Dual boot recovery - windows 7 boot recovery

Hello, my HD is divided in 3 parts which was: i had dual boot with windows xp 64, windows 7 64, and another windows xp 64(this is a old installion which i had problems with system files) but the help i want ask here is because i of that fault windows xp i installed a new copy in this new copy i messed the boot with easy bcd i deleted windows 7 informations now im not able to boot into windows 7 i was able to fix the windows xp boot using the cd repair console and the command bootfix, but now i need fix the windows 7, i have the cd but the cd installs the home edition and the windows 7 i have is the ultimate so im not sure if it works for recoverng the boot... also i'm afraid of trying it and it deleting the windowsxp boot information.
p.s when i boot i the computer shows me 2 options to boot into the old xp installation and the new so it shows:
windows xp professional
windows 7 (i added from easy bcd, but it has no boot information at all, nothing)
so i choose windows xp and then appear other options:
windows xp on D:/
windows xp on E:/
this is pretty annoying... someone help me please? Forgive my english language i tried my best to be clear.

If you boot from a Win7 DVD, you should be able to run Startup Repair without reinstalling the OS. You might need to run it three times to get startup working again.

Can you explain step-by-step what to do please
and what about my windows xp, will it appear in boot or will disappear?
