我的ROG zephyrus 16上安装了ubuntu22.04和window11双系统，之前两个系统都运行得很好，今天从window切换到ubuntu的时候发现报错。
ALERT! UUID=xxxxx does not exist. Dropping to a shell!
我仍然可以启动 window11，但无法再启动 ubuntu。
然后我使用 USB 驱动器启动 ubuntu 并尝试修复系统。
这是有关我的系统的基本信息。

我采用了这个方法。
修复
ERROR: resume: hibernation device 'UUID: xxx' not found当 中的 UUID/etc/fstab与实际 UUID 不匹配时，可能会发生此错误。使用lsblk检查设备的 UUID，然后更正 中的信息/ect/fstab。然后打开/etc/default/grub并更改此行：
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor resume=UUID=<correct_UUID> udev.log_priority=3"
修改完之后别忘了更新grub：
sudo update-grub
我的 fstab 不包含 UUID，因此我将其添加到文件中。然后我想更改 /etc/default/grub 并更新它。但是当我运行 sudo update-grub 时。它给了我一个错误
grub-probe: error: failed to get canonical path of /cow
我尝试了另一种方法，尝试使用 boot-repair 来修复我的 ubuntu 启动。但它不能正常工作。有人知道它出了什么问题并能帮助我吗？
