ?

=================== Suggested repair
The default repair of the Boot-Repair utility would not act on the MBR.
Additional repair would be performed:  repair-filesystems  fix-windows-boot


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

Déja un problème

sda5: __________________________________________________________________________

    File system:       ext4
    Boot sector type:  -
    Boot sector info: 
    Mounting failed:   mount: unknown filesystem type ''
mount: wrong fs type, bad option, bad superblock on /dev/sda5,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

On voit ici l'absence de gru en sda5

sda5	: sda,	not-sepboot,	no-grubenv	nogrub,	no-docgrub,	no-update-grub,	32,	no-boot,	is-os,

à croire que ton disque a un pète en sda5, ou alors selon la façon dont tu as liberé les 520go pour cette partition, qu'as-tu fais?
