我刚刚搞定了 Windows 7 + Linux Mint 双启动，终于让它正常工作了。Grub 负责启动。只要我只连接了主硬盘，它就能正常工作。
当我连接第二个硬盘并启动笔记本电脑时，会出现介绍屏幕，然后，没有 grub，只有空白屏幕（不知为何，笔记本电脑的风扇开始疯狂转动）。没有其他内容。当我第一次启动 PC、启动操作系统，然后才连接第二个硬盘时，它会被顺利识别。
我尝试在两个驱动器都连接的情况下运行启动修复，但问题仍然存在。这可能是什么原因造成的？
两个驱动器都是 SATA。

编辑2 - 我尝试了另一个辅助硬盘。我格式化了该硬盘，但它上面没有任何分区。只有未分配的空间。但电脑仍然无法启动。
我愿意接受任何建议，我愿意格式化/擦除任何东西以使其正常工作。
另外，在安装时，Linux Mint 无法识别现有的 Windows 安装，因此我必须手动对驱动器进行分区，然后运行启动修复才能使其正常工作。
答案1
如果第二个硬盘上的 MBR 的引导区域中有引导加载程序数据（即使 BIOS 中的引导顺序设置正确），就会发生这种情况。
如果您现在或将来不需要从第二个驱动器启动，则可以使用以下命令安全地擦除前 446 个字节：
dd if=/dev/zero of=/dev/{第二个驱动器} bs=446 count=1
您需要将上面的 {second drive} 替换为 /dev 中正确的对应条目，例如 /dev/sdb
