GRUB - Impossible de le lancer

Bonjour à tous,

Pour des problèmes de compatibilité je voulais lancer Ubuntu sur un noyau plus ancien que celui que j'ai actuellement. Voulant ainsi accéder au GRUB, je me suis rendu compte que je n'arrivais pas à l'ouvrir.
En faisant un Boot-Info, voici les données :

 => Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of 
    the same hard drive for core.img. core.img is at this location and looks 
    for (,msdos1)/boot/grub. It also embeds following components:

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda1 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (ATA KINGSTON SUV400S) !

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 16.04.3 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


=================== User settings
The settings chosen by the user will not act on the boot.

Pour faire apparaître Grub au démarrage, il y a deux solutions :
1) pour le faire apparaître temporairement : il faut presser la touche Shift au démarrage de l'ordi
2) pour le faire apparaître systématiquement : applique ce post #3 puis le post #4 qui suit

Re : GRUB - Impossible de le lancer

Je voudrais le faire apparaître temporairement mais la touche Shift au démarrage ne fonctionne pas... Je tombe directement sur Ubuntu.
