Triple boot Efi Win7/Win10 et UBUNTU...

studywes · Le 11/10/2018, à 14:58

Salut tout le monde,

Dans le cadre de projets de custom firmware Android, j'ai besoin de Linux et comme j'ai une partoche dispo dans mon PC, je me demandai s'il était aisé de faire un multiboot? Je pose cette question surtout en liaison avec mon Bios EFI actuel, car j'ai installé Ubuntu en multiboot il y a quelques années mais c'était avec un PC avec BIOS classique

Merci de votre aide

Y a pas de raison du contraire.

Avec ton support ubuntu fais un boot-info (voir doc) pour voir comment est fait le dual-boot w7-w10.

Bonjour
Normalement il est très facile d'installer un dual boot.https://doc.ubuntu-fr.org/uefi.
Le grub qui dirige l'opération va te proposer la liste de tous les O.S. présents. La particularité en EFI c'est que tous les windows sont vus comme un seul OS.
Lorsque tu choisis de booter windows, Le gestionnaire de boot de windows est alors activé. C'est lui qui te proposera la liste de tous tes windows.
Cependant, certains ordinateurs EFI ( les HP) bootent systématiquement sur windows, Il faut alors appuyer sur une touche pour booter sur le grub.

Salut,

Merci pour ces precisions, pour info j'ai un PC portable Asus R900V et des partitions GPT! Je penses que ça à son importance également!
EN résumé,
-> je vérifie les pré-requis: désactiver le QuickBoot (parfois appelé FastBoot) / Intel Smart Response Technology (SRT) / désactivez le démarrage rapide ("Fast Startup" Off).
-> j'installe ubuntu normalement en bootant ma clef USB créer avec Rufus en mode EFI
-> Je laisse Grub fair le job au démarrage
On doit être bon normalement

Si tu ne veux pas fournir un rapport boot-info, toi seul peux dire.

Additional repair would be performed:  repair-filesystems  fix-windows-boot


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

Déjà t'as booté ton support en efi, donc ton bios est ok pour une installe efi.

Par contre tu as deux disques :
sda où se trouverait w7
sdb avec w10 en mode efi et ce serait sur ce disque que tu devrais faire ton installe buntu en efi (si il y a de l'espace non-alloué).

Salut,

Tout d'abord merci de ton et du temps que tu consacre à l'entraide . Sinon pour l'EFI je suis en phase, concernant les Hdd, j'ai un ssd avec Win 7 et Win 10 sur des partitions différentes et un Hdd mecanique pour le stockage de donnée!J'ai réduit l'espace alloué de Win7 pour créer une partition Ubuntu. Est ce que ca peut le faire comma ca?
Voila ce que je souhaitais faire:

merci

Ça colle et c'est le bon disque pour de l'uefi, sinon que ta partition G pour buntu doit etre non-formaté !

Avec le gestionnaire de disque windows, tu supprimes la partoche G qui deviendra de l'espace non-alloué.

En pré-requis avant de lancer l'installe, sous win tu choisis "redémarrer", cela stop son hibernation qui autrement peut bloquer l'accès à la partoche EFI.

Avec l'installateur, j'ai pas l'expérience quand y a plusieurs disques, veilles à choisir le bon (la différence en go est indicative) et normalement il te proposera d'installer à cotés de windows.
