Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would not act on the boot.
On y voit que ton modèle d'ordi est équipé du système Optane H10 (*). Il va falloir que tu désactives Optane H10. Cela se fait depuis une session de ton Windows 10.
EDIT : des explications sur les manips à faire sont données par alexandre_caze dans ce post :
https://forum.ubuntu-fr.org/viewtopic.php?pid=22403411#p22403411
A priori, tu n'as pas à changer ce qu'il y a actuellement dans le Bios. C'est à dire que le paramètre
SATA Mode Selection est certainement sur
[Intel RST Premium With Intel Optane System Acceleration] et il convient de le laisser comme ça.
(*) les symptômes de Optane H10 quand il est activé : la présence de md/imsm1 au début du Boot-info.
