以下分区、mktable、mkfs、mkswap 会清空选中磁盘/分区的数据。这是当时的全盘安装记录，不适用于保留现有系统的双启动操作。只在已确认的目标空盘，或已决定擦除且备份并验证恢复的目标盘上继续；不要照抄历史设备名 /dev/nvme0n1。先备份重要数据，断开不需要的外置盘，并用设备型号、序列号、容量和挂载点核对目标。不能确认时停止，不执行分区或格式化。

下面保留当时的交互笔记，但使用由你手动填写并确认的 $DISK、$ROOT_PART、$SWAP_PART、$EFI_PART。先完成独立的只读确认步骤，分区完成后再核对各分区对应关系；整段笔记包含交互命令和配置摘录，不是可整块执行的 shell 脚本。
