嘿伙计，我一直在努力设置双启动，我需要一些帮助。我刚买了一台新电脑，我做的第一件事就是安装了一个 SSD，并在其上安装了 Windows 10。所以我正在使用的是一个装有 Windows 10 和一个非常大的 HDD 的 SSD。我想在我的 HDD 上安装 ubuntu，并能够双启动它，同时仍将大部分 HDD 用于 Windows 家庭用户类型的内容。
我已经用几种不同的配置安装了几次 ubuntu，但它总是只能启动到 windows。bios 无法识别硬盘是否可启动。我尝试了几种不同的“分步”方法，但似乎都不起作用。
我有一个很大的 RESULTS.txt 文件，是我在使用记忆棒中的 ubuntu 尝试解决此问题时从 bootinfoscript 获得的，我可以为您提供几乎所有您需要的其他数据。不确定您是否想要。bootinfo 相当大，如果您想要一个部分，请告诉我要发布哪个部分。
以下是fdisk -l：

答案1
经过一番挖掘，我找到了答案。在 Windows 中以管理员身份运行 CMD 并使用此命令：
bcdedit /设置 {bootmgr} 路径 \EFI\ubuntu\grubx64.efi
