grub2-install 失败，错误为“efibootmgr：选项需要参数 --‘d’”

Question

我尝试在磁盘上安装 grub2，但总是失败并显示以下错误消息。但是它确认安装已完成，但没有更新 efi 启动项。我必须手动加载内核和 initrd 才能在重启时从 grub shell 启动。

我尝试手动添加 efi 启动项，但仍然进入 grub shell。此处报告了相同的问题：https://bugzilla.redhat.com/show_bug.cgi?id=1758621但似乎没有办法解决这个问题。有人能帮我解决这个问题吗？我使用的是 CentOS Linux 版本 7.9.2009（核心版）。
