sda1 保存/boot/efi/EFI/，sda3 保存 Ubuntu 系统，sda4 保存/var，sda6 保存/home。从 initramfs> 提示符，我想知道启动系统的命令。尝试启动最初转到 grub> 提示符，然后通过退出到 initramfs，报告找不到缺少 mdadm 的本地块脚本（系统上没有 raid）。udev 是否未能完全填充/dev？
其他硬盘包含可启动的 Ubuntu 22.04，但启动 sda 系统的确切命令序列尚不清楚。
启动修复后 pastebin 报告位于https://pastebin.ubuntu.com/p/HXs2PWqj9t/任何想法都将不胜感激。或者，如何重新安装 Ubuntu 而不丢失设置/etc？

You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 22.04.4 LTS entry (sde6/efi/ubuntu/grubx64.efi file) !
Following some further work:
After deleting stuff like cache files, /sda3 is a lot less. After some attempts to get sda1 to boot, it now gets to the screen showing the installed drives with operating systems. Clicking on ubuntu boots up but does not complete saying "Running /scripts/local-block... mdadm. No devices listed in conf file were found. Gave up waiting for root file system. ALERT! /dev/sda3 does not exist. Dropping to a shell. ". Then a note on busybox and the (initramfs) prompt. BootRepair wants to repair a different drive. There's no raid on this system. Any thoughts/ideas?```
