grub-install: Fehler: EFI-Verzeichnis kann nicht gefunden werden.

Cannot find EFI directory: issue with grub-install


Wenn Sie grub-install standardmäßig ausführen, wird davon ausgegangen, dass das EFI-System als /boot/efi gemountet ist.Es hängt von Ihrer Distribution ab, wo das EFI-System gemountet ist, und bei einigen Distributionen wird es nach dem Booten nicht gemountet.

Überprüfen Sie zunächst, ob /boot/efi mit gemountet ist

mount | grep /boot/efi

Wenn das nicht funktioniert, versuchen Sie zunächst Folgendes, um festzustellen, ob es woanders gemountet ist.

mount | grep /dev/[efi-Gerät]

Wenn keine dieser Arbeiten funktioniert:

Mounten Sie /dev/[EFI-Gerät] /mnt

Führen Sie nun Folgendes aus:

grub-install –efi-directory=[efi dir]
grub-mkconfig -o /boot/grub/grub.cfg

Dabei ist [efi dir] entweder /boot/efi oder /mnt und [efi device] das Gerät mit der EFI-Systempartition. Wenn Sie es nicht wissen, verwenden Sie den Befehl lsblk -o NAME,PARTTYPE,MOUNTPOINT | grep -i „C12A7328-F81F-11D2-BA4B-00A0C93EC93B“
