我正在尝试安装 Ubuntu 服务器，但它总是在更新 grub 的最后阶段卡住。我取消了这个过程并重新启动了我的系统，它把我带到了 grub 命令提示符grub>。
我尝试从提示手动启动：
root=(hd1,gpt5) # Ubuntu root partition
linux /boot/vmlinuz-something- root=/dev/sda5
initrd /boot/initramfs-something-
boot
<enter>
滚动一些启动消息后，它让我陷入
Busybox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3) built-in. shell (ash)
随着initramfs>提示。从这里我做了一个exit
它向我展示了内核恐慌！有以下两个提示。
mount: mounting/says on /root/says failed : No such file or directory
mount: mounting /process on /root/process failed: No such file or directory
