Default Boot Device Missing redémarrage

Bonjour à tous,
Je suis nouveaux sur le forum et je viens vous voir car j'ai un problème au redémarrage de mon ordi.
J'ai installer Ubuntu 18.05 lts il y a environs 1 mois et tout ce passez bien.
Mais tout à l'heure mon ordi commencer à faire beaucoup de bruit, j'ai donc voulu le redémarrer mais maintenant impossible de le redémarrer.
Il m'affiche "default Boot Device missing or boot failed"
J'ai essayer les solution que ai trouver sur les forum mais rien ne marche.
J'ai d'abord essayer dans le bios de mettre boot mode en 'legacy support' mais cela m'affiche rapidement un message et redémarre en boucle idem en mode recovery.
J'ai peut être une piste mais je n'en suis pas sur, plutot j'ai installer kali Linux sur VirtualBox et lors de l'installation je devais choisir si je devais installer un grub et j'ai mis oui peut être est-ce lié ?
Parcontre je peut démarrer en live USB et l'orsque je vais dans Disks en mode live je vois une partition :
Size : 1.0 TB
Assessment : disk is OK
Device : /dev/sda2
Partition Type : Linux Filesystem
J'imagine donc que ce n'est pas mon disque dur qui est mort ?

Je possède un Lenovo légion y520.
Merci à ceux qui m'aideront et dites moi si je doit vous donner d'autre information.

Ps: Je ne suis pas sur d'être dans la bonne section mais elle me sembler la mieux adapter.

Bonjour,
Fais un Boot-info depuis une session live et donne l'URL de ce Boot-info dans ta réponse.

Re : Default Boot Device Missing redémarrage

Mon live USB est sous kali Linux on ne peut pas faire boot-info dessus ?
Je vais télécharger Ubuntu sur une clé pour le lancer en live

(debug) reinstall grub2 place-in-MBR no-BIOS_boot (sda2)


=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub2 of sda2 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== Blockers in case of suggested repair
GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again.


=================== Advice in case of suggested repair
The boot of your PC is in EFI mode, but no EFI partition was detected. You may want to retry after creating a EFI partition (FAT32, 100MB~250MB, start of the disk, boot flag).
Do you want to continue?


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

Extrait de la partie "sda2/etc/fstab" du Boot-info :

# /boot/efi was on /dev/sda1 during installation
UUID=09CC-B4F2  /boot/efi       vfat    umask=0077      0       1

La partition sda1 dont l'UUID est 09CC-B4F2 n'existe plus. C'est pour ça que ton Ubuntu ne peut pas démarrer.

Re : Default Boot Device Missing redémarrage

Je crois comprendre comment j'ai fait cela... je doit réinstaller ubuntu ou il y a des moyens de récupérer cela ? si oui pourrait tu m'aiguillez pour mes recherche car je suis novice et j'avoue être un peu dépassé, peut être CGSecurity pour restaurer ma partition ?
