GRUB menu disappeared after Clonezilla backup

[bpan]

Hi
I have very similar problem as the one described in the post GRUB disappeared after attempt to recover.

I have dual boot Win 8.1/Manjaro system. After Clonezilla whole-drive backup, GRUB startup menu disappeared completely and the system has been booting directly into Windows.

I tried the instructions from the GRUB /Restore the GRUB Bootloader
Wiki page but got stuck.

After several unsuccessful attempts (had to do the full set of commands as the base solution didn’t work) I managed to get all the way to the last step ‘sudo update-grub’ which came up with similar error message as in last section of the quoted post above (cannot find GRUB for dev/sdb1), which suggests that the Grub was not updated properly.

Upon restart of the system, the GRUB menu showed up, however, it only has a single option which is Windows (the boot loader is EFI/Manjaro/grubx64.efi). Now I am stuck how to get the Manjaro system option as well as the other two standard menu items (memtest and advanced).

My ext4 partition is sda6 and my vfat (efi) partition is sda2

Any help is much appreciated. Thanks!

Here are some outputs:

I would like to add that initially I was able to start the original system via Detect system bootloaders menu item on the Manjaro USB live install and selecting EFI/Manjaro/grubx64.efi option from the list.

After the above procedure, this option also shows a single item which is Windows.

If you’ve booted up from the live medium, open up a terminal and type the following command…

su -

Enter the root password for the medium, and then issue the following commands. Be sure to let them finish.

mount -t ext4 /dev/sda6 /mnt
mount -t vfat /dev/sda2 /mnt/boot/efi
manjaro-chroot  /mnt
pacman-mirrors -f 5 && pacman -Syyu
grub-install --recheck --no-rs-codes --efi-directory="/boot/efi" --target="x86_64-efi" --modules="part_gpt part_msdos zstd"
update-grub
sync
exit

After this, you should be able to reboot, and Manjaro should now be added to the GRUB menu again.

Bingo - all worked perfectly!

Upon the first restart there were duplicate entries for Manjaro and UEFI Firmware.

Once I got to my Manjaro System, I started the GRUB Customizer (I know, some people do not recommend using it) which detected duplicate entries and removed them upon Update and Quit.

All good now!

Thanks a lot!
