Did you specify to customize the partitions? If not it goes right past that part. TryThis is a bit confusing - when selecting "use entire disk" during Fedora install, it doesn't propose a boot patition, even on a 8 GB drive. Why?
You should always have a /boot partition. F14 is making this 500Mb, but TENDS to only use ~50Mb. This is for your own protection so that during a kernel update, you don't run out of disk space then end up with an unbootable system.
If you never run out of space in / and it never gets corrupted, you don't need a separate /boot partition...
df -h
and see what your partitions are, or Applications -> System Tools -> Disk Utility to look at the partitions graphically.
