=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to sign-grub enable-lvm) and reinstall the grub-efi-amd64-signed of mapper/ubuntu--gnome--vg-root, using the following options: nvme0n1p2/boot, nvme0n1p1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file rename-ms-efi
=================== Advice in case of suggested repair
Si consiglia di riprovare dopo aver decriptato le partizioni. (https://help.ubuntu.com/community/EncryptedPrivateDirectory)
Continuare?
=================== Final advice in case of suggested repair
Non dimenticare di impostare la priorità di avvio nel BIOS al disco mapper/ubuntu--gnome--vg-root (247GB)!
=================== User settings
The settings chosen by the user will not act on the boot.
