无法修复 bcd，因为找不到 windows 安装

Question

我正在尝试重建我的 BCD，但找不到我的 Windows7 安装。

到目前为止，我已经从 Windows7 安装 DVD（以 UEFI 模式启动）输入了以下命令：

X:\sources>chkdsk /r c:
X:\sources>bcdedit /export C:\BCDBackup
The operation completed successfully.
X:\sources>attrib c:\boot\bcd -h -r -s
X:\sources>ren c:\boot\bcd bcd.old
X:\sources>bootrec /rebuildbcd
Scanning all disks for Windows installations.

Please wait, since this may take a while...

The operation completed successfully.
X:\sources>attrib c:\bootmgr -h -r -s
X:\sources>ren c:\bootmgrbackup
X:\sources>bootrec /rebuildbcd
Scanning all disks for Windows installations.

Please wait, since this may take a while...

仍然找不到 Windows。

这里有一些关于我的电脑的有用信息（我从法语版 Windows 安装 DVD 启动），因此，您会注意到我已尽我所能将其翻译成了英文：
