我知道以前也出现过类似的问题，但到目前为止我发现的一切都无济于事（部分原因是我无法理解其中的大部分内容）。所以我们开始吧：
Windows 10 开始自动安装。我使用 ls (HD0) 重新启动时 Grub 安全。(HD0,msdos1)... 直到 5（所有无法识别的系统）。我尝试了 Boot-Repair-Disk（推荐）。它说它已经修复，但实际上并没有，我仍然得到同样的结果。
启动信息摘要如下（由于 30k 字符的限制，我删除了十六进制转储）。末尾处写着The default repair of the Boot-Repair utility will not act on the MBR. Additional repair will be performed: repair-filesystems。我还不敢做任何事情，因为担心情况会变得更糟。
顺便说一句，该特定机器上的 Ubuntu 分区实际上并没有使用，所以我毫不犹豫地牺牲它。
