I've noticed a couple of threads complaining about just getting a grub prompt on trying to boot FC4. I've found one reason that this happens, which may be relevant to other users. I have a dual boot system so hda1 is reserved for windows. I tried using the auto-partition facility to set up the rest of the hard drive for FC4. This booted ok and would have worked except that I need to replace the libvgahw.a file to get a usable display so I have to edit the root partition before I can boot. Knoppix couldn't read the default LVM setup, so I tried manual partitions. Following the example of the automatic setup, I made a separate boot partition, as hda2 and then root as hda3. This arrangement wouldn't boot - I just got the grub prompt. The boot partition seemed to have the right files, but there was another boot folder in hda3 which was empty and I think this gets mounted on top of hda2 and hides it. At this stage I tried again without the separate boot partition and it started to boot normally again. Maybe it would also work if you removed the empty boot folder from the root partition, or put root on hda2 and /boot on hda3. I didn't try - I had had enough of it at this point! Incidentally, I was also thrown by the installer deciding to give me a hidden menu at boot up, making me think I had lost windows. I've cracked it now, but why doesn't the installer give an option and why should it suddenly work differently?
