我的Debian Jessie的安装运行良好,但随后运行了apt-get update && apt-get upgrade && apt-get dist-upgrade
。
然后重新启动后,它直接进入BIOS。我意识到Grub不见了,所以我运行了一个cd并进入Rescue mode
,安装了我的根分区,再加上了启动分区并运行了以下命令:
Grub找到了Linux映像:
root@debian:~# update-grub

Adding boot menu entry for EFI firmware configuration
done
然后grub-install
:
root@debian:~# grub-install /dev/sda
Installing for x86_64-efi platform.
Could not prepare Boot variable: No such file or directory
grub-install: error: efibootmgr failed to register the boot entry: Input/output error.
lsblk
:
root@debian:~# lsblk

我做错什么了吗?/boot/efi
分区上的空间是否太小?
root@debian:~# ls -l /boot/efi/EFI/debian/
total 120
-rwx------ 1 root root 121856 Jul 20 20:29 grubx64.efi
efibootmgr
不显示Debian安装:
root@debian:~# efibootmgr --verbose | grep debian
编辑:
每次尝试使用efibootmgr
以下命令创建引导加载程序时,我都会不断收到此错误:
grub-install: info: executing efibootmgr -c -d /dev/sda -p 3 -w -L grub -l \EFI\grub\grubx64.efi.
Could not prepare Boot variable: No such file or directory
grub-install: error: efibootmgr failed to register the boot entry: Input/output error.
