为什么在启动修复期间会显示错误？仅供参考：我的外部硬盘大小为 4TiB。
错误：不支持 4096 扇区大小

它不是 EFI，而是 BIOS 可启动：
ubuntu@ubuntu:~$ efibootmgr
EFI variables are not supported on this system.
我已经关注这关于 BIOS-GPT Linux 分区过程的文章。博主确认了使用基于 BIOS 的机器在 GPT 分区磁盘中进行此类安装的可能性。
我尝试过 BIOS-GPT（选项 1 和 3）。这些选项都无法启动 Linux 以及之前安装在内置硬盘上的另一个操作系统 (Win7)。
启动修复工具给出以下结果：
两个选项均显示：
