Partition table entries are not in disk order.
=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda6 into the MBR of sda.
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s
=================== User settings
The settings chosen by the user will not act on the boot.
On y voit cette ligne :

J'ai fait une recherche avec Google sur "976,740,352 976,773,119 32,768 ef EFI (FAT-12/16/32)" et je suis tombé sur plusieurs résultats dont celui-ci qui concerne le même modèle d'ordi que toi ( ASUS Eee PC 1225B ) :

Donc cette partition, ce n'est pas toi qui l'as créée. Elle est d'origine. Cela dit, elle ne sert à rien à présent et tu peux la supprimer ainsi que l'autre partition EFI (/dev/sda5) qu'on peut voir dans ce extrait de ton Boot-info :
/dev/sda5 * 491,030,528 492,079,103 1,048,576 ef EFI (FAT-12/16/32)
Pour supprimer ces deux partitions, je te conseille d'opérer depuis une session live de Ubuntu avec Gparted parce que Gparted fait partie des logiciels disponibles en session live.
