You could add a stanza for FC7 to grub.conf

None if you are not using *BSD or MS products on the same machine

Decide which system is like to be the longest lasting. Boot into that.
If it is FC7, you can add a stanza to the FC3 grub.conf to boot it.
Amend the grub.conf to be able to boot both systems. My grub.conf for
the machine I am typing on is in my FC3 install. I am currently booted
into FC7. Take pointers from it and amend yours to suit. If you decide
to use your FC7 grub, you will need to install that. Read up on the
grub man/info page on that.
