没有报错吗,加上 nosplash 参数看看启动的详细过程。

可能我没描述清楚问题,在说一次,刚安装上进行了一些省级,安了几个常用软件,当天好好的,第二天再开机,就不行了。进入grub 的菜单,选择ubuntu就出现下列错误:
error 17:can't mount selected partition ,press any key to continue
我按照论坛上的方法,用livecd 进行修复,详见前贴,可以进入系统了,但到晚上再开机,又不行了跟上午一样的情况,用livecd再修复,终端提示成功了,但重启还是不行
但是我的windows可以匆grub进去
楼上说的加什么参数不知道是什么意思,能否把详细的命令给出来。本人菜鸟,谢谢!
