Forum Linux.noyau Problème installation Zorin OS

Bonjour, suite a un soucis avec Windows 10 que je ne peux plus lancer sur mon ordinateur. J'ai donc décidé de me tourner vers Linux et plus particulièrement Zorin.

Malheureusement, lorsque je veux passé a l'installation, j'ai ce message d'erreur : " partitions 2, 4 have been written, but we have been unable to inform the kernel of the change, probable because it are in use. As the result, the old partitions will remains in use. You should reboot now before making further changes ", j'ai donc fait des recherches avant de passer par ce forum qui n'ont pas été concluantes.

Je joint ici un Boot-info afin que vous ayez plus d'info. Merci d'avance

Cordialement
