Bonjour, j'ai deux SSD, un avec windows 10 et l'autre avec ubuntu. Ca faisait des années que je n'utilisais plus ubuntu, j'y suis retourné dessus hier, c'est un vieux ubuntu avec rien d'important dessus et impossible de se connecter à internet. Donc j'ai voulu le mettre à jour en effaçant le disque et en installant la dernière version via une clé usb.
Je suis passé par le terminal de commande windows pour effacer le disque "ubuntu". je ne l'ai pas initialisé, je les laissé vierge.
J'ai éteint/rallumé l'ordi et là impossible de démarrer sur mon windows. Dans le bios si j'essaye de démarrer sur mon disque effacé (anciennement ubuntu) il me ramène au bios, et si j'essaye de démarrer sur mon disque avec windows je tombe sur cette erreur :
Error : no such device : "longue suite de caractère"
Error : Unknown filesysteme
Entering rescue mode...
Depuis mon mcbook j'ai créé une clé usb bootable avec ubuntu dessus et j'ai ensuite installé ubuntu sur mon disque vierge.
Je me retrouve maintenant avec ubuntu qui fonctionne sur mon pc mais toujours le même problème avec windows, impossible de l'ouvrir, ça m'affiche le grub rescue.
Voici le boot-info via ubuntu si jamais :
boot-info-4ppa2088 [20260304_1912]

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub2 of
sdb1 into the MBR of sdb.
Grub-efi would not be selected by default because legacy Windows detected.
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix
Blockers in case of suggested repair: __________________________________________
LegacyWindows detected. Please enable BIOS-compatibility/CSM/Legacy mode in your UEFI firmware, and use this software from a live-CD (or live-USB). 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.
Alternatively, you can retry after activating the [Separate /boot/efi partition:] option.
Confirmation request before suggested repair: __________________________________
LegacyWindows detected. The boot of your PC is in EFI mode. You may want to retry after changing it to BIOS-compatibility/CSM/Legacy mode.
Are you sure you want to continue anyway?
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your BIOS boot on sdb (ATA CT240BX500SSD1) disk!
The boot of your PC is in UEFI mode. You may want to retry after changing it to BIOS-compatibility/CSM/Legacy mode.
Si quelqu'un peut m'aider à refaire fonctionner windows par moi même, si c'est possible. Sinon je j'appellerais un dépanneur. Merci
