I'm afraid there was a misunderstanding in your last thread: you and garycase seem to have misunderstood one another.
EasyBCD only works whem installed on Vista and Win7, it does not work from within XP. So you should have installed it on Win7 - which wasn't possible since your Win7 no longer booted.
The correct way to get your old Win7 bootloader back would have been to boot off the Win7 installation DVD and have it repair/reinstall the boot files. For this, please refer to "Method 1" in this resource:
http://www.windowsreference.com/windows-7/how-to-reinstall-windows-7-boot-loader/If repairing with the Win7 installation DVD should not be able to resolve the issue for some reason, reinstalling Win7 would have bee the solution: it would detect your existing XP and integrate it into the bootloader.
I guess both options should still be available, although I am not quite sure what the failed EasyBCD installation could have broken.
