正如标题所述，我有 5 个磁盘映像，，，，，dev-sdc1.img。我没有保存分区表，也不知道哪些是主分区等。它最初来自具有 GUID 分区表的 Windows PC dev-sdc2.img。dev-sdc3.imgdev-sdc4.imgdev-sdc5.img
我如何将它们拼接成一个具有有效分区表的分区映像，然后将其复制回与原始分区大小相同的驱动器上？ 我可以接受主/逻辑部分与原始部分不一样。
我将使用 Lubuntu 或 Ubuntu Mate 以及任何适用于 Linux 的工具。
编辑：人们问为什么，这原本是一台 Windows 笔记本电脑，我决定在上面安装另一个操作系统，并单独备份分区。我不确定某些分区的用途（不记得这是出厂时安装的 Win 10 还是手动安装的），所以我将它们全部备份以便以后查看数据。后来我改变了主意，不再使用其他操作系统，因为我最终需要一台 Windows 机器，所以我试图重新安装 Windows。但是，我第一次尝试通过创建分区表并将gparted映像复制到磁盘上来手动将所有分区复制dd到磁盘上，但未能启动。
询问的命令的输出：

答案1
在目标磁盘上手动创建（使用fdisk或类似工具）一个新的分区表，其分区大小与分区映像相同，然后将dd分区映像放到适当的分区上。
