Ghost恢复后Windows 7无法启动解决

最近用Ghostt恢复Windows 7成功后，重新启动操作系统时，无法进入系统，光标在左上角一下闪，用启动U盘进行尝试引导到硬盘启动，有以下界面，还是直接显示无法引导。 File:\Boot\BCD Status: 0xc000000e Info: An error occurred whiel attempting to read the boot configuration data. 参见U盘安装WIN10时显示 windows无法安装到这个磁盘选中的磁盘采用GPT分区形式，找到以下解决办法。原因是在Ghost恢复之前有安装过Linux操作系统，硬盘被格式化为UEFI引导，而硬盘是MBR的，UEFI引导是和GPT硬盘相对应的，所以要转换MBR硬盘为GPT硬盘。转化为GPT硬盘后（需要重新格式化），重新做Ghost恢复，问题解决，系统可以正常引导。 Reference U盘安装WIN10时显示 windows无法安装到这个磁盘选中的磁盘采用GPT分区形式
