Ok je résume et désolé si je ne suis pas trop performant mais je ne suis pas vraiment à l'aise avec ce genre de problème, la je suis sur ubuntu (sdb) et la fedora que j'ai installé hier est sur sda mais je ne la voit pas dans le menu de boot et je ne vois qu'un systeme de fichier de 524mb avec dedant entre autre un dossier grub et le grub.conf est
# grub.conf generated by anaconda

donc j'avais rajouté l'entrée ubuntu a la main hier ça n'est donc pas écrasé
ensuite puisque je n'avais pas la possibilité de booter sur ubuntu
error 13 invalid or unsupported executable format
je suis passé en live cd et j'ai fait
sudo mkdir /media/seagt
sudo mount /dev/sdb1 /media/seagt
sudo grub-install --root-directory=/media/seagt /dev/sda
maintenant le grub.cfg de ubuntu est (il n'as pas bougé en fait)

bon hier j'ai renommé 50055d8d-21f7-412c-bd49-9e759283b48a en seagt avec
sudo tune2fs -L seagt /dev/sdb
voila si je peux être plus clair ou apporter d'autres précisions je veux bien essayer
à moins que j'ai vraiment tout cassé, ce que je ne comprend pas c'est pourquoi je suis en amorce sur sda alors que mon ubuntu est sur sdb, en fait y'as pas mal de choses que je ne comprend pas, 🙁
