Thanks for the tip!
My experience with the FBSD boot manager is virtually zero, so I can't address it's workings, but I use GRUB as a booter just because it gets me out of so many jams like yours -- if something isn't where you thought it was you can point GRUB at your disks and let it do the looking for you.
The secret is to make a boot floppy with GRUB installed on it. Once you have that there's no machine that's unbootable, and you can reinstall GRUB in seconds if it gets overwritten by Bill & Co.
For example, IIRC, I just went thru this myself (although it's all so routine now I can't even remember what I do to bail out anymore) when I installed XP on a brand new disk and then installed FBSD afterwards. I got the MBR screwed up just like you, then ran the XP install disk in "Repair" mode which got XP to boot again but overwrote the FBSD booter. So all I did was boot my trusty GRUB floppy and reinstalled GRUB on the MBR in about 60 seconds and -- done.
The next evil news is that I've never really gotten FBSD's incarnation of GRUB to work right for me, so I just install in on the floppy from a linux machine and use that for the FBSD machine.
If you have access to GRUB and need instructions I'd be happy to help. Just let me know.
I'll give GRUB a try :)
Andrew.
