hmmm, how are you going to get to your menu file if you can't boot it?
1) first thoughts are looking at your disk free info is that the only linux (reiserfs) is on sdb2 and no mention of any linux on hda partiitions.
2) hda1 missing in df may because it is no longer in your linux /etc/fstab?
3) but how to be sure? if you can get to grub the MENU not the menu file, you can try my trouble shooter to test each hd number and see what file system is reported

eg you are at grub menu now press C for commands
a) type root (hd and press tab to see whats available
b) type root (hd0, (comma) and then press tab to see what partitions are available
c) change hd0 to 1 then 2
4) Do you have a boot disk? if so try that it may be quicker to get into FC?
5) Assuming FC truly exists you can amend your menu list file or /etc/grub.conf to resemble your new partitiions.
Hopefully
