我最近重新安装了 Windows，Windows 是一个很棒的操作系统，它会删除引导加载程序。我认为这很容易修复，但我只需用 Manjaro 刷新我的拇指驱动器并启动它即可。当我尝试时grub-install /dev/sda4，它出错并说找不到 EFI 目录。接下来，我尝试执行grub-install --target=i386-pc /dev/sda4，它说它无法获取覆盖的规范路径。我现在有点困惑，所以我尝试挂载所有内容，chroot 到/mnt，然后grub-install /dev/sda4再次运行。这导致 grub 说该系统不支持 EFI 变量。我尝试退出 chroot，运行modprobe efivarfs然后执行efivar-tester，它还告诉我不支持 EFI 变量。我回到 chroot 并尝试grub-install --target=i386-pc /dev/sda4，它说File systemext2' 不支持嵌入。无法嵌入。只能使用黑名单在此设置中安装 GRUB。但是，黑名单不可靠，不鼓励使用它们. I tried exiting chroot again and mounting /dev/sdsa1 which appeared to be an EFI partition to/mnt/boot/efi`。我回到 chroot 并再次尝试安装两个 grub，都出现相同的错误。我尝试了在线找到的所有方法，但似乎都不起作用，有人能帮我吗？

我通过重新启动并尝试以下命令解决了该问题：
sudo mount /dev/sda4 /mnt
sudo mount /dev/sda1 /mnt/boot/efi
manjaro-chroot /mnt /bin/bash
pacman -Syu grub
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
grub-mkconfig -o /boot/grub/grub.cfg
