进不了fc4的问题

troy03

双系统，从硬盘装的fc4，安装很顺利.启动后显示内容摘录如下：
          Welcome to Fedora Core
Initialzing hardware...storage  network audio  done
[mntent]:line 6 in ect/fstab is bad,rest of file ignored


setting up Logical volume Management:
NO volume groups found


WARNING:bad format on line 6 /ect/fstab
/has gone 49709 days without being checked

Enabling local filesystem quotas:
Enabling swap space:

sh-3.00#
然后就不动了，键盘无效。

各位帮我看看怎么办呀  先谢谢大家了
