今天，我的装有 Ubuntu 22.04 LTS 的电脑停止工作并直接进入 BIOS。启动驱动器不再显示在 BIOS 中，而且 GPT 分区表信息似乎消失了。我将 SSD 放入机箱并从 Ventoy USB 加载实时 Ubuntu CD（https://www.ventoy.net）然后我运行 Boot Repair 工具，工具报告可从以下链接获取：https://pastebin.ubuntu.com/p/dhGrzkgqMk/。
我没有使用 Boot Repair Tool 进行任何修复，当我尝试从实时 CD 访问 SSD 上的 Ubuntu 分区时出现错误：can't read superblock on /dev/sdxx。
SSD 尺寸为三星 SSD 970 EVO Plus 1Tb。

在升级到 22.04 LTS 之前，我大约 2 个月前有完整的 Veeam 备份。有什么方法可以从这两个损坏的分区恢复我当前的数据吗？
