I know you have probably tried this & it might sound just tooo simple, bordering on lame, but did you do a search (find files or folders) from xp or 2k ?
I don't know if this will help, but here is my boot.ini You can substitute appropriate o.s. descriptions & partitions for your config. That is if you ever find your correct boot.ini file.
[boot loader]
timeout=3
default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="WIN 2K" /fastdetect
C:\ = "WIN ME"
