How to remove an old OS from the boot menu

When I upgraded from Windows XP to Windows 7, I had a second drive around and set it to dual boot.

After a while, I decided that I wasn't ever going to go back to Windows XP, and so I deleted the windows directory on that drive. Unfortunately, now I can't remove Windows XP from the boot menu.

I tried going into MSCONFIG to the boot tab, but it only lists windows 7. I don't know if it's still going off of the Windows XP Boot ini.

edit: Before:
C:\Windows\system32>bcdedit /v

I'll have to wait until later to restart it and test it out though
