系统出错了。开机时在那个滚动栏下面出现
Routine check of drivers : /dev/sda7
之后变进入黑色的界面，写着：
checking drive /dev/sda7:2%(stage 1/5 , 1/30)
/dev/sda7:Inodes that were part of a corrupted orphan linked list found.
/dev/sda7 UNEXPECTED INCONSISITECY;UNEXPECTED INCONSISITECY;RUN FSCK MANUALCY (i-e,withoutte -a or -p options)
fsck died with exit status 4 checking drive /dev/sda7:4% (stege 1/5 ,2/30)
...fail
.......
解决方法：进入安全模式，输入：fsck -sV /dev/sda7 修复文件系统。
