对不起，我还是要问一下升级11.04后win7分区消失的问题

[reignlw]

之前是win7+ubuntu10.10 用的grub，一直相安无事
不知道为什么，昨天晚上dist-upgrade到了11。04，结果问题就出现了，在grub.cfg里面再也找不到win7分区的信息了。

本来win7是安装在sda1分区上面的，但是目前ubuntu却完全找不到其启动信息了，请问我该怎么办呢？

老版简单，自己加一下

grub2是有点二

看置顶贴吧

11.04的Bug？

[smallapple]

大概是win7分区的启动扇区挂掉了，有win7安装光盘的话，用安装光盘启动，进修复模式命令行下执行
bootrec /fixboot
试试

或用WinPE光盘启动，找个 bootice.exe重写下win7分区的引导扇区。

看磁盘信息，分区并没有消失，只是不能引导了。修复WIN7引导既可以了。
