我在用wubi安装的ubuntu 下使用mke2fs命令格式化一部分分区
由于我还装了mandriva2011;进入后发现
# df -h

Partition table entries are not in disk order



我怀疑是格式化了sda2:mke2fs -j -L "logical"/dev/sda2

重要数据没有丢失；而且我发现windows下能看到的磁盘都在；察看资源管理发现；
117.2G"硬盘驱动器为原D盘；ubuntu就是装在该盘上；119.0G硬盘驱动器为原G盘；里面有个人资料；12.0G"硬盘驱动和mandriva根目录相同；101.3G"硬盘驱动器为lost+found;DELLUTILITY应该是电脑的恢复驱动;logical就是我弄坏的分区,为lost+found；OS是原C盘

求如何恢复的方法；最好保留原数据；谢谢


开机grub选择进入windows显示:FILE system type unknown, partition type 0x7
Error 13: Invalid or unsupported executable format
怀疑是ubuntu的grub被破坏了

由于我刚刚学习linux；对磁盘不太了解；希望能有人帮助我确认问题所在；对症下药；谢谢了

另外提供以下我的 /boot/grub/menu.lst信息
linux(Mandriva)可以进入
