我刚入门,我用的是U盘安装ubuntu-14.04-desktop-amd64,已经装了win7系统。用U盘安装的时候也遇到楼主的问题,后来弄了半天时间才做好了。
方法是:先用DiskGenius将要安装的空闲磁盘转换格式为FAT32,然后用U盘重新启动,进入Ubuntu安装界面,这时候可以看到不只有一整块空闲磁盘,而是分成了几部分,这样选中FAT32格式的磁盘,点击“-”将其移除使其成为空闲磁盘,之后就可以安装了。

@billbear 大神求助

我在win8.1基础上安装双系统的时候,使用了您在本帖12楼提供的指令:sudo dd if=/dev/zero of=/dev/sda bs=1 count=8 seek=512

然后windows进不去了。。。

请问如何恢复GPT信息?恢复了应该就可以进到windows了吧?
