There's only one way to approach a problem like this without spending a lot of time and money, and even then.....
Use your XP CD to perform a CLEAN install on an EMPTY hard drive. During the process, the installer will "ask" for proof of (any previous MS OS). Simply stick/jam/shove your ME cd in "there", the installer will girate, wash, dry, and pronounce, "well, alrighty then"
