I do not think this will work, because when the op deleted the /boot
partition, the installed kernels and everything except the first
stage Grub loader were deleted. The kernel(s) and the rest of Grub
can probably be copied from the second install, but the
init-<version>.img will have to be rebuilt to use the proper volume
group. Then the grub.conf file will have to be edited to change
VolGroup01 to VolGroup01. Then doing a grub-install would work. But
it would also stop the second installation from booting. You would
ether have to change where the first stage gets installed, and the
add a chainload entry in the Grubconf on the second drive. Or modify
the Grub install on the second FC5 installation, and chainload from
the frist install.
