Description of problem:
I have a Compaq R3000z (Athlon64) which has had this problem occur
although I believe it occurs on other platforms and may have been
reported against grub rather than anaconda (see
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=139140 ).


I have lots of disk space on the R3000z and after strinking the ntfs
partition for WinXP down to a reasonable level (8GB), I have installed
FC3 on the system (in fact, both i386 and x86_64 versions).  The disk
layout is:

/dev/hda1 -- WinXP (C-disk)
/dev/hda2 -- Linux swap
/dev/hda3 -- minimal FC3 install as "boot director" and
             grub installed into MBR
/dev/hda4 -- extended partion for rest of disk.
/dev/hda5 -- 15GB partition for FC3 i386
/dev/hda6 -- 15GB partition for FC3 x86_64
/dev/hda7 -- rest of disk for common /home

After installing the "boot directory" and getting it to boot up, I
added "chainloader +1" entried for hda5 and hda6 to /boot/grub/grub.conf

I then did everything installs of FC3 i386 and x86_64 into their
appropriate partitions.

I do not recall if I had any problems with the full i386 FC3 system
and I worked with it on the R3000z since I had to play around to get X
and other stuff configured correctly so things work.

Today, I started in on the x86_64 system ... oops, grub failed when it
tried to boot up.  OK, boot the install CDROM in rescue mode and run
grub from the chrooted system:

  root (hd0,5)
  setup (hd0,5)
  quit

Reboot but now it hags tring to do stage2.  OK, reboot the rescue
cdrom and run:

  grub-install  '(hd0,5)'

Then reboot and success!

While I found out how to get the system up and running, this should
not have occurred.
