我按照这里的说明进行操作 -在具有 UEFI BIOS 的机器上安装具有 RAID 1 和 LVM 的 Ubuntu 20.04 桌面但使用 Ubuntu 服务器安装程序来配置分区布局，并增加了创建由 LVM 管理的加密分区的额外步骤，
安装并重新启动后，它只会将我带到 grub 提示符。
在选择重新启动之前，安装最终将呈现以下布局：
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
...
|-sda1 8:1 0 1G 0 part /target/boot/efi
`-sda2 8:2 0 23.9G 0 part
`-md0 9:0 0 23.9G 0 raid1
`-md0p1 259:1 0 23.9G 0 part
`-dm_crypt-0 253:0 0 23.9G 0 crypt
`-vg0-lv--0 253:1 0 23.9G 0 lvm /target
sdb 8:16 0 50G 0 disk
`-md1 9:1 0 50G 0 raid1
`-dm_crypt-1 253:2 0 50G 0 crypt
sdc 8:32 0 50G 0 disk
`-md1 9:1 0 50G 0 raid1
`-dm_crypt-1 253:2 0 50G 0 crypt
sdd 8:48 0 25G 0 disk
|-sdd1 8:49 0 1G 0 part
`-sdd2 8:50 0 23.9G 0 part
`-md0 9:0 0 23.9G 0 raid1
`-md0p1 259:1 0 23.9G 0 part
`-dm_crypt-0 253:0 0 23.9G 0 crypt
`-vg0-lv--0 253:1 0 23.9G 0 lvm /target
...
然后我进入 chroot 到 /target 并安装了 mdadm、cryptsetup 以及 lvm2，然后运行update-initramfs -u -k all，
检查 md0 的状态，我发现它正在运行并且完好无损。

据我所知，一切似乎都配置正确，但第二次重启后仍然进入 grub 提示符……
什么配置不正确，或者我遇到了错误？
