在另一个磁盘上安装 Fedora 38 后如何恢复 Windows 启动选项

我刚刚在我的额外 SSD 上安装了 Fedora 38，但安装后，我无法启动 Windows 10。甚至 Windows 启动管理器选项也从 BIOS 中消失了。

我找到了一些关于如何手动将其添加到 grub 的帖子，但我甚至无法获取 UUID。

os-prober 也无法检测到窗口：

在 /dev/nvme0n1p2 中找到 EFI 文件夹，该文件夹具有 NTFS 文件系统 在此处输入图片描述

答案1

由于缺少 EFI 分区，因此我使用 Windows 安装媒体重新创建了它。

当出现选择语言向导时按下shift + f10，输入命令提示符然后：

diskpart

list disk
// choose disk carefully 
select disk 0

list partition
// choose partition carefully 
select partition 2
// shrink another partition to give ESP sapce
shrink desired =600

// now create the ESP 
create partition efi

// format it as FAT32
format fs=fat32 quick


assign letter=Y

exit

// fill ESP with EFI files...
bcdboot c:windows /s Y:
