============================= Boot Repair Summary ==============================

Default settings: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub-efi of
sda2,
using the following options: sda1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file

Blockers in case of suggested repair: __________________________________________

The current session is in BIOS-compatibility mode. Please disable BIOS-compatibility/CSM/Legacy mode in your UEFI firmware, and use this software from a live-CD (or live-USB) that is compatible with UEFI booting mode. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode. This will enable this feature.

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.2 LTS entry (sda1/efi/****/grub****.efi (**** will be updated in the final message) file) !
The boot of your PC is in BIOS-compatibility/CSM/Legacy mode. You may want to retry after changing it to UEFI mode.

User settings: _________________________________________________________________

/usr/share/boot-sav/gui-scan.sh: line 554: warning: command substitution: ignored null byte in input
Please backup your data before this operation.
The settings chosen by the user will restore the [(generic mbr)] MBR in sda, and make it boot on sda2.
Additional repair will be performed: unhide-bootmenu-7s repair-filesystems

Force Unmount all blkid partitions (for fsck) except / /boot /cdrom /dev /etc /home /opt /pas /proc /rofs /sys /tmp /usr /var

Unhide GRUB boot menu in sda2/etc/default/grub

============================== Restore MBR of sda ==============================

dd if=/usr/lib/syslinux/mbr/mbr.bin of=/dev/sda
parted /dev/sda set 2 boot on
Information: You may need to update /etc/fstab.

parted /dev/sda set 1 boot off
Information: You may need to update /etc/fstab.
