Nope, I don't believe there is a backup of the mbr anywhere - that it
the partition table that has two copies.
Interestingly, the recent mbr boot sector virus doing the rounds last
year made a backup copy of the mbr at sector 62, so if you'd happened to
have been infected then you could have recovered your original mbr from
that, but I guess you're out of luck.
You haven't lost any data thought, just your ability to boot. A trip to
corporate IT may be in order.
