我有一台双启动的 Ubuntu 19.10 + Windows 10 笔记本电脑（详情如下），并且（UEFI）双启动运行良好。
我正在尝试通过实时 USB 重新安装 Ubuntu 19.10，但 Ubuiquity 抛出了错误“未找到 EFI 系统分区”。但是，我有一个 EFI 分区。看起来可能存在两个问题：
Ubiquity 将 ESP 分区 p1 归类为“Windows 启动管理器”而不是 ESP。请参见下面的屏幕截图。从日志和浏览 os-prober 脚本来看，如果分区中似乎有 Microsoft 引导加载程序，os-prober（/usr/lib/os-probes/mounted/05efi 和 /usr/lib/os-probes/mounted/efi/20microsoft）似乎无法识别 ESP 分区。有人知道这是为什么吗？或者如何解决错误？也许 Ubiquity 中的 os-prober 不是问题所在？
Ubiquity 无法将分区 3 识别为 Windows 10 分区。这可能是因为该分区使用了 bitlocker。我犹豫是否要关闭 bitlocker，因为担心这会破坏 Windows 安装。目前，Windows 和双启动运行良好，并且通过 Ubiquity 在 Windows 旁边安装 Ubuntu 的原始操作没有出现问题。
我的笔记本电脑是联想 X1 第六代，BIOS v1.46。这是分区表。分区 3 是 Windows 10，分区 5 是 Ubuntu 19.10。

我也尝试了启动修复。以下是有关该错误的更多详细信息。当我单击重新安装 Ubuntu 时，如下所示：
然后我收到此处显示的错误：
以下是 Uqiquity 显示的分区图。请注意，与 parted 和 gparted 不同，它不会将 EFI 分区视为 EFI 分区：
下面是 gparted 显示的相同分区图，表明在 p1 上设置了 boot 和 esp 标志：
