我有一个双启动系统（实际上是三启动系统）。一直在使用安装在 MBR SSD 上的 Ubuntu 16.04 和安装在 SSD 驱动器上的 Windows。我在 nvme 驱动器（UEFI）上安装了 Ubuntu 18.04，在将 Windows 转换为 UEFI 后，它似乎可以正常工作。
系统是新的 i7-8700K 系统 16 GB 内存，配备 nvidia 1060 gpu
我无法启动到 18.04，但知道如何通过尝试启动到修复模式来解决这个问题，然后我就成功了
e2fsck -b 32768 /dev/nvme0n1p2
现在它可以启动了，但仍然抱怨找不到 uefi db 列表且缺少密钥。
以下是来自 dmesg 的一些可能相关的行：

请提供建议。我应该重新安装还是有解决办法？尝试过启动修复，但情况更糟。
谢谢，罗伯特
