Dual boot Window 7 to Single boot

As some software I use works better with more than 4 gb of memory than 32 bit Windows 7 allows, I made a second partition on my hard drive and installed Windows 7 64 bit on it so I could carry on working on the original partition until I installed all the software, I have completed this and it appears to be working correctly. I can select which version boots from the Windows 7 boot menu.
I now wish to move the second 64 bit partition to be the beginning of the drive and remove the 32 bit partition.
I have TI 2014 Premium and have images of the full disk (both partitions) and just the 64 bit partition after installing my software. I have tried to restore the 64 bit partition a number of times with different images including resizing the partitions.
None seem to work as expected sometimes they refuse to boot (I have restored the MBR), and the repair boot from the windows DVD didn’t work or sometimes the Windows 7 boot menu loads with just the one item.
As an aside, I have noticed that in the Rescue Disk restore screen where the active partition can be set the resizing partition options seem to have a mind of their own and won’t always stay at the figures entered!
If I restore the whole disk backup from the TI I get back to where I started with a dual boot system, which where I am now.
I attach a jpg of the disk manager window if that helps in any way
PS All my data and images are on the second hard drive
Any help as to what I am doing wrong will be appreciated
