编译安装完重起之后出现Kernel panic-not Syncing:VFS:unable to mount root fs on Unknown-block(3,4)

grub.conf 文件内容如上, 但是没有办法起动,开机提示如下

Kernel panic-not Syncing:VFS:unable to mount root fs on Unknown-block(3,4)
把root后面的所有的东西都删掉后还是出现Kernel panic-not Syncing:VFS:unable to mount root fs on Unknown-block(3,4)
这是什么问题？请那位给与解决？

首先监察是否把根文件系统编入了内核
