Problèmes de démarrage d'Ubuntu après élimination de partition

Bonjour
Voyons si Je me fais comprendre
J'avais Kubuntu 16.04 sur un disque SATA "normal". J'ai acheter un "disque" ssd et y ai installé Kubuntu 16.04.2. Et j'ai éliminé la partition où, chez l'autre disque ( où j'ai d'autres partitions, avec des données) j'avais la première version de kubuntu 16.04.
Cependant, maintenant, mon ordinateur persiste à  démarrer sur le disque ancien et - naturellement - il me dit qu'il n'y voit pas de partition, donc de grub. Je dis " persiste" parce que J'ai déjà modifier la BIOS pour la faire démarrer sur le ssd, mais sans résultât.
Il me paraît donc qu'il y a deux problèmes: le premier, le fait que la BIOS ne suive pas mes instructions, et le second que, le boot ancien étant  sur le début du disque et non sur la partition système éliminée, il faudra l'expulser. Si Je vois bien, il y a une chose que Je ne sais pas faire: enlever le boot du disque ancien.
Merci

Merci
Voici le boot info. Mais Je ne comprends pas les dates. Aujourd'hui c'est le 24 Avril 2017
Le disque en question est le dev/sde, qui n'a pas de partition système.

Boot Info Script cfd9efe + Boot-Repair extra info      [Boot-Info 26Apr2016]

Voici ce qui est  écrit dans le document

    Notez sur un papier l’URL (paste.ubuntu.com/XXXXXX/) qui apparaît, et indiquez cette URL aux bénévoles qui vous aident par email ou forum.

Ici, j'ai un vague copier/coller du début   qui ne me permet pas de voir ce que "boot-repair" aurait pu proposer comme méthode de réparation.

Re : Problèmes de démarrage d'Ubuntu après élimination de partition

Ici, j'ai un vague copier/coller du début   qui ne me permet pas de voir ce que "boot-repair" aurait pu proposer comme méthode de réparation.

Bonjour
Je m'en excuse mais Je ne comprends pas ce que tu veux. Mon copier-coller n'est pas  seulement du début, mais de tout ce qui m'a donné ma commande sur le terminal. Aussi Je ne comprends pas ce que Je dois noter sur un papier et pourquoi, une fois que Je suis sous un autre disque.
Merci
