Dual Boot Windows XP(Primary) and Windows 7 (Logical Partition)

I have disk with 3 partitions, XP (C) is primary, Win 7 (D) is Logical and (E) is Logical and a data drive. I used a dual boot program to choose which OS to use at start up. I did this to preserve XP apps in case they wouldn't work on Win 7. Now I want to delete XP and have Win 7 as the primary partition (C) and data as Drive D. I cannot change the current Win 7 D drive to a primary partition or change the current C to a logical partition.
I tried using EasUS Partition and it won't let me do what I want. I hope someone can understand what I am trying to do and help me out. Thank you

I would do a complete reinstall. Get your data off ( backed up ) wipe everything, make 2 partitions and install 7. All your partitions should be primary.

That's what I was afraid of

Thanks for the info. Before I press the button on EasyBCD, could you look at the boot info I have to make sure what I want is correct (Make D my boot drive then delete C)

EasyBCD info screen
There are a total of 2 entries listed in the bootloader.

Default: Windows 7
Timeout: 30 seconds
Boot Drive: C:\

Entry #1
Name: Earlier Version of Windows
BCD ID: {ntldr}
Drive: C:\
Bootloader Path: \ntldr

Won't let me do it - D is a logical drive
