我是这样做的，先 dd 一个空文件，wangdu2002 写了： 熊哥要补充一下才好啊，怎样在没软驱的情况下搞出那个软盘引导映像，直接引导之。
盘符在 HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices 里控制，用的也是 uuid 一类的东西。移动自然是不妥的，但如果用 ghost，会把 uuid 一并克隆过去，盘符不会改变。我把第一主分区的映像恢复到某个逻辑分区，启动后这个逻辑分区就叫 c ，一切正常。而 e 盘的 windows，删除 c 盘后启动，仍然叫做 e 盘。注册表里，c 盘, e 盘 就是对于某个 uuid 的分区。hubert_star 写了：
但是，安装好以后，移动到别的盘，很多软件的内置注册表路径会有问题，要全部改变盘符，尤其是sp补丁这类的东西
ghost版的xp目前基本上存在两种不同的封装方式，一种是己写好引导代码的，引导方式也是通过 ntldt + boot.ini 引导的，按理这种ghost镜像应该是可按理说，那些 ghost 版的 xp 应该能这样被安装到逻辑分区里的，我测试了深度的版本，可以启动，但是没等完成安装驱动就死机了。还不清楚原因。

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
The number of cylinders for this disk is set to 2610.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

看来此法古已有之。在受到 climbing 先生启发之前我一直没有往这方向想过。yanqian 写了：不错，讲的挺好！
之前红旗论坛（后来转到Linux-ren论坛了）上有个类似的帖子，真是巧啊：

不过因为红旗论坛的资料转到Linux-ren后，格式都乱了，图片也没有了，只能将就看了……
