[Résolu] plantage après installation Acer Inspire One 11

bonjour et merci d'avance de lire ma question.
Je viens d'installer sur un Acer Inspire One 11 (AO1-132-C3FQ) Ubuntu 16.04.1 LTS, après un essai en Live sans aucun problème.
Après Grub, écran noir tout de suite. En mode recovery, deux lignes seulement s'affichent :

Chargement de Linux 4.4.0-31-generic...
Chargement du disque mémoire initial...

puis le curseur reste bloqué. Aucun moyen d'ouvrir une console ou quoi que soit d'autre.
J'avais fait ma clé avec l'accessoire de Linux Mint.
Le rapport Boot-info, que j'ai fait à partir du Live-USB, est là : http://paste2.org/78jLUhwn.

Même si ça fait un paquet d'années que je fais des installations, on ne peut pas dire que mon niveau théorique soit très élevé... Mais là il y a un enjeu terrible, c'est toute ma campagne de conversion à Linux auprès de mes collègues-copains qui est remise en cause (l'Acer en question n'est pas à moi mais à un copain qui avait tenté une première fois l'installation avec Mint 18.1 Xfce).
Merci de vos conseils !

Bonjour pierrefmc et bienvenue sur ce forum smile

Effectivement, l'enjeu est de taille tongue.

À première vue, Ubuntu est bien installé sur ta machine (sur sda1): 

"blkid" output: ________________________________________________________________

Device           UUID                                   TYPE       LABEL

/dev/loop0                                              squashfs   
/dev/mmcblk0                                                       
/dev/mmcblk0p1   14375572-cc68-47a4-a596-90f86bdb89ef   ext4       
/dev/mmcblk0p5   9c09b5c5-e39c-483e-9c61-c051945b77be   swap       
/dev/sda1        2016-07-19-21-27-51-00                 iso9660    Ubuntu 16.04.1 LTS amd64
/dev/sda2 0F7B-9366 vfat

Mais il n'est pas accessible parce qu'il manque le boot-loader;

=> No known boot loader is installed in the MBR of /dev/sda.

Je commencerais par réparer le secteur de boot:
https://doc.ubuntu-fr.org/tutoriel/comm … aurer_grub
Comme le suggère le rapport Boot-info: 

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of mmcblk0p1 into the MBRs of all disks (except USB without OS).
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on mmcblk0 (31.3GB) disk!

Si cela ne suffit pas tu pourrais recommencer l'install en suivant ce tuto qui, faute de mieux, m'a l'air adapté à la situation. Garde la version 16.04.1.

Si ça ne marche toujours pas, cherche de l'aide dans ta région.

Désolé de ne pas pouvoir t'en dire plus. Je n'ai encore aucune expérience des install en EFI.
Mais un membre plus câlé se joindra peut-être à cette discussion.

Re : [Résolu] plantage après installation Acer Inspire One 11

bonjour et merci pour vos conseils. J'avais un peu pris le large et pas regardé les réponses, je n'ai donc suivi les conseils de hibou7 qu'avant hier. Sans succès, même si j'arrivais au menu de Grub (ce qui n'était pas le cas avant). Après, écran noir, et en recovery, plantage immédiat.
J'avais repéré que Parinux organisait une "journée du libre" ce samedi 25... et bingo !
Un des bénévoles, Manu, a trouvé ici la solution.
Le problème, c'est que me basant sur mes expériences antérieures, j'avais configuré le BIOS en legacy au lieu d'UEFI. En rétablissant le mode UEFI, j'ai pu ré-installer et tout fonctionne ! Après l'installation, il faut modifier le BIOS comme indiqué dans le lien donné ci-dessus.
Bon, après une quinzaine d'année à compter surtout sur les conseils en ligne et les forums, j'ai bien profité de ma première vraie rencontre avec la communauté. Merci donc à ses bénévoles !

Oups; je me rends compte que dans sa réponse, hibou7 me mettait déjà sur la piste finalement suivie ! J'avais sauté la ligne et après avoir échoué sur les premiers conseils, j'étais passé directement à "l'aide dans [ma] région".

Merci du retour, je n'aurais même pas remarqué que mes recherches ont été utiles.
Mais comme tu l'as écrit au #3, rencontrer des GNU/linuxiens en chair et en os fait toujours du bien et donne de nouvelles idées. C'est comme ça pour moi aussi.

J'ai ajouté ton modèle à la liste des portables Acer ici, le troisième de la liste.
Veux-tu bien contrôler si ce que j'ai écrit est correct (par exemple, version installée).
Merci

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of mmcblk0p1 into the MBRs of all disks (except USB without OS).
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on mmcblk0 (31.3GB) disk!


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