grub "error: command failed" after 20.04.03 kernel upgrade

Question 1

Я использую 20.04.03. Я обновился до linux-image-5.11.0-27-generic. Перед перезагрузкой я сказал "apt autoremove". Теперь, когда я включаю машину, она не загружается. Я получаю экран меню grub, где по умолчанию стоит "Ubuntu". После тайм-аута он говорит "ошибка: команда не выполнена" 5 раз, а затем "error: you need to load the kernel first".

Если я нажму ESC, появится приглашение grub>. Если я набираю exit, он возвращается на экран меню и на этот раз загружается правильно.

Я попробовал grub-install, но это не помогло. Я попробовал создать новый grub.cfg с помощью grub-mkconfig, но он не отличается от того, что у меня был.

Вот мой grub.cfg:

Question 2

Надеюсь, ваш sda7 является установочным разделом, а sda1 - efi. загрузите live cd / pendrive откройте терминал и введите эти команды * построчно.

sudo mount /dev/sda7 /mnt
sudo mount /dev/sda1 /mnt/boot/efi
sudo rm -r /mnt/boot/efi/*
for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt
grub-install /dev/sda
update-grub
exit
reboot
