you didn't post the whole grub.conf so it's not possible to compare it
to the entry for FC5

Obviously we now know you have 2 hard disks so it probably would be
helpful to show output of

fdisk -l /dev/sda
fdisk -l /dev/sdb

yes, if you remove 'rhgb quiet' entries from grub, you would see more
debugging information on screen but you can do that temporarily at boot
time by 'editing' the grub entries at boot time or I think pressing the
'ESC' key while starting up.
