我有一个 ISO 映像，它从我的 SSD 上的一个分区启动，该分区由 UNetbootin 创建，它会自动启动安装。这是我试图安装的同一个 SSD，我知道它很奇怪。它确实按预期运行了我的ubiquity/early_command& partman/early_command，所以我知道它正确地拾取了预置文件。
如果我Ctrl-Alt-f2进入控制台窗口，我得到的只是一个空白文本屏幕，光标位于左上角。
在安装窗口中我收到错误“Ubuntu partman：未找到匹配的物理卷”。 验证安装配置
我知道通常没有人会将同一个驱动器用于安装介质和目标，但这不是正常情况。我们在现场有几千台这样的设备，已经安装并运行了 Windows 7。我们正在尝试创建一个可以用 Linux 替换现有 Windows 安装的过程，并且以不需要用户交互或干预的方式执行此操作，我们真的不想将它们送回工厂重新制作映像。我已经能够为 ISO 创建新分区，将 ISO 文件复制到新分区，然后重新启动进入 Linux 安装程序，并使用partman/early_command简单的 bash 脚本删除现有的 NTFS 分区。
如果我无法让 partman 创建我需要的分区，是否可以使用fdisk或在我的 bash 脚本中自己创建它们parted？

更新：我现在可以在安装程序运行时获取系统日志。
以下是我认为与日志相关的部分。消息“未找到 NTFS 分区！”来自我的 partman/early_command 脚本，该脚本查找并删除任何现有 NTFS 分区，因此我知道它至少正在运行。
我还更新了上面的预置文件以匹配我目前正在使用的内容。
