clone multiboot two disc win7 xp install to win7 ssd plus disk XPx64

I have a multiboot win7 /xpx64 TWO DISK system, showing win7 as the C; drive and XPx64 as D: when examining via My Computer.
Cloned the C: drive (win7) using Samsung tool to same size Samsung evo SSD. When put in computer the dual boot option gone. The SSD clone of win7 runs ok, but with that in alone (no XP disk) My Computer now shows two drive, C: local disk 488GB free of 931GB, and D: Data 100Mb containing a folder Boot containing folders such as cs-CZ containing a single file such as bootmgr.exe.mui
Minitool Partition shows
D: Data primary active&boot
C: system
.....
(Trying to fix the multiboot on the original installation has killed the old XPx64 disk drive (now unrecognisable during boot) and left me with a system having only win7, and no boot loader showing during startup.)
.....
What I want is a duplicate of the original setup but with the SSD running the win7 section. Am prepared to reload the XPx64 as reinstall, although I have a copy of the XP drive if that could be somehow reattached. or if the damaged XP disk could be repaired.
My guess is that the problem comes from the cloning not being what is should, ie bit for bit image of the original disc including MBR etc. (Correcting this would not help because I have damaged the original setup.)
For a start, is it possible to make the SSD run win7 but appear as a single drive,and then add a disk and load XP and have it show as D: (This keeps all the higher disks with their original labels, ie DVD E: datas F: G: and H:)

PW confirms that C is the booted OS as signified by the System label - while in Disk Mgmt this label would be Boot. The boot files actually booting Win7 are on D as signified by System Active.

To confirm this please post back screenshot of Disk Management - Post a Screen Capture Image and we will tell you how to correct it once we know for sure. If it confirms it by showing the labels reversed (which would be correct due to PW's unusual labeling scheme) then as long as C is a Primary partition you'd simply Mark C Partition Active and run Startup Repair - Run 3 Separate Times to move boot files to C.

The best way to configure a Dual Boot on separate HD's is to set have each HD boot itself, then set preferred to boot first in BIOS Boot Priority, boot the other (XP) using the one-time BIOS Boot interrupt key at boot. If this is not to your liking, install EasyBCD to Win7 to add XP.

But we need to sort out your Win7 boot first so let's see the screenshot. Confirm also whether XP partition is marked System Active in DIsk Mgmt, or Boot Active in PW.

Thanks for above. Have a hotswap caddy machine, but dare not put in XP disk until above sorted. Please find screenshot attached. Cheers.

That isn't of course Data partition but a Win7 System Reserved partition intended to boot the OS and apparently doing it correctly. The only change required is to remove the D drive letter in Disk Mgmt after relabeling it in its D Properties box

Go ahead and plug in XP alone to see if it will boot and post back its DM screenshot pasting Print Screen into Paint to Save and Attach. If wont start then plug in 7 drive set first to boot and post 7 DM screenshot of both.

Sorry to be obtuse, but could you please expand on this. No idea what you are referring to, unfortunately.
Re plugging in the XP disc, I would have to take the SSD back out the rack. Unfortunately, the SSD on its hotswop carriage is literally a jam fit into the bottom slot of the Supermicro case, so I am reluctant to pull it again. Would rather fix it, then put in the XP disck and see what win7 or minitools PW says.

I want my computer back the way is was, but with an SSD in C instead of the original drive. I have corrupted the original setup stack, so Greg's solution works for me, otherwise I have to crowbar things in and out to even be able to copy/image things.

Rightclick on D in Disk Mgmt to Change Drive Letter, remove drive letter.

Fix what else? You want XP on separate HD correct? Plug it in to see if it boots. If not take a picture of PW CD drive map showing all listings. Otherwise Repair Install or reinstall XP to it HD with SSD unplugged.
