有时前我必须在按下 Lenovo（v580 笔记本电脑）Windows 8 系统恢复按钮后恢复 Linux 启动（只是一个愚蠢的错误）。然后我就按照这个指南进行了操作http://community.linuxmint.com/tutorial/view/245。虽然我现在可以在每个软件更新（任何软件）上从 Linux 分区启动，但我可以看到错误，我可以通过以下命令执行来重现该错误：
mypc html # dpkg --configure grub-efi-amd64-signed
Setting up grub-efi-amd64-signed (1.34.2+2.02~beta2-9ubuntu1.1) ...
grub-install.real: error: /usr/lib/grub/i386-pc/modinfo.sh doesn't exist. Please specify --target or --directory.
dpkg: error processing package grub-efi-amd64-signed (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
grub-efi-amd64-signed
我尝试重新安装grub-efi-amd64-signed软件包，但这没有帮助。
我正在使用 Linux Mint 17 64 位
更新
在BIOS中设置为启动Legacy+UEFI（Legacy优先）。
当前安装的 grub 软件包：
mypc html # dpkg -l grub\*

答案1
我在 Dell Latitude E7450 上遇到了同样的问题。我只是跑了
sudo apt-get install grub
sudo apt-get autoremove
从标准 shell 中就可以了。
