ubuntu fsck修复分区

屏幕错误提示：

No init found. Try passing init= bootarg

Busybox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu7) built-in shell (ash)

1.从Ubuntu10.04 live CD引导系统；（ 首先用u盘制作一个Ubuntu的live CD（请自行搜索 http://www.linuxidc.com），然后通过u盘启动， 选择try ubuntu, 进入live CD系统）
2.打开命令行；（控制终端）
3.运行"sudo fdisk -l"回车，目的是查看设备名称。输出类似于：
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: **********
Device Boot Start End Blocks Id System
/dev/sda1 * 1 30238 242886703+ 83 Linux
/dev/sda2 30239 30401 1309297+ 5 Extended
/dev/sda5 30239 30401 1309266 82 Linux swap / Solaris
选择Linux所在分区: /dev/sda1。如果/boot单独分区了则选择/boot所在分区。（我个人认为）
4.运行"sudo fsck /dev/sda1"回车;
5.出现 Free blocks count wrong for group #3(31232, counted=31224).
Fix?
Y Enter
根据实际情况，可能还需要再执行几次fsck，直到最后提示“clean”为止，表示该文件系统已经完好无损：
6.重启电脑，正常引导系统。
