Mon installation n'apparaît même pas dans le bios !!!

Help !!! J'ai une présentation demain matin et je n'ai que cet ordi !!

Bonjour à tous !

Ce matin, mon ordi a commencé à avoir des soucis. Comme mon /home est sur une autre partition, je me suis lancé dans la réalisation d'une clef pour réinstaller Ubuntu 18 LTS (à la place de la 16).

Dans la table de partition de l'installation, j'avais fait:

hd1:
1. partition /home 500Go.
hs1:
1. partition / 24Go
2. partition swap 1Go

Sauf que l'installation plantait au moment d'installer grub. J'ai cherché, et j'ai trouvé qu'il fallait rajouter une partition EFI. J'ai rajouté une partition de 200Mo EFI entre hs1 1. et hs1 2. L'installation se poursuivait bien et j'arrivais au terme.

Seulement, au démarage, je tombais en grub rescue. J'ai cherché, et j'ai vu que j'avais dans mon /boot/grub un dossier x86-64-efi qui semblait être associé à un grub efi, tandis que la commande insmode essayait par tous les moyens de trouver un dossier i386-pc, qui n'existait pas.

Finalement, j'ai réinstallé en me trompant à un moment, j'ai activé par mégarde le secure mode dans le bios, puis après une autre installation, je l'ai enlevé, et maintenant, plus rien n'apparaît sur le bios et je démarre dessus.

Le boot info est ici.

Désolé pour la question classique et pour le fouilli, mais je suis un peu paniqué, j'ai une présentation demain matin. J'ai le pdf sur une clef, mais j'ai encore une ou deux choses à modifier sur un logiciel spécialisé :s

Re : Mon installation n'apparaît même pas dans le bios !!!

En tous cas, ton DD de 500go comme celui de 22go, ta sd semble-t-il, ont une table de partition ms-dos, donc pour installe legacy.

Comprends pas que tu ais foutu une partoche efi sur ta sd et surtout passer le bios en mode efi.

Peux-tu obtenir quelque chose via le boot-menu du bios ?

Sinon, vu le délai, t'as plus qu'à bosser avec ton support live, si toutefois ton soft le permet.

Re : Mon installation n'apparaît même pas dans le bios !!!

Ok, alos je reprend:

1. ma table de partition est de type ms-dos ? Eux, certainement .. Et alors ? Quel est le soucis avec legacy instal ?
2. Le boot menu du bios n'affiche rien.
3. C'est du LaTeX. Je peux toujours compiler avec le sharelatex de mon équipe, mais comme je suis disponible pour tenter toute action, ça dépendra de la réactivité des réponses. En attendant, je répète en modifiant les fichiers.

En gras, c'est là que t'as rien compris, le legacy c'est pas du efi, ton soucis, c'est d'etre passer en efi (partoche, plus bios) alors que rien ne s'y pretait ! En fait, c'était pas nécessaire.

M'est avis que tes problemes systemes viennent de ta sd, mais le dd de ton /home n'est pas rempli

/dev/sda1      ext4      459G   89G  347G  21% /mnt/boot-sav/sda1

J'ai une idée de soluce mais ce sera chaud les marrons ! Et à la condition que tu puisses passer ton bios en mode legacy, pour ton support de boot comme pour le hdd.

Elle implique de sauvegarder ton /hom.

Car il y faudra libérer de l'espace non-alloué pour y mettre une racine (au mons 30go) plus une partition swap au moins égale à ta ram (6go apparemment.) Bref, en tout 40 go. Cela se fera avec gparted avec ton support live.

=================== 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:        sdb6/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file  restore-efi-backups


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sdb6/efi/.../grub*.efi file!


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