我的旧笔记本在启动时出现问题。如果我选择加载 Ubuntu，它会进入控制台，所以我尝试从 grub 启动，因为它说(initramfs)我无法运行，所以我尝试从 grub 加载 ubuntusudo fscksudo not found正如我在这里读到的。但启动后(initramfs)控制台也出现了一些错误：
Begin: Running /scripts/local-bootom ... done.
done.
Begin: Runing /scipts/init-bottom ..mount: mounting /dev on /root/dev failed: No such file or directory
done.
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such fiule or directory
Target filesystem doesen't have requested /sbin/init.
No init found. Try passing init= bootarg.
我该如何启动我的系统？我该如何解决这个问题？
