升级Ubuntu 20.04至22.04后系统无法启动的故障求助及数据恢复咨询

昨晚我的Ubuntu 20.04系统更新提示我可以升级到22.04，当时正好有空就选择了升级。升级过程看起来一切正常，安装也顺利完成，但重启的时候出问题了——屏幕上显示几行内容大概10秒后，就只剩一个闪烁的光标。现在每次强制重启都是这样：先显示几行文字，然后黑屏加闪烁光标，完全进不去系统。

我是Windows 11和Ubuntu双系统，开机时会出现选择菜单，里面有“Ubuntu高级选项”，下面有4个不同的选项，不知道能不能用这个解决问题？

我的系统是不是彻底坏了？必须重新安装吗？就算要重装，能不能先恢复系统里的数据？这些Ubuntu高级选项有没有用？

参考信息：Ubuntu高级选项内容 #

下面是我看到的Ubuntu高级选项列表：

• Ubuntu, with Linux 5.0.95-generic
• Ubuntu, with Linux 5.0.95-generic (with recovery mode)
• Ubuntu, with Linux 5.0.75-generic
• Ubuntu, with Linux 5.0.75-generic (With recovery mode)

系统启动时显示的错误日志 #

启动时短暂显示的几行错误内容如下：
