How to clone a W7 on a standalone disk (2 partitions: boot loader and system) on a disk with existing partitions (Linux)?

[Uwe Dippel]

I have a problem that can't occur for the first time. ;-)
I have a W7 install in a secondary hard disk. During install, the installer on its own decided that it would create a small boot partition, and a large C:. Normal.
The problem comes in, when I want to clone W7 to another drive with another OS already on it: I can't do a disk clone, because it would overwrite the existing system, I can't do a partition clone, because then the boot loader would not be there.
In a nutshell: How can I transfer the W7-install from a singular disk to a disk with more operating systems on it; so that I can use grub to point to the W7 installation for booting?
If need be, I'd have the legal product key for W7, but no install DVD.

I believe you need another temp storage to put the image in order to transfer the system.
BTW, for MS windows, it's complicated to me so I actually have no idea how to let W7 to know the layout has changed so that it could boot from the right partition.
Anyone on this forum has idea?
Thanks.

So the best I could think of would be to transfer two partitions, and hoping for W7 to not whine when the main system lives in a different partition, though hopefully under the same UUID?

First BACKUP your data on external drive.

Two or more windows (V/7/8) need just one Windows Boot Manager but different partitions.
You can just clone/copy windows partitions to one drive and edit boot parameters of working installation 
If i remember corectly grub2 has a option of direct booting windows even without MSBootManager.

Two partitions with same uuid on the same system typically could not boot if they are pointed with uuid (now default for windows boot manager with uefi, grub).
Install dvd's are downloadable legally from internet but they well overwrite grub.

Yes, I hope so, too.
