You left the old Windows 7 on the HD instead of installing over it. It is shown in the screenshot as D, with it's old 100mb boot partition immediately to its left and now abandoned.
This would be okay - we could just have you delete D and the small boot partition and resize C into its space - except that you installed to a Logical data partition which cannot host boot files, so it placed them on the old Windows 7 partition D.
Your choices are to start over by booting the installer to use Custom drive options to delete all partitions, create and format New one(s) as you wish as shown in Step 6-7 in Clean Install Windows 7.
Or you can boot free Partition Wizard
bootable CD, righclick on C to Modify>Set to Primary, click OK. Then rightclick C again to Modify>Set to Active, OK. Then click on the HD to highlight it and from Disk tab select Rebuild MBR, click OK, Apply all steps.
If Windows 7 doesn't start boot into Windows 7 installer to run Startup Repair - Run up to 3 Separate Times
until Windows 7 starts and holds the System boot files.
Now that you know Windows 7 will boot from C partition, you can boot again into PW CD, rightclick D and the 100mb partitions to delete, click OK after each, then rightclick C to Resize, drag left border all the way to the left to take up the space you deleted, OK, apply all steps.
