崩溃之前，我在同一个 SSDSCKKW480H6 Intel 480GB 硬盘上安装了 Ubuntu 22.04 和 Windows 10 双启动。
我打算制作一个 Windows 可启动恢复映像，然后清除所有内容并单独启动 Ubuntu，但我有一些 Windows 更新，看到我可以升级到 Windows 11，并尝试了。在 Windows 11 下载/升级过程中，我收到蓝屏错误，计算机重新启动，但我收到了一条no bootable device found错误消息。
只要我能重新使用我的 SSD，我很乐意丢失 Windows 和 Linux 分区上的所有数据。
BIOS 菜单，或者至少是我可以通过按 F1 到 F12 键访问的唯一菜单是一个设置 GUI，我可以在其中调整启动顺序和时钟速度，但实际的 SSD 并没有显示为任何可启动的内容。
我从实时 USB 启动并尝试了 Boot-Repair（建议的修复是“Boot-Repair 实用程序的默认修复不会在启动时起作用”），但是 Boot-Repair 文本文件确实表明 Windows 已安装在 的 MBR 中/dev/sdc。
sdc1：
- 全部空白
sdc2：
- 文件系统 ext4
- 其余空白
sda：
- 文件系统 iso9660
- 引导扇区类型 grub2 vXX
- 引导扇区信息：grub2 vXX 安装在 sda 的引导扇区中，并在同一硬盘的 0 扇区中查找 core.img，但在此位置找不到 core.img。
安装失败：mount：/mnt/BootInfo/FD/sda：/dev/sda 已安装或安装点繁忙。

同样，一个简单的“清除所有内容”命令此时将是一个很棒的解决方案，但是如果有办法访问 Linux 分区上的几个最近的文件和/或检索我的 Windows 许可证信息，以便我可以在需要时再次安装 Windows，那也会很棒。
如果我不得不猜测的话，我确实认为根本原因是 Microsoft 分区不是 GPT，而这恰恰是 Windows 11 的要求，但这不是重点。
