我是 Linux 新用户。当我安装 Ubuntu 20.4 和 Windows10 双启动时，我在启动 PC 时遇到问题。现在，当我启动 PC 时，GNU Grub 页面打开并显示以下消息：Minimal BASH-like line editing supported。
我已经尝试过通过实时 USB 进行 Boot-Repair，但它没有为我的 PC 打开 Boot-Repair 选项，因此我无法通过这种方式运行 grub。我还在这里提供 Boot-Repair 启动信息摘要供您参考。

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would not act on the MBR.
Additional repair would be performed: win-legacy-basic-fix
