求助 invalid partition table
如题 好好的 重启之后忽然出现invalid partition table ,我的本本是双系统。新本本才买一个月.系统是win7和ubuntu,今天刚装完u的显卡驱动然后重启,,,就出现了这个问题。我用win7启动光盘直接修复是否就可以了?这个应该不是分区表坏了吧?只是mbr的问题吧?我的grub是写入mbr的.我的分区是 sda1sda2是ubuntu的根分区和交换分区,sda3是win7分区,都是主分区

分区表损坏,试试testdisk。
我不是什么大神,就是灌水多些。
无损改变分区大小的分区工具少用。
备份分区表,而不是分区表出现问题再找软件恢复。

恩 谢谢啊 testdisk
