I had the exact same problem as post #15. I have two HDDs in the system. Windows/Ubuntu (6.06 and 7.10) are in the SATA HDD. I installed Fedore 8 on the IDE HDD which has also Windows DATA partitions and Linux DATA partitions along with FreeBSD 7-Beta.
I ended up going back to Fedora 7 which is working fine. It is really a pity. The installation process from the live CD was quite smooth. It just did not boot after the "flawless" installation.
