最初，我想在 UEFI 中安装 Fedora，但不知道出于什么原因，我收到了一条消息“对于 UEFI 安装，您必须在 GPT 格式的磁盘上包含一个 EFI 系统分区，该分区位于 /boot/efi”。奇怪的是，当我在 UEFI 模式下启动时，它无法检测到我的硬盘。
因此我决定以传统模式安装 Fedora，它运行良好，但 Grub 没有出现。
我的 fdisk：
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 1026047 1024000 500M 7 HPFS/NTFS/exFAT
/dev/sda2 1026048 409599999 408573952 194.8G 7 HPFS/NTFS/exFAT
/dev/sda3 409600000 410623999 1024000 500M 83 Linux
/dev/sda4 410624000 976773119 566149120 270G 5 Extended
/dev/sda5 410626048 741892095 331266048 158G 8e Linux LVM
当我这样做时，grub-mkconfig -o /boot/grub2/grub.cfg
它确实找到了我的所有分区
Found Windows 10 (loader) on /dev/sda1
我执行了 grub2-install /dev/sda，但也没有起作用。
的结果bootinfoscript
