我在双启动配置中安装了 Ubuntu 和 Windows。Windows 出现一些问题，因此我决定重新安装它。我删除了 Windows 分区并在那里重新安装了 Windows。我还删除了另外两个我之前没有创建且无法识别的小分区。
我有一个 SSD，上面有两个分区。一个用于 Windows，另一个用于 Ubuntu。
现在我无法启动 Ubuntu。我尝试了几种方法，包括启动修复，但它告诉我：Error: NVram is locked (Ubuntu not found in efibootmgr). Please report this message to [email protected]

我现在该怎么办？如果我需要重新安装 Ubuntu，有没有办法使用 Ubuntu 分区从中恢复应用程序和配置，或者我需要从头开始？我上面有很多应用程序和配置。
