As far as I know there is no magic file of this kind -grub takes its 
information from its grub configuration file. Partitions are just 
partitions -system partitions will contain their own OS files, but they 
become "owned" by an OS just when the OS boots.

I guess yours is a work of patience -boot from a live cd, mount the 
different partitions, take note of what is there and guess which OS 
corresponds ; then check where is your grub installation, edit that 
grub.conf file, and if you didn't mess your partition table, you should 
be able to boot everything back correctly.
