例如运行 sudo apt-get upgrade 后，会生成以下错误代码：

重新安装 intitramfs-tools 不起作用。有人知道问题是什么以及如何修复吗？
编辑：问题源于 lilo.conf 文件。这里定义了以下目录：boot = /dev/sda root = /dev/sda1
但是，我认为这不是启动设备，也不是根分区。我已将所有设备列在下面：

例如，如果我将启动项更改为 /dev/nvme1n1p3，则会显示以下错误：
Warning: SATA partition is in the high region (>15)
LILO needs kernel in one of the first 15 SATA partitions. If you need support for kernel in SATA partitions of the higher region than try grub2 for this purpose!
Fatal: Sorry, cannot handle device 0x10308
我不知道如何调整某些东西或如何使用 grub2，那么有谁知道如何解决这个问题吗？
