The "problem" is that you cannot clone or move any version of Windows installed on an OEM (Lenovo, Dell, et alia) system...to another system. That copy of Windows is licensed only for use on the system that it came installed on. Dell licenses are not valid on HP systems and the hardware settings are totally different. The system partition on one does not transfer to the other.
FWIW: It appears that you are correct in assuming that the Dell system originally employed a 32-bit instruction set and would not have been able to run a 64-bit version of Windows...but the reverse is not true. Any 64-bit computer can run both 32-bit and 64-bit versions of Windows.

Possibly pertient...if my memory has the dates correct.
Dell systems used to be sold with installation disks which were copies of Genuine Windows XP with a few minor additions/modificationsl. These disks were pre-SP3, which was issued (May 2008) and before the OEMs began rigorous implementation of recovery partitions and recovery disks. This was the pre-PA era and, as the records will document, everyone with a system had a copy of XP available for install, if desired.
These disks were, up until 2005, subsequently sold by some retailers as "Windows XP installation disks" and could be installed on any system, same as a retail version of a Genuine XP disk issued by Microsoft.
Once the OEMs (particularly Dell) stopped issuing full versions of Windows XP with their systems...the result was "recovery disks" and "recovery partitions", which are the norm for OEM systems since 2005.
But...Win 7 was released long after the above mess was cleaned up and recovery partitions, recovery disks, and product activation were well in place.
When you dual-booted...the XP install files were overwritten/made useless by installing Win 7 and it's the Win 7 install which controls the dual-boot of XP and Win 7. So cloning the drive at this point...results in a Win 7 boot files clone.
Copying boot files from an XP partition on a dual-boot...will not result in a bootable Windows XP...or a bootable Win 7, in your case. You could delete the existing install on the new system and install XP with your old disks (probably) but that would screw up the existing Win 7 install on the new system.
Or, if you have recovery disks and no recovery partition...you could manually reinstall XP, then install Win 7 anew.
I think that you may be confused by the fact that Win 7 was already installed on the new system...and I suspect that is the Win 7 install which you now boot into and reflects no problems.
