由于我在某次启动的过程中碰到了"erro:invalid environment block"错误，在google上搜到了解决办法，我转述一下，希望对大家有帮助

1、在启动grub的界面按“e”，找到"save_env"，删除整行
2、执行ctrl+x启动系统，此时你应该能进入x了
3、执行如下命令，貌似要用sudo

代码:
cd /boot/grub
rm grubenv // 成功了
grub-editenv grubenv create // 失败~!!好像说grub-editenv 没找到,下面几步也不行
grub-editenv grubenv set default=0
grub-editenv grubenv list
default=0


4、执行下面命令，修复grub菜单

代码:
sudo update-grub //这个倒是没问题....

smallapple 写了：Livecd进去改grub.cfg。
