problème de démarrage [RESOLU]

Bonjour, suite a une mise a jour de grub ( sudo apt update) sur Pop_OS !  je crois que j'ai fais une bêtise et je l'ai installé sur la mauvaise partition, j'ai lancé un boot repair qui m'a retourné ceci :

j'ai accès au bios, et quand je démarre il me propose mon disque  dur  j'ai beau appuyer sur entrer ça me renvoie instantanément sur le menu.

Le boot repair sur clé ( avec ubuntu) ne me propose pas d'options du grub,

j'ai essayé quelques choses sur ce topic sans grand succès

https://forum.ubuntu-fr.org/viewtopic.p … 1#p7201291

et la documentation     https://doc.ubuntu-fr.org/tutoriel/comm … aurer_grub       j'ai peur d'empirer la situation

merci beaucoup, je suis un peu dans la mouise =(

Re : problème de démarrage [RESOLU]

Bonsoir.
Je te propose de voir si, en utilisant le programme gparted du support d'instattation, tu supprimes le drapeau boot de la partition sda2 et en le mettant sur la paértition sda1, il y a une amélioration.
