xp、ubuntu双系统，ghost xp后无法启动。一年前有类似帖子，没解决。看看现在能否解决。

U盘？试试看。"|"管道的命令是怎么用了，来个完整的命令行示意指导。谢谢。

现在不需要了。

看15楼，用工具软件修复。
手工修复要用winhex，要在整个硬盘找55AA标志，还要对分区表熟悉。

[蛋蛋痛]

testdisk要在win下运行，我我无法进入win（无论u盘上的还是光盘上的）。要有linux的解决办法。
我把
sudo fdisk -lu
sudo sfdisk -d /dev/sda
的输出做出来了。

sudo fdisk -lu

估计就是传说中的“循环的逻辑分区链”。

sda7结束扇区应该在35371008－63扇区，要证明还要读出来看。
sda6之后的分区全部丢失。
sda8后面分区是循环的逻辑分区链，都没用。
最好还是用分区工具恢复，如果数据重要最好找专业维修。

手工搞很麻烦的，要对分区表比较熟悉。我签名档有教程。
先要找到sda7结束扇区。
再找sda6结束扇区之后的分区。

能按http://forum.ubuntu.org.cn/viewtopic.php?f=139&t=153972，6 楼 billbear 说的去做吗？

[蛋蛋痛]

不好意思，没认真看。TestDisk是有linux版的。对不住onshoestring 的耐心解答了。

[蛋蛋痛]

testdisk没能完整运行。有什么方法能手动删除那些明显错误的分区，再用testdisk修复，这样的方案可行吗？

[错了吗]

找个U盘
或内存卡+读卡。

制成启动盘，进去后，找分区修复工具。

现在U盘启动制作工具很多，随便找一个，一会儿的功夫就可以弄出一个启动盘

比如进入PE，找个PTDD（分区表医生），修复分区表。

[蛋蛋痛]

只有ubuntu 10.04（其他linux没试）能进到可操作的界面，其他winpe，磁盘修复盘都死机。不过经过长时间的磁盘操作，我的riad卡，有问题了。现在不知道是单纯的接触不良，还是烧掉了。

[蛋蛋痛]

卡挂了。
