Partition table corrupted

I upgraded my server motherboard, reinstalled Windows 2000
server to get the proper drivers installed, etc..
Everything worked fine except that my drive letters where
not correct.... and then I was (sooooo) stupid:
I reassigned them using the disk manager without
installing any SP first and of course on a large drive!
So my partition table is corrupted and my disk is
unbootable.
How can I fix that (hopefully nothing should have been
deleted beside the partition table) and I have a spare XP
SP1 system if needed to connect the drive.
As you might guess I would like to recover the data
present on the drive as I don't have backup and as it's a
small network the W2K was the only controller in the
domain... so the forest root would need to be recovered
too!

Thanks.

Disk is unbootable.... are we getting any blue screens?
What exactly happens when we try to boot from the drive.
