最近我的系统出了不少问题，现在我遇到了一个问题。安装 Fedora 20 后，我尝试调整 Windows 7 分区的大小，结果分区的实际大小与引导扇区显示的大小不一致，出现了错误。为了解决这个问题，我使用 Windows 修复命令行删除了 MBR 和 BCD。然后，我再也无法进入恢复模式了。此外，我无法在 Fedora 系统上安装 NTFS 分区。
我在 Fedora 中运行了 ntfsfix，现在我可以挂载 NTFS 分区，但是我无法将其添加到 GRUB。
我运行了 bootinfoscript，结果如下：
Boot Info Script 0.61 [1 April 2012]

我的 Windows 7 分区位于 /dev/sda3，但请注意，它说没有错误。
然而，在bootinfoscript的结果的最后有：
=============================== StdErr Messages: ===============================

我不知道前三行是否与此有关。
在 sda1 上我有 Acer 恢复系统（恢复到出厂设置，这是我不想要的），而在 sda2 中有 Windows 的 /boot 分区。
我也尝试过解决方案在这里改变设置根=（hd0,1）和设置根=（hd0,2）和 设置根=（hd0,3）但我没有成功。
关于如何启动 Windows 7 系统，您有什么想法吗？
多谢！！！
