我的ubuntu搞坏了，哪位大侠可以指导我修复一下

原本什么都好用的，当我用sudo halt关机后再回来，启动的时候硬盘检测卡住了，大约有1分钟，我不知道是怎么回事，我重启，现了以下问题，
这是我抄下来的全屏提示

请大家帮帮我，不胜感激~~~！！

root@ubuntu_717:~#
就在这里输入fsck /dev/sda1
整完了再输入exit

上面说很清楚啊。
你root登录后，不是提示进入系统了吗？
然后RUN fsck manually
(i.e., without –a or –p options)

让你在root下再fsck一次。

别进不到图形界面就认为没有登录成功。

smallapple, smallapple,
谢谢你 ，同时我这台还是一个DHCP服务器，系统提示
starting DHCP server dhcpd3
check syslog for dianoistics. [failed]
我这台机器有两个网卡，DHCP以前就做好了，我试了一下是好用的，现在不知道为什么服务器的DHCP不好使了，请问怎么办？

看这个能不能帮上忙
