Re : Installation Kubuntu en Dual Boot avec W10

Salut,
J'utilise depuis des années et sur tous mes PC un /home séparé. Je n'ai jamais eu cette panne qui est probablement liée à une faiblesse du disque. Avoir une seule partition n'empêcherait pas le disque de flancher.

Moi aussi j'ai jamais eu cette panne, bref, c'est sans doute possible.

Re : Installation Kubuntu en Dual Boot avec W10

J'ai tout réinstallé, W10 et Xubuntu, c'est cool, merci bcp
dernière petite question, évidment j'ai oublié de dire à Xubuntu qu'il devait monter la partition de windows à chaque démarrage.Est-ce que ya moyen de changer ça pour qu'il monte la partition Windows à chaque démarrage? Merci

Re : Installation Kubuntu en Dual Boot avec W10

Bonjour,
Puisque tu as tout réinstallé, ce serait utile de voir ce que ça donne. Aussi, je te prie de faire un Boot-info depuis une session de ton Xubuntu installé, puis de coller l'URL de ce Boot-info dans ta réponse.

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
sda5,
using the following options:        sda3/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file  restore-efi-backups  

Confirmation request before suggested repair: __________________________________

The boot of your PC is in Secure mode. You may want to retry after changing it to non-Secure mode.
Are you sure you want to continue anyway?

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.2 LTS CurrentSession entry (sda3/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)

La partie finale du Boot-info est un peu chargée (sda5/etc/grub.d/32_linux_zfs ; sda5/etc/grub.d/33_linux_xen ; sda5/etc/grub.d/36_uefi-firmware ). Je pense que c'est dû à ton utilisation de Grub Customizer qui doit perturber Boot-info.

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
sda5,
using the following options:        sda3/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file  restore-efi-backups  

Confirmation request before suggested repair: __________________________________

The boot of your PC is in Secure mode. You may want to retry after changing it to non-Secure mode.
Are you sure you want to continue anyway?

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.2 LTS CurrentSession entry (sda3/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)

La partie finale du Boot-info est un peu chargée (sda5/etc/grub.d/32_linux_zfs ; sda5/etc/grub.d/33_linux_xen ; sda5/etc/grub.d/36_uefi-firmware ). Je pense que c'est dû à ton utilisation de Grub Customizer qui doit perturber Boot-info.

Oui c'est ça j'ai mis Grub Customize pour avoir windows en premier lors du boot, la personne voulait avoir W10 en démarrage par défaut.
Ca peut poser des soucis ce Grub un peu broullion!

Salut,

Tu avais des solutions moins massives, soit en modifiant le fichier GRUB ou en renommant 30_os-prober. Mais bon, tant que ça fonctionne.

Moi je déconseille Grub Customizer mais il y a des utilisateurs satisfaits de cette daube.

Je veux bien m'en passer mais faut me dire comment on change l'ordre du Boot dans le Grub!

Re : Installation Kubuntu en Dual Boot avec W10

Bonjour
Par défaut, le grub est positionné  pour lancer  la première ligne appelée ligne 0
Il faut donc que tu bootes une fois normalement pour voir dans quelle position de ligne windows est affiché.
Par exemple, si c'est la 3eme ligne, on dit que c'est la ligne n°2
On ouvre donc le fichier /etc/default/grub à la recherche de la ligne GRUB_DEFAULT=0
On remplace 0 par 2 et on fait prendre en charge

sudo update-grub

Donc il faut d'abord que tu enlèves le grub-customizer  puis que tu fasses un boot  pour voir  la position de la ligne. Bien que cela puisse se trouver en regardant le contenu du fichier /boot/grub/grub.cfg

"gedit admin:///etc/fstab" est proscrit,  utilisez "pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY xdg-open /etc/fstab" Voir  https://doc.ubuntu-fr.org/gedit
