Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Oui, j'ai installé Refind depuis Windows (je n'y arrivais pas depuis ubuntu...) mais par contre, le menu proposé, c'est plutôt dans ce genre là :
https://www.blog-nouvelles-technologies … s-10-7.jpg

J'ai décrit plus en détail les différents menus dans mon message précédent.

En tous cas, ça ne ressemble pas à un refind normal...
Mon Refind serait mal installé ?

On dirait que oui... Du coup, j'ai refait la manip
https://doc.ubuntu-fr.org/refind#depuis_windows
et je me retrouve avec 2 boutons Refind qui m'envoient vers une réparation automatique...
Pourtant, au moment de l'installation via le Windows PowerShell, il me dit que tout va bien, opération réussies, etc... Comme j'avais vu un changement par rapport à d'habitude, je croyais que c'était bon...


Sinon, j'ai ouvert l'invite de commande Windows en tant qu'administrateur (FENÊTRE+R puis taper CMD et valider avec Ctrl+Alt+Shift) et là, ça me donne :

C:\Windows\system32>bcdedit /set {bootmgr} path \EFI\BOOT\BOOTX64.EFI/code]
L'opération a réussi.

C:\Windows\system32>

Je redémarre et là...

à nouveau la proposition "Windows 10 / Refind"

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Bonjour.

On va  certainement réussir très rapidement.

a) Je t'ai proposé de remplacer le fichier de boot de windows par celui du grub avec cette commande

bcdedit /set {bootmgr} path \EFI\BOOT\BOOTX64.EFI

On voit que cela ne fonctionne pas.

b) Tu as installé refind via windows, ce qui est totalement normal, c'est basé sur un meilleur principe.
   - Création d'une nouvelle entrée    avec le nom du fichier de boot.
   - Mettre cette entrée prioritaire.
L'avantage de cette solution est que si l'entrée ne fonctionne pas, l'entrée officielle est toujours présente sans avoir besoin de réparer.

     L'image d'écran que tu montres, indique clairement que le refind n'a pas mis en route mais que c'est windows qui managea.
   Tu pourras le vérifier en exécutant  ce qui est décrit dans cette discussion
https://doc.ubuntu-fr.org/refind#depuis_windows

C) Conclusion: Tu as aussi un windows bridé.   La solution est d'écraser le vrai fichier de boot de windows par le fichier de boot qu'on veut utiliser: Soit  refind, soit GRUBX64.

Le problème est qu'il faut aussi être  capable de proposer windows dans la structure de boot.
Je trouve que c'est plus facile à faire avec REFIND. De plus, il me semble plus moderne avec choix par la souris, voir le doigt,  et il sait détecter immédiatement les changements sans travail préparatoire.

Il faut donc que tu fasses ce qui est décrit au paragraphe 6.9 de refind.

Voici  les commandes

1)   Booter avec le support d'installation et choisir essayer avant d'installer. Ouvrir un terminal.
2)   Monter la partition de boot avec la commande

 sudo mount -v /dev/sdb2  /mnt

3)    Par prudence, sauver le fichier de boot de windows avec cette commande

sudo cp -v /mnt/efi/Microsoft/Boot/bootmgfw.efi /mnt/efi/Microsoft/Boot/bootmgfw$(date +"-%Y-%m-%d-%H-%M-%S").efi

NOTA, si le sauvetage ne se fait pas, donne le retour de la commande

sudo   ls -Rls /mnt

4) Ouvrir le fichier de paramétrage avec cette commande

 sudo nano /mnt/efi/refind/refind.conf

5) Y insérer les lignes suivantes:

menuentry "Windows 10" {
    icon \EFI\refind\icons\os_win.png
    loader \EFI\Microsoft\Boot\bkbootmgfw.efi
}

6)  Sauvegarder le fichier et quitter nano.
7)   Mettre la structure de boot de refind dans la structure de boot de windows avec cette commande:

 sudo cp -Rv /mnt/efi/refind/* /mnt/efi/Microsoft/Boot

8)  Mettre le fichier de boot de windows à l'endroit prévu par refind avec cette commande:

 sudo cp -v /mnt/efi/Microsoft/Boot/bootmgfw.efi /mnt/efi/Microsoft/Boot/bkbootmgfw.efi

9) Mettre le fichier de boot de refind à la place de celui de windows avec cette commande:

sudo cp -v /mnt/efi/Microsoft/Boot/refind_x64.efi /mnt/efi/Microsoft/Boot/bootmgfw.efi

10) Quitter le support d'installation et booter.

Lorsque Windows fera une grosse mise à jour, il se remettra prioritaire. Il faudra de nouveau rectifier en refaisant uniquement les deux dernières commandes.

# Whether to store rEFInd's rEFInd-specific variables in NVRAM (1, true,

# however, it increases wear on the motherboard's NVRAM, and if the EFI
# is buggy or the NVRAM is old and worn out, it may not work at all.
# Storing variables on disk is a viable alternative in such cases, or

--------------------------# if you want to minimize wear and tear on the NVRAM; however, it won't

#textonly
--------------------------
#
#textonly

# Set the EFI text mode to be used for textual displays. This option

# text mode; it uses whatever was in use when the program was launched.
# If you specify an invalid mode, rEFInd pauses during boot to inform
# you of valid modes.
# CAUTION: On VirtualBox, and perhaps on some real computers, specifying
# a text mode and uncommenting the "textonly" option while NOT specifying

# Set the screen's video resolution. Pass this option either:

# Note that not all resolutions are supported. On UEFI systems, passing
# an incorrect value results in a message being shown on the screen to
# that effect, along with a list of supported modes. On EFI 1.x systems
# (e.g., Macintoshes), setting an incorrect mode silently fails. On both
# types of systems, setting an incorrect resolution results in the default
# resolution being used. A resolution of 1024x768 usually works, but higher
# values often don't.

# directories. You might use this token to keep EFI/boot/bootx64.efi out
# of the menu if that's a duplicate of another boot loader or to exclude
# a directory that holds drivers or non-bootloader utilities provided by
# a hardware manufacturer. If a directory is listed both here and in

# Scan for Linux kernels that lack a ".efi" filename extension. This is
# useful for better integration with Linux distributions that provide
# kernels with EFI stub loaders but that don't give those kernels filenames
# that end in ".efi", particularly if the kernels are stored on a
# filesystem that the EFI can read. When set to "1", "true", or "on", this
# option causes all files in scanned directories with names that begin with
# "vmlinuz" or "bzImage" to be included as loaders, even if they lack ".efi"
# extensions. Passing this option a "0", "false", or "off" value causes
# kernels without ".efi" extensions to NOT be scanned.
# Default is "true" -- to scan for kernels without ".efi" extensions.

# Combine all Linux kernels in a given directory into a single entry.
# When so set, the kernel with the most recent time stamp will be launched
# by default, and its filename will appear in the entry's description.

# Comma-delimited list of strings to treat as if they were numbers for the
# purpose of kernel version number detection. These strings are matched on a
# first-found basis; that is, if you want to treat both "linux-lts" and
# "linux" as version strings, they MUST be specified as "linux-lts,linux",
# since if you specify it the other way, both vmlinuz-linux and
# vmlinuz-linux-lts will return with "linux" as the "version string," which
# is not what you'd want. Also, if the kernel or initrd file includes both a
# specified string and digits, the "version string" includes both. For
# instance, "vmlinuz-linux-4.8" would yield a version string of "linux-4.8".
# This option is intended for Arch and other distributions that don't include
# version numbers in their kernel filenames, but may provide other uniquely
# identifying strings for multiple kernels. If this feature causes problems
# (say, if your kernel filename includes "linux" but the initrd filename
# doesn't), be sure this is set to an empty string
# (extra_kernel_version_strings "") or comment out the option to disable it.
# Default is no extra version strings

# Set the default menu selection.  The available arguments match the
# keyboard accelerators available within rEFInd.  You may select the

#  - A digit between 1 and 9, in which case the Nth loader in the menu
#    will be the default. 
#  - A "+" symbol at the start of the string, which refers to the most
#    recently booted loader.
#  - Any substring that corresponds to a portion of the loader's title
#    (usually the OS's name, boot loader's path, or a volume or
#    filesystem title).
# You may also specify multiple selectors by separating them with commas
# and enclosing the list in quotes. (The "+" option is only meaningful in
# this context.)
# If you follow the selector(s) with two times, in 24-hour format, the
# default will apply only between those times. The times are in the
# motherboard's time standard, whether that's UTC or local time, so if
# you use UTC, you'll need to adjust this from local time manually.
# Times may span midnight as in "23:30 00:30", which applies to 11:30 PM

# Sample manual configuration stanzas. Each begins with the "menuentry"
# keyword followed by a name that's to appear in the menu (use quotes
# if you want the name to contain a space) and an open curly brace
# ("{"). Each entry ends with a close curly brace ("}"). Common
# keywords within each stanza include:
#
#  volume    - identifies the filesystem from which subsequent files
#              are loaded. You can specify the volume by filesystem
#              label, by partition label, or by partition GUID number
#              (but NOT yet by filesystem UUID number).
#  loader    - identifies the boot loader file
#  initrd    - Specifies an initial RAM disk file
#  icon      - specifies a custom boot loader icon
#  ostype    - OS type code to determine boot options available by
#              pressing Insert. Valid values are "MacOS", "Linux",
#              "Windows", and "XOM". Case-sensitive.
#  graphics  - set to "on" to enable graphics-mode boot (useful
#              mainly for MacOS) or "off" for text-mode boot.
#              Default is auto-detected from loader filename.
#  options   - sets options to be passed to the boot loader; use
#              quotes if more than one option should be passed or
#              if any options use characters that might be changed
#              by rEFInd parsing procedures (=, /, #, or tab).
#  disabled  - use alone or set to "yes" to disable this entry.
#
# Note that you can use either DOS/Windows/EFI-style backslashes (\)
# or Unix-style forward slashes (/) as directory separators. Either
# way, all file references are on the ESP from which rEFInd was

# or Unix-style forward slashes (/) as directory separators. Either
# way, all file references are on the ESP from which rEFInd was
# launched.
# Use of quotes around parameters causes them to be interpreted as
# one keyword, and for parsing of special characters (spaces, =, /,
# and #) to be disabled. This is useful mainly with the "options"
# keyword. Use of quotes around parameters that specify filenames is
# permissible, but you must then use backslashes instead of slashes,
# except when you must pass a forward slash to the loader, as when
# passing a root= option to a Linux kernel.

=================== 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 sdb5, using the following options:        sdb2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sdb2/efi/.../grub*.efi file!

If your computer reboots directly into Windows, try to change the boot order in your BIOS.
If your BIOS 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\...\grub*.efi


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

Je reboot et là...





rEFInd fonctionne !
Le menu s'affiche comme sur les photos !

par contre, il y a 2 icones refind et surtout 2 icones ubuntu qui ne fonctionnent pas :
ça et renvoient vers un écran noir :

GNU GRUB version 2.02
minimal BASH-like line editing is supported. For the fist word, TAB lists possible command completions. Answer else TAB lists possible device or file completions.

grub> -

ça avance, mais je trouve que c'est un peu long et compliqué...

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Bonjour
C'est déjà une bonne chose que refind commence a ressembler à quelque chose que je connais

Pour les icones qui ne fonctionnent pas,   si tu regardes sous l'icone, tu devrais voir  des caraceteres qui représentent le répertoire et le fichier de boot.
Si tu peux donner le contenu, cela serait bien

pour ubuntu, j'ai vu ce fichier de boot

========================= sdb2/EFI/ubuntu/grub.cfg: ===========================
--------------------------------------------------------------------------------
search.fs_uuid 0dee4fb2-8586-4f16-8a3a-6c5af429f468 root hd1,gpt5 
set prefix=($root)'/boot/grub'

Mais cette partition a changé de UUID

/dev/sdb5: UUID="0e13e9e9-298b-4cdb-a0a8-ad18f31d915b" TYPE="ext4" PARTUUID="a35817e1-44c7-49ed-8bc4-1ad8c0ff8909"

En regardant bien cette partition,   la structure /boot/grub n'est pas présente.
La cause très probable est que j'e t'ai fais installé le package GRUB-EFI   alors que c'est probablement  GRUB-EFI-AMD
J'ai corrigé.
Si tu pouvais rejouer  ces deux séquences https://forum.ubuntu-fr.org/viewtopic.p … #p22165525

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

voila ce qui est écrit sous les 2 icônes ubuntu defectueuses :
Boot EFI\ubuntu\grubx64.efi from EFI system partion
Boot boot\vmlinuz-5.0.0-3-generic from 15 Gib ext4 volume

je m'occupe à présent des 2 séquences...

voila, c'est fait, le ping a marché etc....et un nouveau 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 sdb5, using the following options:        sdb2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sdb2/efi/.../grub*.efi file!

If your computer reboots directly into Windows, try to change the boot order in your BIOS.
If your BIOS 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\...\grub*.efi


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

et je rédémarre et là...

le premier ne fonctionne toujours pas, mais le second, commence par un écran noir ressemblant au précédent, puis les lignes de code se mettent à défiler...

ALELUIA !!!!! big_smile lol

le bionic beaver apparaît enfin !!!!!

je fais les mises à jour.
ensuite, je redémarre et constate que le rEFInd a toujours ses icônes surnuméraires qu'il ne s'est pas nettoyé tout seul...
et il y a le rEFInd defectueux installé via windows qui est toujours là au démarrage de Windows10...

Est-ce qu'il y a moyen de faire le ménage de ce côté ?

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Bonjour.
Avant de nettoyer, un petit point va s'imposer car je suis un peu surpris   du résultat du boot-info.
D"abord, le contenu de la NVRAM

=================== efibootmgr -v

Boot2001* EFI USB Device	RC

On voit que le boot actuel a eu lieu sur le N°1     qui est windows installé dans cette partition 14900409-1bbb-456e-b34d-10ede1ca9ed4
Qui est SDB2

/dev/sdb2: UUID="EC77-0FB8" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="14900409-1bbb-456e-b34d-10ede1ca9ed4"

Mais d'après le boot-info, Il n'y a pas de fichiers dans SDB2

sdb2: __________________________________________________________________________

    Boot sector info:  No errors found in the Boot Parameter Block.

Alors, je me demande comment cela boote réellement maintenant car  dans ton boot-info de 17 heures 48, Tout le semblait normal

Je ne sais pas ce qui a pu se passer, Je  peux   admettre que la nouvelle installation du grub-EFI-AMD  a supprimé ubuntu,  Mais cela serait grave, si windows et refind avaient été supprimés, D'ailleurs, tu ne pourrais plus booter. Ce qui n'est pas le cas.

En recherchant un peu plus, j'ai fait cette découverte

Presence of EFI/Boot file d   en trop etected: /mnt/mnt/EFI/Boot/refind_x64.efi

A mon avis, il y a  un /mnt en trop dans les noms de fichiers.
    Je suis incapable de savoir    si c'est la réalité ou si boot-repair nous joue un tour.

Cela serait bien que tu refasses un boot-info depuis la session installée
Si toujours cette ambiguité, on pourra aller directement voir en ligne de commande.
Je note déjà que c'est bien SDB2

=============================== sdb5/etc/fstab: ================================
....
UUID=0e13e9e9-298b-4cdb-a0a8-ad18f31d915b /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sdb2 during installation
UUID=EC77-0FB8  /boot/efi       vfat    umask=0077      0       1

Pour la suppression du refind windows, il y a trois possibilités
   1)    Supprimer l'entrée que tu as créée en suivant la procédure d'installation windows Au paragraphe 2.2  En théorie, cela devrait se réparer automatiquement.
    De mémoire c'est la commande "bcdedit /delete   ........"
   2)    Dire que l'entrée courrante boote avec  le fichier de boot de windows et pas avec refind  (ou le grub)   
   3)   Changer l'ordre de boot, pour remettre l'entrée initiale en mode prioritaire.
Pour le moment, je te propose de faire seulement un état des lieux avec windows  en lançant windows power shell en mode mode administratif et faire ces deux commandes

bcdedit >BCD.txt
notepad BCD.txt

et poster le contenu qui s'affichera
Voir une quatiéme possibilité avec des commandes efibootmgr

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

=================== 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:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda2/efi/.../grub*.efi !

Si votre ordinateur redémarre directement sur Windows, essayez de changer l'ordre de démarrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut de l'amorceur Windows.
Par exemple, vous pouvez démarrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateur :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi


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

Il y aurait donc eu un petit dysfonctionnement dans le boot-info précédant

Tu peux déjà supprimer quelques entrées de boot inutiles

sudo efibootmgr  -B -b 6
sudo efibootmgr  -B -b 5
sudo efibootmgr  -B -b 4
sudo efibootmgr  -B -b 3
sudo efibootmgr  -B -b 0

Ainsi que ce fichier et ce répertoire

sudo rm -v /boot/efi/EFI/EFI/ubuntu/grubx64.efi 
sudo rmdir -v /boot/efi/EFI/EFI/ubuntu
sudo rmdi  -v /boot/efi/EFI/EFI

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Euh... ça freeze quand je tente la première ligne de commande "sudo efibootmgr  -B -b 6"
C'est normal ?

et pareil pour la seconde : "sudo efibootmgr  -B -b 5"

Est-ce la peine de tenter les autres ?

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Pour les commandes EFIBOOTMGR, c'est fichu. (Sauf à demander une réinitialisation du bios EFI. Ce qui fait toujours peur.)
Tu pourras toujours faire les commandes de suppression du fichier
Pour BCDEDIT, tu as le contenu suivant

Gestionnaire de démarrage Windows
---------------------------------
identificateur          {bootmgr}
device                  partition=\Device\HarddiskVolume2
path                    \EFI\BOOT\BOOTX64.EFI/code]
description             Windows Boot Manager

Je ne sais pas dire s'il est bon ou pas,,,    Il faudrait que je reboote en windows pour comparer.

Tu peux  supprimer les deux entrées refind 

bcdedit    /delete    '{10cb7215-f393-11e9-88b2-a86daa358fad}'
bcdedit   /delete   '{daaa503b-eaa7-11e9-8b8b-b12c1ce5a91d}'

Histoire de savoir si le grub signé ne va pas se réinstaller automatiquement, il serait bon que tu refasses les commandes

sudo apt update
sudo apt upgrade

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Bonjour
Donc pas de réinstallation de ubuntu, Tu peux purger avec cette commande qui'il faut faire régulièrement surtout si de nouveaux noyaux arrivent.

sudo apt autoremove --purge

Pour la récupération du contenu, j'avais oublié la redirection. C'était donc

bcdedit >BCD.txt
notepad BCD.txt

Pour la suppresion des deux entrées, j'avais oublié les quotes. C'est donc

bcdedit    /delete    '{10cb7215-f393-11e9-88b2-a86daa358fad}'
bcdedit   /delete     '{daaa503b-eaa7-11e9-8b8b-b12c1ce5a91d}'

Pour le gestionnaire de démarrage de windows,  chez moi ,  il y a

identificateur          {bootmgr}
device                  partition=\Device\HarddiskVolume2
path                    \EFI\Microsoft\Boot\bootmgfw.efi
description             Windows Boot Manage

Cela ne me surprend pas.....  Je te propose donc cette commande

bcdedit /set {bootmgr} path  \EFI\Microsoft\Boot\bootmgfw.efi

Bonsoir
Pour le premier, erreur de codif

 bcdedit /set   '{bootmgr}'    path  \EFI\Microsoft\Boot\bootmgfw.efi

Pour ubuntu, tu attends un petit quart d'heure  qu'il ait terminé son travail en tâche de fond.

=================== 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:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda2/efi/.../grub*.efi !

Si votre ordinateur redémarre directement sur Windows, essayez de changer l'ordre de démarrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut de l'amorceur Windows.
Par exemple, vous pouvez démarrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateur :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi


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

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Comme, à priori, on n'utilisera pas cette façon de booter tant que refind   sera utilisé, on pourrait supprimer  le fichier d'entrée. Mais je te propose de faire une réparation.
- Le fichier grub ne me semble pas au bon niveau.   On va l'y remettre avec cette commande

sudo    mv  -v  /boot/efi/EFI/EFI/ubuntu/grubx64.efi    /boot/efi/EFI/ubuntu/grubx64.efi

- La première ligne du fichier de paramétrage  /boot/efi/EFI/ubuntu/grub.cfg contient une référence qui n'existe pas. Cette ligne doit devenir
search.fs_uuid 0e13e9e9-298b-4cdb-a0a8-ad18f31d915b root hd0,gpt5

RMI973 a écrit :

* Boot boo\vmlinuz-5.0.0-32-generic from 15 GiB ext4 volume (qui fait défiler les lignes de code au démarrage et à la fermeture d'ubuntu)
mais c'est pas gênant

En standard, le fichier de paramétrage du grub contient une option splash permettant de ne pas lister les actions qui se passent
C'est certainement un bon choix lorsque tout fonctionne. C'est probablement un mauvais choix lorsqu'io y a des ennuis. Je pense que le fauit de masquer doitr faire qagner   une seconde  au temps de démarrage.
D'après ta description, le fichier de paramétrage  (facultatif) de refind ne  contient pas cette option splash. Il est vrai que l'installation n'a pas été simple.

Voici comment faire pour masquer les traces de démarrage.
- Vérifier que le fichier de configuration de refind est bien présent avec la commande suivante

cat /boot/refind_linux.conf

-S'il n'existe pas
       Il faudra le créer avec cette commande

      sudo touch  /boot/refind_linux.conf

      Puis lui mettre les deux lignes suivantes

"Boot with standard options"   "root=UUID=0e13e9e9-298b-4cdb-a0a8-ad18f31d915b ro quiet splash vt.handoff=7"
"Boot with recovery options"   "recovery nomodeset ro root=UUID=0e13e9e9-298b-4cdb-a0a8-ad18f31d915b"

-S'il existe, tu te contentes d'ajouter les mots manquants dans la première ligne  ( quiet splash vt.handoff=7 )

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

voila ce que ça a donné :

bota@bota-Aspire-ES1-732:~$ sudo    mv  -v  /boot/efi/EFI/EFI/ubuntu/grubx64.efi    /boot/efi/EFI/ubuntu/grubx64.efi
[sudo] Mot de passe de bota : 
renamed '/boot/efi/EFI/EFI/ubuntu/grubx64.efi' -> '/boot/efi/EFI/ubuntu/grubx64.efi'
bota@bota-Aspire-ES1-732:~$ cat /boot/refind_linux.conf
cat: /boot/refind_linux.conf: Aucun fichier ou dossier de ce type
bota@bota-Aspire-ES1-732:~$       sudo touch  /boot/refind_linux.conf
bota@bota-Aspire-ES1-732:~$ "Boot with standard options"   "root=UUID=0e13e9e9-298b-4cdb-a0a8-ad18f31d915b ro quiet splash vt.handoff=7"
Boot with standard options : commande introuvable
bota@bota-Aspire-ES1-732:~$ "Boot with recovery options"   "recovery nomodeset ro root=UUID=0e13e9e9-298b-4cdb-a0a8-ad18f31d915b"
Boot with recovery options : commande introuvable

le résultat est étonnant. A présent le premier boot ubuntu (qui ne fonctionnait pas) fonctionne en passant par l'invite de commande "classique" d'ubuntu sur fond violet, et le second qui fonctionnait, désormais plante après avoir fait défiler un flux de lignes de code finissant par ça :

[...]
BusyBox v1.27.2 (ubuntu 1:1.27.2ubuntu3.2) built-in shell 'ash)
Enter 'help' for a list of built-in commands.

Re : install dual boot ubuntu/win10 sur Aspire ES17 qui bloque à GRUB2

Normal
Tu as créé le fichier de configuration /boot/refind_linux.conf
et tu n'as pas mis les deux lignes dedans. Tu t'es contenté de les passer comme des commandes.
Donc ouvrirle fichier créé avec cette commande

gedit admin:///boot/refind_linux.conf

puis un copier/coller des deux lignes suivantes

"Boot with standard options"   "root=UUID=0e13e9e9-298b-4cdb-a0a8-ad18f31d915b ro quiet splash vt.handoff=7"
"Boot with recovery options"   "recovery nomodeset ro root=UUID=0e13e9e9-298b-4cdb-a0a8-ad18f31d915b

dans la zone de saisie   et sauver avant de quitter.

Je ne peux pas modifier le fichier refind_linux.conf qui est en lecture seule. Il me dit que je n'en suis pas propriétaire...
