Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would restore the [(generic mbr)] MBR in nvme0n1, and make it boot on nvme0n1p1.
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix
Moi j'y vois que tu patauges gravement. Le principe de la bonne cohabitation des OS dans un ordi, c'est que tous les OS soient installés dans le même mode. Là je vois que ton Windows est installé en mode Bios classique (non-EFI) donc il faut que Ubuntu que tu vas installé, soit aussi dans ce mode Bios (non-EFI). Pour que ce soit le cas, il faut que le démarrage sur le support d'installation de Ubuntu soit dans le mode Bios (non-EFI). Là ce n'est pas le cas : on peut voir écrit en clair dans le Boot-info :
===================================== UEFI =====================================
BIOS is EFI-compatible, and is setup in EFI-mode for this live-session.
C'est à dire que la session Live a été démarrée en mode EFI. Donc ce n'est pas bon.
